Box Moth & Caterpillar Tracker

Get an early warning

With your help we can give each other an early warning of when Box Moth & it’s caterpillars are active.  Using the map below you will be able to see reports from people across the country.  They will be updating information on the state of their traps and caterpillar activity in their box hedges & topiary.

A large infestation defoliated about 2 thirds of my box plants. I sprayed several times over summer and autumn with Xen-Tari which stopped the infestation from spreading to the front garden. However I just spotted they are still active in January on the plants where the initial infestation was. The caterpillars are much smaller, 3-4mm long, but still atacking new small leaves.

Note from EBTS UK: It is unusal for the caterpillars to be active at this time of year as the combined temperature & amount of daylight should mean the small caterpillars have entered diapause (wrapped up in webbing between two leaves with development paused until the temperature and sunlight increase).

Any chance you could email some pictures to

Moth Trap

2017-06-29Eastbrook Road, Waltham Abbey EN9 3AL, UK

Two 16yr old box balls lost to caterpillar over a fortnight.

Note from EBTS UK: It looks like the balls would recover as long as they weren't allowed to be eaten again when the new growth returns.  If you haven't taken them out, make sure you feed the plants in the spring and keep an eye out for the moths using a pheromone trap and spray a week after you catch the first moth in the trap for each of the life cycles during a season.

Moth (image attached) spotted on door, near box hedge.

2018-09-243822 TC Amersfoort, Netherlands

In two weeks time - during our holiday - the Box Moth Caterpillars completely destroyed our 20 year old hedge - as well as any box plant in the wide vicinity. Nothing remains but stems completely stripped of foliage. Box plants are dug out en masse and go to compost heaps or green waste baskets. We replaced our hedge by Ilex plants as there basically seems nothing else to do. Box has all but disappeared from my city in just one year.

Note from EBTS UK:  Really sorry to hear that you have dug up your plants as there is a good chance they would have survived and in the spring they would have been covered with new leaves.  The key thing is to spot the symptoms as early as possible and spray with a Bacillus thuringiensis based insecticide (safe for everything but caterpillars).

Good luck with your Illex, you will need to check the soil PH value to make sure it is suitable and they also like a lot of sun compared to buxus.

Signs of caterpillars eating leaves, removed worse affected and sprayed

2018-09-26Revell Road, Kingston upon Thames KT1 3SL, UK

First noticed the caterpillars back in June this year.  Have physically removed the caterpillars by hand and used pheromone traps but have still lost 6 box plants.

Note from EBTS UK:  Although it might look like the plants are lost, unless the caterpillars have eaten the bark from the stems, the plant will likely recover.  Feed and water them and see what happens, it's cheaper than replacing with new box or a less good alternative.  Picking off by hand will only really work for small amounts of box and you will need to check the plant once a week for caterpillars.  We would recommend using a biological insecticide to manage things more effectively - there are a number of options some safer than others as far as other garden beneficial insects are concerned.

About 30 caterpillars found on beech hedging.

Note from EBTS UK: Would you be able to send a photograph of the caterpillars so that they can be identified.  Box tree caterpillars wouldn`t normally live on beech so it would be very helpful to see the caterpillars you have found.

2018-09-22Maidenhead SL6, UKAs a jobbing gardener, I have observed a number of the distinctive white moths in the Maidenhead area over the last week or so. I had not been aware of them before this year. Caterpillar damage, often severe, seen to many box bushes over the past 12 months.
2018-09-18Staplehurst Road, Reigate RH2 7PU, UK

Two moths found in my home, a four foot high box type hedge divides my front garden and next door neighbours.

Note from EBTS UK: Given the moths presence in your kitchen, it will be important to keep an eye on your hedge for caterpillars and take action with a suitable spray as soon as you see them.  

2018-09-09Ember Lane, Esher KT10 8ER, UK

Trap - within 1 week over 100 moth caught, I have over 120 by hedges individuals approx 20 metered.  Only spotted 1 caterpillar, however most plants have been damaged internally.  I have also sprayed with XenTari.  A close property with 400 meters has a well established box hedge approx 1 meter in height absolutely obliterated, owner had not yet treated - I assume I am catching a lot of moth as so close.

Note from EBTS UK: Certainly sounds like that is what is happening.  As long as you continue to spray regularly (roughly 10-14 day intervals) whilst the moths are flying this should mean your hedges don't get infested even if the eggs are laid by the moths from next door.

Moth traps installed, garden & allotment where there are 70cm high box to 7 foot high cubes of box. Installed range initially between 150cm - 7foot high. I have now lowered some so the range is 150cm - 50cm. Nematodes first used. Now I am using Zen Tari from Topbuxus Hedge at home has also been covered on the top ( not sides into the garden , with shade netting due to sun damage. However whilst this has been protective to a degree, moths that do get in get stuck under net. I have caught some by hand when possible.

Small 1cm caterpillars found on some parts of low box hedging - sprayed with XenTari.  Should have sprayed before going away for 4 days but thought it could wait till I returned - I should have heeded my Mothers regular quoting of 'never do tomorrow what you can do today'!

Regular spraying after moth sighting works well and is how the professional gardens manage to keep their hedges and topiaries looking so healthy and uneaten.

Update - 2 caterpillars found, over 50 found in pupa stage, mostly deeper inside Buxus, no moths in trap yet, deciding whether to spray with XenTari or not as I don't think it will affect the pupa stage, just the caterpillars - daily monitoring for caterpillars continuing.

Note from EBTS UK: You are right the XenTari will only affect the caterpillars, so if they aren't feeding on the leaves you don't need to spray

2018-07-06Church Lane, London N8 7BU, UK

Serious caterpillar infestation of two low box hedges. Moths spotted as well.

Note from EBTS UK: This does look quite bad, but it is possible that the plants will grow back if feed and watered.  To find out, try cutting a branch about 10cm from its tip and see if it is green, moist & supple.  If it is then the plants will probably survive, if however it is dried out, try cutting closer to the main stem and test again.  If it is dry right back to the main stem then it is unlikely to recover.

2018-09-07Grove Terrace, London NW5 1PL, UK

Caterpillars found in front garden box a month ago. Sprayed every two weeks with xen tari and fed with box feed. Hedge looks dreadful. No sign of caterpillars but moths flying around. Put moth trap out one week ago and about 10 moths in it. Not sure how to empty it yet. Will continue spraying and feeding hedge.

Note from EBTS UK: Take a look at the video linked below to show one way of emptying your BuxaTrap - hope it helps.

2018-09-04University Gardens, Bexley DA5 1QN, UK

1 spiral box tree affected over the middle of the tree. Leaves brown and lace-like. Adult moth seen. No caterpillars seen.

Note from EBTS UK: If the leaves have gone lace-like there is a good chance that the caterpillars are hiding deeper in the tree so it would be a good idea to kill them off by spraying before they cause any more cosmetic damage.

2018-09-04Burnham, Slough SL1 7DP, UK

No sign of caterpillars yet I have 5 lengths of box hedging and several single bushes.  I sprayed them all (I think) with XenTari Raupenfrei in the spring and then about five weeks later with Provado Bug Killer as a preventive.  I am surprised that it seems to have been so effective.

Note from EBTS UK: Good news that your hedges haven't been affected yet, continue to keep an eye out for caterpillars as there is still one more wave to come.

Seven box tree caterpillars found in box hedge. Caterpillars squashed and box sprayed with Resolva natural bug spray.

Note from EBTS UK:  Sorry to hear they pests have been found in your plants, but glad that you have spotted them.  In some very unscientific tests we carried out with a natural bug killer (not with Resolva) we didn't find it worked as it isn't powerful enough to kill caterpillars (which aren't unfortunately listed on the Resolva Natural Bug killer product).

Do let us know if it works though as it would be great to have another safer product that could be used.

Tried out a modified USB powered mosquito trap - it has led's to attract the moths combined with a small fan which sucks the moths into the trap.  I had noticed moths were going to the lures and flying off without entering the funnel.  There weren't many moths out in the garden when I set it up, however the catch successful catch rate was much higher.

32 x common + 9 melanic moths caught + a couple of what looked like clothes moths.

Note from EBTS UK: Don't forget the even though you are catching a large number of male moths, some will have fertilised a female before being caught so keep an eye out for baby caterpillars appearing on your hedges & plants and be ready to spray as necessary.

2018-08-22Kew Green, Richmond TW9 3AH, UK

I have had a two week period of less activity and fewer captures in my 4 traps. However over the past two nights I have seen a marked increase of captured moths. In fact each trap has collected over 30 moths each daily. Is this the start of the 3rd wave or the end of the second? One tip for all using traps is it is better to fill them with some water as without it the dead moths gather in the base and act as carrion for hundreds and hundreds of bluebottles !!

Note from EBTS UK: It's an interesting question wave 2 or 3 given it all gets a bit blurred by this point in the cycles, but currently I think we are probably still on the 2nd wave.

With regard water in the trap I've not found leaving it dry a problem as long as you empty the trap once a week. I did have a problem with foxes knocking the trap down to get at the water.

2018-08-21Churchfield, Harlow CM20 3DA, UK

Found 100s of caterpillar on six box hedges in front garden, cut hedges down and sprayed with appropriate pest killer, that was two weeks ago. Today 21/08/2018 my three box hedges in the back garden are covered in caterpillars, again trimmed and sprayed with per killer. Never knew about moth traps and never seen any moths.

2018-08-20Mereworth Road, Mereworth, Maidstone ME18 5JQ, UKBox moth caterpillars found by Head Gardener whilst cutting box hedging in private estate garden. Caterpillars were not visible until new box growth had been cut off and webbing was seen deeper into the hedges. Around 10 caterpillars were found on three separate hedges in close proximity, but the hedges are showing no major damage thus far and are otherwise healthy (treated regularly with fungicide as blight preventative and fed with TopBuxus). Will be treating with BT spray for rest of season and monitoring all box in the garden carefully for further signs of caterpillars.

2018-08-01Lady Margaret Road, London NW5 2NG, UK

Damage suddenly appeared in our garden and several other box in this street.

Note from EBTS UK:  Even with bushes looking that bad you would be surprised how it will most likely recover given water and some plant food - assuming it hasn't been allowed to totally dry out in the pot.  Some people cut their bushes back for aesthetic reasons, but the leaves will normally re-sprout on the existing branches as long as you don't mind the current rather sad look for a while.

2018-08-16Colebrooke Row, London N1 8AF, UKBox moth pheromone trap put up yesterday. Over 60 moths already in it
20018-08-16High Street, Olney MK46 4EF, UK

Update to my previous communication on 12th Aug . Our 150 year old+ box trees/bushes show localised signs of recent caterpillar damage. Yesterday I set up a box tree moth trap purchased from The Green Gardener with the Ginko Buxus Season Long pheromone lure - not caught any moths yet or seen any caterpillars - but I did speak to a local who has had his box hedges attacked by caterpillars and seen them. I am wondering if it is worth purchasing some Xentari at this point of the season? What is the shelf life of Xentari?

Note from EBTS UK:  I think it is around 2-3 years from production, I'm not sure whether after that is just stops working or becomes less effective (most likely).  Don't forget if you mix it up, you need to keep it in the dark away from sources of UV light as this will break it down.

Great picture of the caterpillar trying to hide behind the leaves having eaten others.

2018-08-16Slindon, Arundel, UK

Caterpillars found after devouring 3 of 8 buxus cubes. Will spray tomorrow once rain stops.

15/08/18Berkeley Avenue, Bexleyheath DA7 4UA, UK

Approximately 30 box moths caught in pheromone trap last night (back garden). This trap is hanging in a large tree about 7 foot up & equal distance between 3 medium sized box balls. I was going to lower it but have decided to leave it in place & maybe place another trap lower down too. Front garden trap empty.

2018-08-14Richmond Park Road, Kingston upon Thames KT2 6AF, UK

We have 5 small box balls in our front garden and only this year I have spotted the caterpillars.  I have been removing them by hand but have now resorted to spraying them with insecticide.  Today I also noticed two moths, so shall be investing in a trap.  Unfortunately I have noticed many neighbours decorative box in their gardens have been destroyed.

Note from EBTS UK:  If you can install a pheromone trap that will help both you and the gardens around you by disrupting breeding cycles in the area (sadly not 100% but it helps particularly if more people do it).  When looking for an insecticide make sure you are careful how you spray depending on the type you buy - many aren't friendly to bees and other garden beneficials.

Returned after holiday to find very unhappy 16-year old box tree. Took me some time to find out what was killing it … saw one caterpillar. Have ordered XenTari and will get spraying as soon as it arrives. Wish me luck!

2018-08-11Hambro Road, London SW16 6JE, UK2 hedges decimated. Found a couple of caterpillars but the damage was already done - in a short space of time. Sprayed them with Bug Clear
2018-08-13Haweswater Close, Bordon GU35 0LP, UK

1st spotted 2 adult moths on 25th June. Last week all my boxes were fine but today I noticed the start of activity. Picked off over 100 caterpillars so far - and sprayed the plants with Bug Clear. One poor plant had over 20 caterpillars. Have approx 50 box plants so will keep a careful eye on them - some are more chewed up than others 🙁

Note from EBTS UK:  It's a good idea to spray about 4 days after you see moths start to fly as their eggs hatch into caterpillars very quickly.  Then repeat spray 14 days later to catch any further caterpillars.

2018-08-13Woodland Rise, London N10 3UJ, UK

Came back from holidays to find my boxwood infested. Took off over 200 caterpillars by hand. Spraying with Pyrol bug and larvae killer. Will see about getting pheromone traps.

2018-08-15Tye Green, Elsenham, Bishop's Stortford CM22 6DY, UK

Came back from holiday to find two box cones had very little leaf at the top. on investigation I found caterpillars had eaten all leaf with lots of dead leaves at the base of the cone. Will cut out treat and feed, unfortunately due the the amount of damage the caterpillars have caused they are no longer cones! :+(

2018-08-11NW5 2PU

Neighbours alerted us to damage to box trees caused by the box moth. Several moths and one caterpillar seen. Sprayed with Bug Clear as recommended by garden centre but cannot reach tops of trees. Over what area is a pheromone trap effective?

Note from EBTS UK: Most of the pheromone lures used in the traps will cover anything about 7m from the trap which is around 180sqm.

2018-08-11Vellacotts, Broomfield, Chelmsford CM1 7EB, UK

1 Caterpillars and leaf damage to single topiaried pot specimen in back garden.

2 Caterpillars and the start of leaf damage in 12m of Buxus Sempivirens dwarf hedge in front garden. Started treatment with broad spectrum pyrethrum spray (make unknown). Trap on order.

2018-08-12Warwick CV34 6PD, UK

Devastation, overnight, on my two 40 year old topiaries. Caterpillars found++

Note from EBTS UK:  Don't give up if you spray with a suitable biological insecticide you will be able to control the caterpillars and with the addition of a pheromone trap help reduce the number of fertilised females that lay eggs.

Box is very resilient so it will almost certainly recover.

2018-08-10Edgefield Avenue, Barking IG11 9JN, UK

My 2, 10 year old low box edge plus 2 box balls have been stripped over a few days.  The advice I have been given due to the poor state of the plants is to dig them up and burn them.

Note from EBTS UK:  If you are prepared to give the bushes time to regrow and to treat them with a suitable spray, the bushes will almost certainly regrow - click HERE to take a look at some examples from South West London

2018-08-11Woodland Close, Benfleet SS7 2JH, UK

Found numerous caterpillars on our Buxus topiary trees.

2018-08-11Claremont Road, Surbiton KT6 4RH, UK

Just notice the catapillars on the Buxus and on further investiation the catapillars on are on 4 or 7 trees at the moment. One is very badly damaged and the other 3 are just corners at pressent. These are very old and established trees and shrubs.

Note from EBTS UK: Don't give up on them, they will almost certainly recover as long as you kill off the caterpillars with a suitable spray and do the same as soon as you see any further caterpillar damage.  It might also be worth feeding and watering the plants to give them a bit of a boost.

2018-08-11Woodland Close, Benfleet SS7 2JH, UK

Two bushes of buxus Green Velvet completely stripped bare of leaves. One bush of Buxus sempervirens had over twenty caterpillars and webbing. I cut out the damaged stems and cut up all the caterpillars. One bush in the shade not affected yet. Two moths seen.

2018-08-05Glencrofts, Hockley SS5 4GN, UK

4 caterpillars found and removed. Signs of previous damage found last year and eggs found 4 years ago but unsure what these were at the time. Not too bad considering I have 60+ balls, 38 cones and yards of hedging.

Caterpillars found on box cones and balls at nursery.  Old stock so has been infected here rather than imported.

2018-08-06Richmond TW10 7RS, UKHam House and Garden (National Trust). Second wave of adult moths spotted (approx 10). 11 pheromone traps refreshed with new lures.
2018-07-08Kew Green, Richmond TW9 3AH, UK

I have 4 traps One at the front of my house and 3 in my back garden Each of the traps are placed 100 feet apart and are strategically placed in or around where we have Box planted. Over the past few days I have seen a marked increase in moth activity I have caught (non specific Box moth type) Front garden 10 moths Top of back garden 18 moths Middle of garden 12 moths Bottom of garden 19 moths. I have also killed 6 moths that swarmed around the front garden light I think this signals another wave which maybe has been caused by the hot weather ? I have not seen any gtrace of caterpillar on any of my Box but I have now started to sray (5 litres) with XenTari every 10 days.

Note from EBTS UK:  Keep up the good work of trapping the moths.  You are right that we are seeing the start of another flight in parts of West London.  This means that eggs will start to be laid soon, followed by another wave of caterpillars at which point it will be time to start spraying again.  It shouldn`t be necessary to spray unless you can see signs of caterpillars activity or unless you are not going to be able to keep a regular eye on your plants.

2018-08-05Tower Avenue, Chelmsford CM1 2PW, UK

I noticed browning and dead leaves on my box hedge. On closer inspection I found caterpillars in cobwebs exactly like those pictured 🙁 This is the first year my hedges have had this problem.

2018-08-05Ruskin Walk, London SE24 9LZ, UK

While I was away caterpillars destroyed a long strip of box edging. No green leaves left.

Note from EBTS UK:  Don't give up, it's amazing how box will come back, even when it looks totally stripped.  As long as it hasn't totally dried out you will start to see green shoots again.  Try watering at the base and giving it some fertiliser.  If you aren't convinced have a look HERE Towards the bottom of the story are some pictures from Iain in Southfields, his hedge was attacked and came back fully to life.

2018-08-05Dennan Road, Surbiton KT6 7RY, UKTwo BuxaTraps installed in back garden.
2018-08-04Dennan Road, Surbiton KT6 7RY, UKSeveral caterpillars detected infesting our box hedges going round the garden. All killed off now.
2018-08-06Court Lane, London SE21 7EE, UK

Went away for a few days and returned to find lots of our box have been stripped and many more covered in caterpillars. We already have two traps in the garden that have caught many males since the beginning of the summer. Will pick of caterpillars and try spraying too.

Note from EBTS UK:  The pheromone traps are not 100% effective at trapping all the male moths so some females will be fertilised and as they can lay up to 700 eggs during their life time some will inevitably hatch and end up as hungry caterpillars.  It's still worth catching them though as it does reduce the size of the problem, so keep up the good work!

2018-08-05Harlescott Road, London SE15 3DA, UK

Just started to pick off caterpillars from three box plants. >30 from the first one alone so far. Not amused that wasps seem to be very interested in the squashed remains! This is our first experience of the problem here, so I'm searching for recommendations on the best pesticide to deal with it.

Note from EBTS UK:  Your box plants will recover so don't give up.  The most effective spray that targets only caterpillars (safe with bees and other garden beneficials) is XenTari.  The problem is it isn't licenced for domestic use in the UK (it is elsewhere in Europe etc), however there are many companies selling it online (including Topbuxus who have a link in the EBTS Shop).  Other insecticides do work, but generally less effectively and are not as safe around other beneficial garden insects.

2018-08-04Feltham TW14, UK

One 20 year old box bush completely eaten alive by caterpillars - only a few remaining green leaves. Other box bushes only slightly affected.

Note from EBTS UK:  Don't panic - unless the caterpillars have eaten the bark off the stems of the plants they will normally recover.  Take a look at the Box Moth & Caterpillar page on our website and purchase a suitable spray to deal with the caterpillars and keep an eye out for them again later in the year as there are usually 3 batches a year in the UK and we are currently on the second wave.

It's worth noting that the cost of replacing plants with alternatives will almost certainly be more than treating them when they are attacked by the caterpillars.

2018-08-04Ward Avenue, Cowes PO31 8AZ, UK

Caterpillar attack and total defoliation. Following advice, plants removed and destroyed.

Note from EBTS UK:  The advice you were given was incorrect, it is not normally necessary to take such extreme action.  Unless the caterpillars had eaten the bark off the stems, the plants will normally fully recover.

The cost of replacing with alternatives will almost certainly be more than treating them when they are attacked by the caterpillars.

2018-07-27Muncaster Road, London SW11 6NT, UK

Caterpillars on box topiary plants

2018-08-03Heathlee Road, London SE3 9HP, UK

Found caterpillars in Box in front and back garden. Picked off ones I could find, about 10. Sprayed with Xen Tari. Am a gardener by trade so aware what to look for, lots of gardens have the same problem locally. Traps/Spraying and informing clients what to look for. Seems much worse this year. Perhaps need to think about replacing with Ilex Crenata or similar.

Note from EBTS UK: It's definitely a good idea to inform your clients of the potential issues, but it's also important to point out that the alternatives won't give the same effect and that as long as they are willing to put in a little additional effort (or their gardeners effort) then it is possible to have good healthy box plants despite the caterpillars and moths. We have a handy 8 page booklet on the subject which we can send you just email with your details

2018-08-03Shepley Close, Carshalton SM5 2NJ, UK

2 20 years old boxes anhilated in a week, webbing and green poo pellets everywhere.

Note from EBTS UK: Don't give up, the bushes will recover even if they look quite bad. Spray to kill off the rest of the caterpillars and water & feed the plants at their base. New leaves will appear and if you keep an eye out for caterpillars in the future and take action as soon as possible your box will be around for another 20 years

2018-08-02Lynwood Road, Thames Ditton KT7 0DW, UK

Very substantial infestation of Moth tree caterpillar and pupae attacking 13 box balls and spirals in containers. 155 caterpillars and 6 pupae removed and destroyed on 2nd August 2018 followed by liberal spaying (750 ml) of Provado Ultimate Bug Killer in the evening. The following day, a further 32 caterpillars and 4 pupae were removed from 11 of the affected plants, which included just 3 dead, discoloured specimens which the spray had killed the previous night. Most of the survivors had already wrapped themselves in protective webbing and turned over leaves which the hand held spray could not penetrate. Given that the early stages of pupation has the larva looking just like a large Box leaf, they are difficult to spot and a significant number will now over winter and wreak damage next spring. It seems that there is much discussion of how to capture the adult moths and kill the larva but nothing on strategies for dealing with the pupae which are usually wrapped securely in rolled up leaves and webbing and impervious to chemical sprays. This does not look like a winnable long term battle...

Note from EBTS UK: Thanks very much for your detailed report.  At this time of year the pupae that have wrapped themselves in the leaves will be getting ready to change into the next batch of moths as there will be another generation before the overwintering or diapause begin and they do this, not as pupae, but as small larvae (caterpillars). So it is really important to kill off as many as possible before they enter diapause.

EBTS UK is working with a couple of companies on potential products for the future, that will help us all deal more easily and effectively with the problem,so keep an eye on the website for updates or sign up for our newsletter.

Found 100's of box tree caterpillars on young buxus hedging and topiary balls. Total destruction of plants on 7 days.

Note from EBTS UK:  Although it can feel like total destruction of your hedges and box balls, unless the caterpillars have eaten the bark off the plants, they will recover in a few months.  If you spray as soon as you see the caterpillars it is possible to have healthy boxwood hedges and topiary.   Our website has a number of suggestions for ways of dealing with the moths & caterpillars which I hope will help you deal with the situation - please don't give up on your box.

Caterpillars, eggs, leaf destruction.

Note from EBTS UK: Hi, it's more likely that the 'eggs' are actually frass (caterpillar excrement) as the eggs are very small and laid on the back of the leaves so aren't easy to see. 

2018-06-15Colne Road, Twickenham TW2 6QE, UK

A few caterpillars seen last year but many more in May this year. Put out 2 moth traps (us and the neighbour who also has box) Over 200 moths in 2 weeks caught but caterpillars have now reappeared end July now planning to spray Xen Tari

4 Buxatraps in garden but no new moths caught for a week or so now. Captured lots of moths at end of June/early July and also successfully tackled a large infestation of caterpillars in May. Looking out for caterpillar activity now but none seen yet. However there is cobwebbing but not sure if this is from spiders or caterpillars! Going on holiday shortly so will spray everything with xentari as a precaution before departure and ask neighbour to monitor whilst away.

Note from EBTS UK:  A spiders cob-webbing tends to be in one plane across the top or side of a hedge or between plants where as the caterpillars web is between leaves and in multiple directions.

All plants covered in eggs and caterpillars. Some plants have been completely stripped in a matter of days 🙁 Plan to spray today....

2018-07-22Alton GU34, UK

Hundreds removed by snipping off growths where damage found. 2nd brood this season I think. The best stage for control I think is soon after hatching only a few mm long with easily visible leaves where they have rasped the underside before they are big enough to chomp the leaf away. All at the same stage across 10 large isolated topiary mature trees. Following up with a spray and hopefully will eradicate this brood. Will look out for adults by disturbing trees from time to time.

Note from EBTS UK: You are right that the best time to deal with the caterpillars is as soon as there is visible evidence of activity, like that shown in your picture.   Depending on the spray you are using, you should keep an eye open for further activity a week or so later, as some of the eggs will hatch later than others and follow up spraying is likely to be necessary.

2018-07-18N7 8LS

Infestation of caterpillars which have shredded a large number of box plants. Now sprayed all of my box plants and hoping those damaged will recover.

2018-07-20Hillcross Avenue, Morden, Surrey SM4 4EG

70 moths captured with season long pheromone lure over the past month in a steady stream. But only a few over the past week!

Note from EBTS UK: This is normal for this point in the cycle. In a little over a month the moths will start to appear again when the caterpillars have changed into cacoons and then into moths.  Watch out now for the caterpillars as some females will almost certainly have laid eggs, so be ready and spray as soon as you see any eaten leaves or cobwebbing.

2018-07-17TN15 6RU

Moth on bathroom ceiling. As I currently have two operational but empty traps in my small garden I assume it’s a female.

Note from EBTS UK: Not sure if it is as there appears to be a slight bushiness to the tail which the female doesn't have.  The males seem to be able to fly round the lures quite a bit before they actually drop into the trap and they are easily distracted by lights.

2018-07-14TN15 6PT4 moths caught over 2 traps. Traps have been in position for 2 weeks.
2018-07-16Thornwood, Epping CM16 6LS, UK

5-6 weeks ago caterpillars pretty much destroyed my 6 large box balls. When I realised what was happening I sprayed ultra bug killer and picked them off but there were hundreds. Box slowly trying to come back and today gave noticed small moths again on box. Help.

Note from EBTS UK:  Unfortunately there are normally three repetitions a year of the caterpillars/moths so be ready with the spray again to deal with the caterpillars as soon as you spot any cobwebbing of the leave, little green balls of frass (caterpillar excrement) or small caterpillars.  If you want to use a better and safer spray, you could try XenTari which is available from Topbuxus via our website shop.  This is the most effective way to deal with them and it is safe around bees and other garden beneficial insects, unfortunately not available in UK shops yet so it has be ordered online.  You can help deal with the moths by installing a Buxatrap Pheromone Trap, just search online for the best deals - should be around £29ish.

Don't give up, as it will cost more to buy new plants than it will to spray 3 or 4 times a year to keep the problem under control.

11 moths altogether. (3 traps)

2018-07-03London N1 0FJ, UK

Bit of a disaster; usually we empty traps (x3) on fridays, however I was away and not emptied till following tuesday. Consequently the 2 wet traps were full of decomposed moths, flies and fly larvae; however the dry trap contained 57 bodies!

2018-07-14Speldhurst Road, London W4 1BZ, UK

Hedges all treated with XenTari and now caterpillar free with little damage done as it was caught early.

Second infestation this year

2018-07-11Richmond TW10 7RS, UK

Ham House Garden (National Trust) 16 adult moths caught in pheromone traps in last four weeks (11/06/2018 - 06/07/2018). We have approx 300m+ of low hedging and 80 large topiary cones.

Note from EBTS UK: Thanks very much for logging your sightings it's good to hear that proper monitoring is in place. The caterpillars are very active just down river in Chiswick so you will need to spray soon. It would be good to hear how you deal with caterpillars and whether you use a Bt based spray like Dipel (roughly £50 worth would cover the Ham House box), given its minimal affect on anything other than caterpillars.

2018-07-11Speldhurst Road, London W4 1BZ, UK

As the small caterpillars did not seem to have been affected by spraying them with 'SB Invigorator & Bug Killer' 24 hours after the initial spray, the plants & caterpillars have now been sprayed with XenTari so that no more damage is done.

2018-07-09Speldhurst Road, London W4 1BZ, UK

Small caterpillars found on a number of box plants (not surprising given the number of female moths seen fluttering around the plants).

Sprayed some individually potted plants with 'SB Plant Invigorator & Bug Killer' as suggested in the Financial Times - 8hrs after spraying the caterpillars were still alive - if they aren't dead by tomorrow they will be sprayed with ZenTari.

Sprayed front garden plants with ZenTari, but back garden will be treated with a new way of distributing nematodes as part of a Dutch trial I'm taking part in.

Went away in April for a month. Returned May to find all box hedges completely savaged. Spoke to RHS and local nursery and learnt about box caterpillar. Sprayed with Bayer product, 'combed' hedges of dead leaves and fed with fertiliser. Most of the hedging now has a lot of regrowth. Was recommended this site by garden pro on Houzz and purchased moth trap. Have continued to spray every 3 weeks and the moth trap has caught 12 moths caught in its first week.

EBTS UK was asked to look at the box in the Sunbury Walled Garden to see if there was any problem.  There was a little caterpillar damage, but generally the box appeared to be in excellent health. It was suggested that pheromone traps be installed as soon as possible and to keep an eye out for the next wave of caterpillars that will be coming soon.  The gardeners were also given some of the new 'Box Moth & Caterpillar, An EBTS Guide' for them to give out to visitors.

Having dealt with a fairly large infestation of caterpillars at end of May I have now caught first moths in two Buxa traps. Three moths so far..... how long before the next wave of caterpillars so I can be on alert? Really hope I don’t have to go through whole saga like last time with xentari as it took days!!!  My poor box (have a lot of it) is only starting to recover.

Note from EBTS UK: We'll need to start keeping an eye out for caterpillars in about 2-3 weeks time but it's no bad thing to check your box on a weekly basis for the signs of caterpillars.  At the first sign of activity spray again to nip the issue in the bud (it's recommend then to spray twice more at 7 day intervals so that all caterpillars are killed off - though you can also just spray any areas where there is signs of activity as long as you are vigilant).  Good luck and please don't give up on box or let the invader win.

Trap installed. Two moth after 48 hours. Two caterpillar seen last week.  70% leaf already eaten.

Note from EBTS UK:  Don't give up the box will grow back, just keep your eyes peeled for the caterpillars and take action as soon as you can - picking off or better still spraying with a safe caterpillar killer spray.

2018-06-13Speldhurst Road, London W4 1BZ, UK8 common box moths caught (6 in front garden and 2 in the back) + 5 Melanic box moths (4 in the front 1 in the back garden). Melanic box moths have darker wings.

Caught a moth in a trap on front balcony

2018-06-14Patshull Road, London NW5 2LE, UK

Catapillars seen and about 30 killed by hand and Buxatraps installed 10th May and sprayed with ZenTari.  About thirty moths in traps. Unfortunately foxes turned over traps and made off with top pheromone plug! So have started again.

Note from EBTS UK:  If you can, try hanging your trap higher up that way the foxes shouldn't get at it, but the moths will still be drawn to the pheromones.  If you haven't got anywhere suitable to hand the trap, the BuxaTraps also allow you to mount them on a bean pole - a meter off the ground should work fine.

2018-06-06Andover Road, Micheldever Station, Winchester SO21 3AY, UK8 Caterpillars found on box ball. Lots of webbing on plant. Caterpillars taken off by hand and webbing removed before clipping back.

Caterpillar infestation of box hedge - reduced 75% of hedge to stems. Initially picked them off but then cut down the box and burnt it all. (Front Garden of terraced house has box - found one caterpillar but evidence of more.)

Note from EBTS UK: I know it's a bit late to say it now, but you really didn't need to cut the hedge down as Box is brilliant at growing back, as it will from it's now reduced state.  The key thing is to deal with the caterpillars as soon as you see them by spraying with a suitable pesticide (preferably one that is safe for use with other garden beneficials).  Then add a pheromone trap to disrupt the breeding cycle of the moths and thus reduce the number of fertilised eggs that are laid.

Note from EBTS UK: Thanks for snapping a great picture, however if you see any more please help your neighbours who may have box by dispatching it quickly as this one is a female that could lay up to 700 eggs in her lifetime (males have a bushy tail at the end of their body).

2018-06-05Holyrood Rise, Bramley, Rotherham S66 3QE, UK

Noticed leaves being eaten on the 3rd June. 2 days later most leaves have holes and are going black.  Don't think this small bush will survive the week.

Note from EBTS UK: That doesn't look like box leaves, so I don't think it is box tree caterpillar that is eating the leaves.  The brown circular areas are where eggs have hatched and the insect has eaten the surrounding leaf.  I'm afraid I don't know what type of caterpillar it is in the picture is, but you could spray with an insecticide suitable for caterpillars - click HERE and scroll down "Getting Rid Of Caterpillars" for a list of different types you could use.  good luck helping the bush survive.

I have cut the tops off the Bush to remove the chrysalis. Bark looks ok.  The Bush looks dead as as doornail.  Spotted a moth this morning in the front garden.  Traps ordered.  Will not be defeated!

Note from EBTS UK:  Sounds like you may have used a slightly more drastic approach then may have been needed - spraying would have been a less invasive technique!  Still box is a remarkable plant when it comes to regrowth so fingers crossed you will get little green buds appearing on the stems that are left.  Good to hear your aren't giving up and get the trap out as soon as it arrives so that we can all reduce the number of fertilsed eggs that are laid.

Lots of fully grown caterpillars on my box, only found them when I noticed box dying, picked off about 7, and hoovered bush, worried about all my other hedges. will set up trap.

Note from EBTS UK: Definitely keep an eye on the other bushes and it might be worth spraying them so that any caterpillars that are hiding are killed off before doing too much damage

2018-05-30Deborah Crescent, Ruislip HA4 7TB, UK

Haven't found caterpillars but leaves eaten and lots of webbing and lots of what looks like sand on lots of leaves.

Note from EBTS UK: I've classed this as caterpillars as it sounds like they may now have changed into moths.  So it would be a good idea to install a pheromone trap to catch as many males as possible to reduce the number of fertilised eggs that are laid.

2018-05-12Compton Way, Farnham GU10 1QY, UK

All my box topiary and large box bushes are affected badly. Very concerned that plants won’t revive. Have sprayed with Bug Clear. Will re spray in another weeks time.

Note from EBTS UK:  As long as the caterpillars haven't eaten the bark from the stems your bushes will recover, just keep an eye out for caterpillars later in the year and act quickly to remove them (spraying or nematodes is really the only effective treatment for the caterpillars).  To reduce the numbers, install a pheromone trap to catch the male moths that are starting to fly now and this will reduce the number of fertilised eggs that are laid.

2018-05-24SL9 8HN4m long x 1m high 22 year old hedge completely defoliated in the space of 2 weeks. I must have removed 200+ caterpillars (using chopsticks) in one day. Another hedge partially colonised by the caterpillars. After removal, sprayed with Provado.

Hundreds swarming on our box hedge.

2018-05-28EN9 2SG

I have 30+ Box trees all different shapes and sizes every one of them is infested with caterpillars at the weekend I've probably removed up to 500.  I've now bought moth traps and about to spray them, absolutely gutted, had these for over 17 years.  I thought my wife would kill them first of all, when I asked her to cut them, as I was away, but when I put my glasses on and look closely, there they were.

2018-05-26RM14 3LP

Dozens of caterpillars found on 3 box balls, 4 box cubes in back garden and ours and neighbours hedges in front gardens. Webbing and defoliation appeared very quick. Have not sprayed with anything for many years but have reluctantly purchased Provado for Fruit and Veg.

Note from EBTS UK:  If you would rather not spray with Provado and use something less toxic to other insects, you could buy nematodes which are available from and if you use the link in our shop you can get 10% off your order.  You just water them onto the affected plants so that they make contact with the caterpillars and repeat three times.

2018-05-29TW9 3AH

I have 3 pheromone traps bought from the Green Garden Co with a season long lasting lure. All have been active for one week. Not caught a moth as yet. Box looking very healthy after 2 sprays with XenTari ( March and May ) and no attack so far this year. We had an NGS open garden this week with circa 500 visitors and displayed information regarding moth and caterpillar prevention.  We hold another open day next Sunday where we will do the same. We are pointing visitors to the EBTS website and the Green Gardener.  The more people that are made aware that there is a solution (many are not aware that there is a solution) the better chance we have to keep our Box hedging and topiary intact.

Note from EBTS UK:  It's great to get some good news and congratulations on your NGS open garden day, 500 people is a good turn out.  Also thank you very much for pointing people at the EBTS UK website and letting your visitors know it doesn't have to be the end of their box plants if the caterpillars do strike and it is possible to fend them off.

20+ caterpillars found on two small pyramid shaped box trees.

2018-04-15Reynolds Road, London W4 5AR, UK

My hedge has been completely eaten within about a day.  I had not been aware of this caterpillar.  I sprayed the hedge with what I had to hand and it is now recovering.

Note from EBTS UK:  Good to hear it sounds like things are under control.  It would be a good idea to put out a pheromone trap to catch as many male moths as possible and thus reduce the number of fertilised eggs that will get laid.

Sadly there are likely to be two more rounds of caterpillars this year, but if you spray as soon as you spot activity, it is perfectly possible to keep your box looking good.

If you haven't already checked out the details of the various options for spraying and nematodes take a look HERE

Webbing, leaf damage, and 3cm caterpillar found on Buxus sphere in garden. Spraying with Bandu next week. (I have a spray licence).

2018-05-28CO13 9JS

Found box moth caterpillars on my box hedging. Have sent for nematodes to try and reduce the damage. The sparrows are very good at finding the caterpillars and eating them.

Note from EBTS UK:  It's interesting to hear that the sparrows are eating the caterpillars as normally they try one and don't like the taste as they are mildly toxic - it would be great if they have acquired a liking for the caterpillars though!

2018-05-21CM16 4PXBox hedge badly infested with the caterpillars.
2018-05-28AL3 7JX

Metres of lovely box hedge eaten in past week. Only just discovered what it is and need to act quickly.  Garden due to be open to public in 3 weeks.  Still researching but all advice welcome.

Note from EBTS UK: Spray with a biological insecticide (see HERE for suggestions on what to do) or apply nematodes.  Then comb through the bushes to remove the debris and cob-webbing using a sheet under the plants as you do it to help collect the bits that fall out.  Also water your plants at their bases if the ground is dry as after being attacked they will dehydrate through the eaten leaves.

When you open your garden make sure you explain to people that with the use of safe spraying and pheromone traps we can still enjoy our box plants as long as we keep a watchful eye on them at key times of the year.  Also feel free to point them at the EBTS UK website for further info!

Thanks for adding a marker and good luck with the garden opening.

Trap. Minimal sightings (all removed by hand)

2018-05-27Alexandra Park Road, London N22 7BJ, UK

Over a hundred caterpillars demolished hedge in a day.

Note from EBTS UK: Although it will feel like the caterpillars eat the hedge in a day, they will have been chomping away for a couple of days or more as they start from the inside working their way out.  So it's important to keep an eye out for the tell tale signs of webbing, what appears to be reduced leaf growth and little balls of green frass under the hedge when you lightly brush the bush.

Key thing is, don't give up, keep removing the caterpillars - you will have better success with a biological insecticide (but make sure you choose a bee friendly one) than picking them off by hand.

2018-05-27W4 1BZ

***1st Moth Caught in front garden trap*** This means that within a few days eggs will start to be laid on our box bushes so we need to catch as many male moths as possible in pheromone traps to stop them fertilising the females.

Thousands of caterpillars found on our box hedges. Have cut two hedges down to a couple of inches to see if they grow back and have sprayed the other hedge with XenTari Raupenfrei and plan to cut back in a couple of days but not so drastically.

Note from EBTS UK: The XenTari should sort them out, once the caterpillars are dead, comb through the plant to remove the debris and then respray at the first signs of trouble. Also setup a suitable number of pheromone traps to reduce the number of male moths. Let us know how you get on

Finally had to admit defeat to these caterpillars after three years.None of the treatments have worked and have had to dig up all twenty bushes and burn them.

2018-05-25E17 8AQThis is the first year this pest has invaded my box topiary in Walthamstow, East London. One large plant totally decimated, all foliage gone, now bark in the process of being stripped. I have removed it. The other four plants I think I have caught in time and have been able to hand pick off the caterpillars and webbing. Our local borough council does not seem to be aware of the insect. I will be checking the remaining plants most days and removing any signs of life I find.

2018-05-23CM1 7DROne lot of Box at the bottom of the garden is affected but the others near the house are not at present. I'm guessing its just a matter of time. We've lived here nearly 6 years and this is the first time our box has been affected.
2018-05-24Warner Close, Slough SL1 5LZ, UK

My box trees (balls) look like locust have hit them overnight! Looks like spiders webs all over and all leaves eaten and catapillers all over.

Note from EBTS UK: Best thing to do is spray the box balls with a biological pesticide (see our page on Box Moth & Caterpillar for lots of info about the options) and put out a pheromone trap to reduce the number of male moths around to fertilise the females.

2018-24-5Empress Avenue, London E12 5HW, UK

Bayer Garden Ultimate Fruit & Veg big killer applied twice, appears to be useless ☹️

Note from EBTS UK: XenTari does appear to work quicker and more reliably but it is only available via the internet as it isn't licenced for sale for domestic use in the UK yet.

20/05/2018N5 2BE

Roof terrace - one box plant (only) with some evidence of Box Moth. Treated with XenTari.

Note from EBTS UK: Could you be more specific about the evidence of Box Moth - did you see the moth or eggs? Or was it evidence of the caterpillar i.e. cobwebs, frass (little green balls of excrement) and eaten leaves?  Just add another marker with the details if you get the chance - thanks.

Caterpillars. Some of my boxes were decimated last year. Others that weren’t quite so bad I cut back very hard and they started to look healthy this spring. Now, suddenly, within a couple of days they look shocking

Definitely Box Moth. Devastating our topiary trees.

2018-05-20N1 4HGWas warned by email from neighbours that box moths were in the area and on returning from holiday discovered parterre in front garden and 4 box balls in rear garden were all infested with caterpillars and covered in webbing. Only one ball (in sunniest location) very badly affected for now, others partially eaten. Not noticed caterpillars on the box before, but with hindsight there was potentially webbing present last year. Sprayed extensively with Provado this morning and Topbuxus XenTari and 2x Dragonfli pheromone traps on order in hope that it can be halted and the box recovered.

Severe infestation - 2m long hedge, completely defoliated, with over 1000 caterpillars removed in 3 days.  Plenty more still to get.

Note from EBTS UK: With such a severe infestation spraying will be the best way to bring this under control - options are listed on our Box Moth & Caterpillar page.  As the moths are about to start their first flights of the year, it would also be a good idea to install a pheromone trap to catch as many males as possible and thus reduce the number of fertilised eggs that are laid.

Webbing, eaten leaves and caterpillars discovered on all box in garden including topiary balls, cubes and cones plus 5 low level sections of hedging. No box plant was untouched!  Immediately hand picked around 100 caterpillars and then next day sprayed everything liberally with XenTari.  I have just repeated the Xentari spray one week later and discovered just a few caterpillars and some dead ones also.  I have set up 3 pheromone traps but no moths have been caught as yet.  Fortunately the damage is not too severe and hope I caught it in time.  Heartbreaking!

2018-05-16W3 6SS

Over three days at least 40 caterpillars removed from 7 box balls in pots.  The most vigorous bush suffered worst attack. The one in the shade was untouched.  I have one bad lung, is Provado spray safe for me and bees?

Note from EBTS UK:  It is possible that the one in the shade is infected, but because it is in a cooler location the caterpillars haven't developed yet - this has been observed in a North facing shaded Islington garden - keep an eye on it just in case.

Sprays: You should always be very careful, reading fully the instruction before  using them (I always wear a mask to reduce risks even if it doesn't mention it) .  With regard you particular situation I'm afraid we are not qualified to give you guidance.  Try calling the Bayer Advice line on 0845 345 4100

Bees - Provado Ultimate Bug Killer is dangerous to bees.  Do not use where bees are actively foraging.  It is also a risk to non-target insects and other arthropods.  Alternative biological insecticides that are Bee friendly are available online such as those based on Bacillus Thuringiensis like XenTari & Dipel.

2018-05-16Gloucester Avenue, London NW1 7AU, UK

All the lovely new growth on my two box balls in planters has been eaten, and today I found four of these dreaded caterpillars ( and noted some webbing).

2018-05-16Enfield EN1, UK

Garden hedges overwhelmed with caterpillars. Picked off 100+ in a small part of the hedge and the damage seems to be rapidly spreading through the garden.

Note from EBTS UK: When you get a large infestation like this it is important to spray to kill the caterpillars before they start eating the bark on the plants (they do this when they run out of leaves to eat).  If the bark is eaten then the plant are unlikely to survive, whereas if it is only the leave they will grow back.

2018-05-13EN1 1QE

Small box hedge surrounding veg patch infested with caterpillars picking them off but losing the battle.

Note from EBTS UK: Please don't give up, there are sprays that you can apply that are safe near vegetables and OK with Bees & other garden insects (but not caterpillars).

2018-05-15W3 6PD

Numerous caterpillars found after warnings posted on “next door”. Will order XenTari now.

2018-05-15SE5 8RF

My 30-year-old box tree was infested with caterpillars and webs when I checked it today.  At first I thought it might be box blight, but after spraying the tree with Provado Bug Clear Ultra I noticed several caterpillars were hanging from the branches.  Three small box balls which were fine a few weeks ago were also infested and each had several caterpillars visible.  This is the first year I have had a problem with the box trees.

Note from EBTS UK: Glad you have found the pests and are dealing with them, suggest you also purchase a pheromone trap to catch as many of the male moths when they start appearing in the next week or so.

2018-05-15KT11 2PG

Just found caterpillars on all our boxes.  None there 1 week ago, but one totally devoured already.  Going to garden centre to buy treatment immediately.

Got the kids to pick off the big fat caterpillars, but too many causing obvious patches in the hedge so sprayed today and will add a trap ready for the moths.

2018-05-14W4 1BZ

Box hedges looked really good so far, but just spotted a couple of caterpillars, so removed and sprayed the hedges - still very happy with late spraying last year that has meant very few caterpillars to deal with so far compared to other hedges in the neighbourhood.

Pheromone traps are out in both front & back gardens, so far no moths but it is only a matter of time as the caterpillars are huge, slow and beginning to wrap themselves in webbing so they are about to change into moths.

Caterpillars attacked box in both front and back garden in July 2017. Sprayed with Provado Bug Clear Ultra and put up Buxatrap pheromone traps. Repeated spray in September. No caterpillars seen again but very many moths trapped. Moths living in yew topaiary and ivy on neighbour’s fence so housed regularly to disturb them. In autumn fed soil around box with EM Growbest to boost strength of plants, and in early April sprayed all box with Effective Micro organisms. Box very healthy with regrowth from damaged areas. In May 2018 sprayed with Provado and renewed pheremone lures - no moths or caterpillars seen so far on our own box but very high levels of caterpillar attack on box in all neighbouring streets. Will shortly spray with Topbuxus Health Mix and then will respray with Provado in early June and renew lures.

Major infestation in box balls and box border hedge.  At least 50-60 in box balls and 150 in box hedge measuring 5 metres in length. I have removed as many as I can find by hand over last 7 days.

Message from EBTS UK: Recommend spraying to make sure you eradicate the rest biological pesticide such as XenTari is most effective + install pheromone trap(s) as appropriate for the size of your garden.

2018-05-10NW5 4HY

Two box hedges completed destroyed.  Came back after the bank holiday to find the hedges under attack.  Haven’t scraped yet but will do so ASAP.

Note from EBTS UK: Although the hedges may looked 'destroyed' they will almodt certainly grow back if you can get rid of the caterpillars by spraying and combing out the debris. 

2018-05-09SL8 5BZ

Numerous caterpillars seen today first time this year in my box parterre (also last year but kept under control by Provado bug clear).

Major caterpillar activity in our road - neighbours box hedge 1m x 3m destroyed last year and now going through our hedge - 200+ picked off last 2 days.  Other significant activity in Chiswick area.

Note from EBTS UK: Hope you are going to spray soon to stop those caterpillars eating your hedge - it will be more effective than trying to pick them off by hand and if you use XenTari it won't harm bees and other insects in your garden (unless they are caterpillars).

2018-05-08Zwanenburg, Netherlands

This is my mom’s house and the garden is side to side only separated by a brick wall but still all covered with shrubbery of many gardens of other houses. On first glance I could see dozens, but with further inspections there are seemingly hundreds all swarmed in the box plants. They are all surrounded by small strands of web/silk and are eating their hearts out and probably preparing for cocooning stage anytime soon. Some even seem to explore the common ivy and take a few bites out of that but are centered on the box plant, having ravaged most of the external leaves.

Note from EBTS UK: Location updated based on further investigation suggesting it was most likely to be in the Netherlands.  Thanks to Martin from Canada for suggesting this location.

Second season of infestation but this year we are on top of it as we now know what to expect and look for. A lot of the neighberhood are suffering with many box plants already lost. We are now spraying with Xen Tari twice a month

2018-05-02CM16 7BD

Box hedge not looking too healthy, on closer inspection lots of caterpillars and webbing found.  Looks like they have eaten the box hedge from the inside out and from the bottom up, still lots of new growth on the top of the hedge.  Just researching how to deal with the problem.

Note from EBTS UK: Most effective way to deal with the caterpillars is by spraying with a Bacillus thuringiensis based biological insecticide (safe with bees and other garden beneficial insects) such as XenTari (available from Topbuxus via our shop).  Good luck with sorting the problem out and we would suggest investing in a pheromone trap (or more depending on the size of your garden) as the moths will be appearing anytime now.

Several caterpillars located and destroyed.  This is on top of an infestation last year.  Have reinstalled the traps.

2018-04-08EN8 0TNFound lots of caterpillars on my box plants which is my hedge in my front garden. Think it has already taken approx half a metre down to the bark so am doubtful that will recover but shall be investigating what it is I need to use to kills these off. So annoying.

Caterpillars found on large box hedge. Removed by hand, but looks like lots of webbing so more to come.

2018-05-07NW6 6BJ

Got hundreds of caterpillars on my box. Picked most off.

Note from EBTS UK: Suggest you use a spray like XenTari to kill the caterpillars off as it is almost impossible to get all of them by picking them off.  You should also consider getting a pheromone trap as we are now at the point were the moths will start flying and laying eggs, so anything we can do to reduce the number of fertilised eggs that are laid the better (the traps catch the males so they can't fertilse the females).

2018-05-07SL1 2DEAt least 100 caterpillars on 6 box shrubs. Trying to remove by hand. Shrubs survived similar in 2017
2018-05-07KT14 6PN

Box eaten leaves, small patches of white stuff where the eggs are.  Green caterpillars found in box.

2018-05-06E18 1PN

Box tree completely infected. The caterpillars have even spread to the facade of the garage and of the house. We treated it with spray. We also witnessed one other garden in the Wanstead-South Woodford area where the box tree had the same issue.

2018-05-07KT2 7SZCaterpiallars found in all pots containing box, and in front garden box hedge. Killed approx 10-20 per pot. Catapillars in early stage some still in cocoon. Spraying xen tari tonight formthe first time and have ordered special moth traps for the garden.

Found caterpillars on hedges. Will get spray tomorrow and treat. 

2018-05-09SW19 3LA

My two small box ball tubs heavily infested with these caterpillars. removed 25-30. 

2018-05-05Cavendish Road, London SW12 0BH, UK

Many caterpillars observed on a box hedge in a private front garden


Several box affected.  Noticed the sticky white mesh a few weeks back. Wondered why the birds were paying so much attention to these box plants only to realise they were having their breakfast, lunch and dinner from them. Spent a few hours picking them off today but there are way too many to keep up. Will spray tomorrow. Hopefully they will recover.

Note from EBTS UK: Would be very interested to hear what type of bird was eating the caterpillars as most don't like the taste.  Good luck and in most cases box will recover well as long as the caterpillars haven't eaten the bark on the stems.

2018-05-05SW14 8RD

Whilst trying to dig out a dead box bush I noticed lots of caterpillars. 

2018-05-02CM16 5DL

Caterpillars found in large box bush. Caterpillar removed and destroyed, bush sprayed with XenTari.

2018-05-05SM5 1TD

Box completely destroyed.

Note from EBTS UK: Even though your box might look totally eaten, as long as the caterpillars haven't eaten the bark on the stems it will recover.  

2018-04-20E14 6PD

A lot of caterpillars on box bush.  Had infestation last year.  I kill over 20 caterpillars a day but it seems never ending.  I think I will destroy the box as it is too damaged after consistent attacks.  I saw moths in 2017.

Note from EBTS UK:  Picking off the caterpillars by hand is an arduous & not very effective control, as you have found.  It is best to spray with XenTari and install a pheromone trap for the moths.  It's always sad to lose box from your garden, so bear in mind that most plants will survive if you can control the caterpillars.

Trap installed in courtyard garden - no sign of caterpillars or at least that was what we thought - closer inspection showed they hadn't woken up yet as the courtyard location is still quite cold and doesn't get the sun.  They will be sprayed with XenTari.

Caterpillars eating box hedges around the Cromwell Hospital - spoke to the gardener and they are going to get the hedges sprayed before to much damage is done.

2018-04-24W4 1HT

One garden actively managing the problem and preparing for the future with a pheromone trap.

Spoke to another household, pointed out the caterpillars and they are going to get the gardener to deal with the problem.

2018-04-24SW5 0RACaterpillars have eaten most of the leaves on the hedge. If it is fed and watered (around the base) it will recover. In future the caterpillars need to be sprayed as soon as they are spotted and a pheromone trap should be installed to catch as many male moths as possible.

4 traps in one acre area of box hedging and balls

2018-04-17W4 1BZ

Trap bought from setup in back garden - this type has water in the bottom of the trap (adding a drop of washing up liquid reduces the surface tension on the water which helps trap the moths).

Installed one of the new Long Life Lure which last a whole season of 240 days. The lures are available from

No sign of caterpillars so far.
