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.

Title Address Description
2018-07-22Alton GU34, UKHundreds 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.

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. 

2018-07-20NW5 2XH

BUXAtrap installed in rear garden using syringe type pheromone lure. Caterpillars devastated one of six box bushes overnight early in June, since when have sprayed all bushes regularly with XenTari and have caught dozens of moths in the trap.

2018-07-01Altwood Road, Maidenhead SL6 4PZ, UK

Found large numbers of caterpillars on box plants. Installed a Buxatrap and have had 10 dead moths.

2018-07-16Friern Road, London SE22 0AU, UK

Caterpillars found on box hedging, sprayed with Resolver Bug Killer. Approximately 35 caterpillars destroyed.

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.

2018-07-14London N1 0FJ, UK

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.

Will keep an eye out over the next couple of weeks for any caterpillars that appear from remaining eggs, but hopefully that is it until the final batch in September/October.

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.

2018-07-11Ravenshaw Street, London NW6 1NP, UK
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.

Severe damage to 6 Buxus and slight damage to 2 others earlier this year. Now recovering very well with the use of XenTari and TopBuxus. Trap set last night with Ginko Buxus season long pheromone lure and I score my first victim on the first day!

2018-06-15Sunbury-on-Thames TW16 6AB, UK

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.

2018-06-18SW19 3DT15 year old box hedge in garden part-devastated by box-bush caterpillar. Removed approx two thousand by hand during May 2018. Following that, in June 2018 I began removing chrysalis, approx three hundred to date. Also removed approx fifty actual moths during June 2018. The hedge is now recovering well with lots of new growth.

2018-06-14Ringwood Way, London N21 2QY, UK

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.

Damage to hedges (both front & rear garden) over the last year or two - assumed to be cats spraying - possibly due to caterpillars though.
2018-06-11Lincoln Green, Chichester PO19 5DN, UK

Flew into the lounge last night and rested on the wall all day. Photographed and released. I do not have any box hedges.

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.

Box tree moth pheromone trap. Removed caterpillars weekly by hand.

2018-06-02Humber Road, London SE3 7LT, UK

Caterpillars spotted a couple of weeks ago and damage not too bad. But left them and in two weeks they have decimated box hedge in front and back gardens. 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.

2018-05-31Grosvenor Road, Richmond TW10 6PB, UKCaterpillar activity.
31-05-18Eamont Close, Ruislip HA4 7YX, UK

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.

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.

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.

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.
2018/5/24SL1 5LZ

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

2018-05-20CM16 7AB

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.

Note from EBTS UK: Thanks for spreading the word with your neighbours

2018-05-14W4 1HG

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.

2018-05-15SW16 6TZ

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.

Caterpillars eaten all my box trees and balls.

Message from EBTS UK: Don't give up, spray with XenTari & setup a pheromone trap (if you haven't already) and spray again if you spot any re-infection.

2018-05-11IG8 7BY

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

Nearly 40 caterpillars found on one topiary box and quickly disposed of! All evidence of larvae removed by hand; the plant will recover as infestation caught quickly. Daily monitoring to ensure no more outbreaks for spread to other box nearby.

2018-05-10N7 8LSFound evidence of some caterpillar damage and silk casings near base of my box hedging today, and one live caterpillar. Sprayed immediately with a garden insecticide. I know what to look out for now having had a very bad infestation a few years ago from which I am pleased to say all my plants recovered even though some looked very sick.
2018-05-10SW20 9AJ

Removed 76 caterpillars from single buxus hedge. Sprayed all hedges with garden centre insecticide. Parterre damaged and ball hedges stripped bare. Would describe as very bad infestation.

2018-05-09W12 9PG

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).

2018-05-09W4 3HA

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).

2018-05-081160 PA

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:  Please can you email us your address so we can confirm the correct location of the marker?

2018-05-05TW9 3AH

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.

2018-04-29SW9 9RT

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.
2018-05-07SW19 3ND

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

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.

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

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.

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

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

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.

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.

Trap installed in front garden.  This one from SBM Life Science Ltd, a BuxaTrap with the pheromone lure supplied as a gel in a syringe.  It will be interesting to see how it compares to the Long Life Lure in the back garden.
