The best Box tree moth traps, compared.
Top pick: Vitax Buxus moth trap refill Best value: SWISSINNO box tree moth trap – Cheapest kit at about £15.37, under £17. The lure count and lure life are unstated, and the star line is 2.9 from 12 reviews. Updated October 2026.
A box tree moth trap is a reusable funnel or clear casing hung beside box (Buxus). A pheromone lure draws male box tree moths into a little water. In the UK you use it to see whether males are flying. It does not clear caterpillars already in the leaves. A full catch is a warning. An empty week is inconclusive, because females ready to lay are not attracted. A suitable trap has a reusable body, a lure count the title and the bullets agree on, and a stated life of about four to eight weeks. Sachets only help if you already own a cage. The lure is for box tree moth, not clothes moths or pantry moths, and it does not belong in a wardrobe. A figure such as 180 square metres is seller wording, not a British Standard. Keep the foil on until fitting, and keep the water away from children, dogs and hedgehogs. How to tell a kit from a refill is in the [box tree moth trap buying guide](/hub/pest-control/box-tree-moth-trap/sub/box-tree-moth-trap-buying-guide).

Personal buying guide
Question 1 of 2
What are you buying?
Vitax’s Buxus moth trap refill is two lures at £10.99, about 10 g, with 4.3 from 88 amazon.co.uk reviews. The saved listing does not state how many weeks each lure lasts. Buyers who already run a trap say they catch a lot and that the odd moth still gets through to the hedge. One repeat customer reports a later pair of purchases that seemed empty compared with a year that had worked well. There is no trap body in the pack. The page leaves the target pest, the instructions, and indoor use as unanswered questions. It is the cheapest refill in this set if your cage is already on the hedge and you can accept a two-sachet pack with no weeks printed. It does nothing on its own if you have nowhere to hang a lure.
Pros
Cons
Best for: A two-lure top-up when you already own a Vitax-style trap and can check the weeks on the sheet in the pack.
Less suitable: A first purchase with no trap body, or a season that needs four sachets in one order.
Specifications
Common questions
Does this pack include a trap?
No. It is two lures at about £10.99, about 10 g. You need a cage already on the hedge.
How many weeks does each lure last?
The saved listing does not state a life in weeks. Check the sheet in the pack. A separate Vitax note has used 1–2 cm of water, which is a hang detail, not a lure life.
BuxusPro’s BuxTrap is a refillable box tree moth trap at £16.99 with four lures stated at four to six weeks. The listing tells you to hang it about 1–1.5 m up with about 5 cm of water and a drop of detergent, and to replace the lure about every six weeks. It is 4.2 from 146 reviews, the stronger large-sample star line among the bodies, and it does not carry the badge. Reviewers call the plastic flimsy and the instructions missing — one used a video — then describe a blank first week followed by over 100 moths in a warm week, or three to 18 a night once the weather lifted. A cooler spell produced nothing for three weeks. That score is not a garden trial, and this trap does not carry a badge. Buy it as a light trap body with four lures, not as a bag of sachets.
Pros
Cons
Best for: A first funnel under £17 when you want four lures and will accept a light plastic build.
Less suitable: You already own a cage and only wanted sachets, or you need a heavy bucket for a windy site.
Specifications
Common questions
Is this a bag of lures or a trap?
It is a refillable trap at about £16.99 with four lures. The listing says to hang it about 1–1.5 m up with about 5 cm of water and a drop of detergent.
Why is the star line strong without a badge?
4.2 from 146 reviews is the stronger large-sample star line among the bodies. The badge still sits on a different kit. This trap does not carry one.
PlantPro’s BuxAllure is four pheromone lures at £12.99, each stated at four to six weeks, with 4.1 from 77 amazon.co.uk reviews. The bullets describe attracting adult male box tree moths from the start of the overwintering flight, and there is no trap body in the pack. One buyer who caught nothing on small pellets switched and reports nine moths within a few days; another counts about 40–50 a week at the peak. A critic with box a few feet away caught none, after a different brand had worked on the same plants. A public specification line has also said three pieces while the bullets say four, so count the foil before you work out a price per lure. It suits an existing cage in the £13 band. Skip it if you have no trap.
Pros
Cons
Best for: An existing lure cage when you want a four-pack near £13 and will count the sachets.
Less suitable: A first trap, or a strict unit-price sum while the piece count is in conflict.
Specifications
Common questions
Does BuxAllure include a trap body?
No. It is pheromone lures only, stated at four to six weeks, about £12.99. You need a cage already.
Are there three pieces or four?
The bullets say four. A public specification line has said three. Count the foil before you calculate a price per lure.
PlantPro’s refillable trap is £18.99 with four lures, the bullets saying four to six weeks, with six weeks also printed, model 2057-4, about 240 g, country of origin the United Kingdom. The listing describes a clear casing you hang and reuse for several seasons. It is 4.1 from 56 reviews. Buyers who nearly returned it as flimsy later report catches after an afternoon of hand-picking; others had no moths in a second year. The video, reviewers say, never settles whether the vial lids stay on, and detergent in the water is easy to miss. One notes eggs still laid on the plant, which is what a male-only lure allows. Choose it when you want a four-lure body near £19 and will follow a leaflet the page does not print.
Pros
Cons
Best for: A four-lure clear trap near £19 when you will add detergent yourself and not treat the row as sachets only.
Less suitable: Someone who already owns a body and only wanted refills, or who needs printed instructions in the box.
Specifications
Common questions
Is this lures only?
No. The listing is a refillable trap with four lures and a clear casing, about £18.99 and about 240 g. It is not a sachet-only pack.
Do the vial lids come off?
Reviewers say the video never settles whether the vial lids stay on. Follow the leaflet if one is in the parcel, and add detergent to the water.
Russell IPM’s bucket, sold as IPM Direct, is £19.99 and about 364 g, with three lures the bullets say stay active for four to six weeks. It scores 4.0 from 91 amazon.co.uk reviews. Buyers who caught moths describe a green mesh basket, water and a dash of washing-up liquid, and one first night of about 16 moths beside a box plant they had also sprayed. Several say the parcel arrived without instructions, and one says to leave the lure cap on rather than opening it. A minority call the trap a waste of money. The bullets also mention indoor trapping, which is the wrong place for a box-hedge monitor and a different insect from a clothes moth. It suits a water-bucket routine if you will look up how to hang it.
Pros
Cons
Best for: A water-bucket monitor beside a hedge when you are happy to add a few centimetres of water and detergent yourself.
Less suitable: Indoor clothes-moth control, or a buyer who will not hang anything until a printed leaflet is in the parcel.
Specifications
Common questions
Can this bucket be used indoors for clothes moths?
No. Indoor wording on the listing is the wrong place for a box-hedge monitor, and a box tree moth lure is a different insect from a clothes moth.
Do the instructions come in the box?
Several buyers say the parcel arrived without instructions. One says to leave the lure cap on rather than opening it. Follow a leaflet if one is present.
IPM Direct’s pheromone refill is £12.99 with 3.9 from 157 reviews, the largest refill sample in this table. The title says a pack of four and another line on the listing says three, so do not divide the price into a firm cost per lure until you count the sachets. The listing states four to six weeks, with an April-to-October window. Reviewers describe quiet weeks and then a pot that fills overnight, including on a large box that had already been stripped one year. The saved bullets are mostly unanswered questions, so fit with every cage is not shown. It is a sensible spare if you already use an IPM-style basket and you check the count on arrival. It is the wrong parcel if you still need the bucket.
Pros
Cons
Best for: Spare lures for an IPM-style cage you already hang, once you have counted the sachets in the envelope.
Less suitable: A first monitor, or a unit-price comparison that needs an agreed pack count.
Specifications
Common questions
Is the pack three lures or four?
The title says a pack of four. Another line says three. Count the sachets before you work out a price per lure. There is no trap body in the pack.
Will these fit every cage?
The page leaves compatibility questions unanswered. They are a spare for an IPM-style basket you already hang, after you have counted the sachets.
BuxusPro’s BuxPhero is four lures at £11.99, each claimed for up to eight weeks, with storage below 30°C in the original pack. Only 11 reviews support the 3.9 star line. One household says the traps work in bursts and that they still change refills about every six weeks, which is shorter than the eight-week bullet. Another verified review says no results were seen. The page asks whether the lure works with all moth traps and does not answer. On a clean four-count the shelf price is about £3 a lure, the lowest printed unit price among packs whose count is not in conflict, and the sample is too small to treat that as proof of a longer life. Buy it for a cage you already trust, and follow the weeks on your own leaflet if they say six.
Pros
Cons
Best for: A low-cost four-pack for a BuxusPro-style cage when you accept a thin review sample.
Less suitable: A first trap, or a buyer who needs the eight-week claim backed by more than 11 reviews.
Specifications
Common questions
Do the lures last eight weeks?
The listing claims up to eight weeks. One household still changes them about every six weeks. With 11 reviews, that claim is not a large-sample result. Follow your leaflet if it says six.
Is there a trap in the pack?
No. Four lures at about £11.99, about 10 g. Store them below 30°C in the original packaging, and hang them in a cage you already trust.
No More Mr Nice Guy’s funnel is £24.98 with one trap and four lures the instructions say to change every five weeks, which the title calls a five-month supply. You add about 3 cm of water plus washing-up liquid, lock the funnel, hang the cage in the lid, and set the trap at 1.5–2 m, checking at least twice a week. The seller density is one trap per half an acre, about 2,000 m², which is far wider than the 180 m² lines elsewhere and is not a British Standard. Only 14 reviews sit behind the 3.8 star line. One buyer calls it fully successful; another asks why five months of lure when a March-to-October window is nearer seven. The assembly steps on the page are unusually complete. The thin sample and the half-acre line are the reasons to skip it for an ordinary garden hedge.
Pros
Cons
Best for: A buyer who wants the assembly steps printed on the amazon page and will ignore the half-acre claim.
Less suitable: A small hedge where £25 and 14 reviews are a weak reason to skip the larger samples under £20.
Specifications
Common questions
What water depth does the listing give?
About 3 cm of water plus washing-up liquid, with the trap at 1.5–2 m and a check at least twice a week. The lures are changed every five weeks.
Does one trap cover half an acre?
The seller line is one trap per half an acre, about 2,000 m². That is not a British Standard. Treat it as wording, not a tested radius.
The IPM Direct clear-casing trap is listed at £18.99 on amazon.co.uk, about 10 × 22 cm and 320 g, with 3.7 from 290 reviews, the largest sample among these kits. The title says three pheromone lures, while a feature bullet says four, each active for about four to six weeks, so count the sachets when the box arrives. Reviewers with established box describe a fiddly build and a quiet start, then moths once the trap sits in or against the bush, and one still picked hundreds of caterpillars by hand. Another update reports not a single moth after several nights beside an infected bush and a return. The technical row flags the trap as electric even though it is a passive monitor with no mains plug. It is the top pick here for review depth and a reusable body under £20, and a full catch still leaves caterpillars already in the leaves.
Pros
Cons
Best for: A first monitor for a pot or a short hedge when you want the largest UK review sample in this table.
Less suitable: You need a lure count that the title and the bullets agree on, or you already own a cage and only need sachets.
Specifications
Common questions
How many lures are in the box?
The title says three pheromone lures. A feature bullet says four, each active for about four to six weeks. Count the sachets when the parcel arrives.
Does a full trap clear the caterpillars?
No. Reviewers who caught moths still describe picking caterpillars by hand. A full catch leaves larvae already in the leaves.
Agralan’s funnel kit is £19.39 with four lures the listing calls enough for one season, hung from mid-March to October. It is 3.6 from 56 amazon.co.uk reviews. One buyer reports at least two moths a night after a bad caterpillar year; another saw almost nothing from mid-March until June, then six box tree moths, after four days of hand-picking. “RHS” sits in the product name. The RHS names Agralan among suppliers of monitors, which is not a score for this ASIN. The page says the plastic is recycled and made in the UK, and that the trap is completely harmless to pets, while the bucket still holds water. The change interval is not printed as a number of weeks, only as four lures for a season. It is a reasonable four-sachet kit near £19 if you treat the RHS word as a name.
Pros
Cons
Best for: A four-lure funnel near £19 when you already know the RHS word is the product name.
Less suitable: Anyone treating the title as an RHS score, or a garden that needs a printed weeks-per-lure figure before buying.
Specifications
Common questions
Does RHS in the name mean the RHS tested this trap?
No. RHS sits in the product name. The RHS names Agralan among suppliers of monitors. That is not a score for this listing.
How often is each lure changed?
The listing calls four lures enough for one season, from mid-March to October. It does not print a number of weeks per lure.
COMPO’s transparent boxwood moth trap is the dearest kit on this shelf at £29.57, with three attractant dispensers the listing says last about two months. Across 255 amazon.co.uk reviews the star line is 3.4, a large sample that still sits below the clearer four-star kits. The bullets claim the trap stops females laying eggs, which runs ahead of the 2019 RHS review: gravid females are not drawn to the lure. A seller line of up to 180 m² is printed on the page and is not a British Standard. Insecticide-free is stated, and that is not the same as a water tray being harmless to every animal that can reach it. The saved review excerpts do not name one repeated breakage, so the limit you can see is the price and the coverage wording. You pay about £10.50 more than the top-pick kit without a different biological result.
Pros
Cons
Best for: A reusable transparent monitor when you specifically want three long-stated dispensers and will ignore the 180 m² line.
Less suitable: A first hedge on a budget under £20, or anyone reading the listing as proof the trap stops egg-laying.
Specifications
Common questions
How long do the dispensers last?
The listing says the three attractant dispensers last about two months, about eight weeks.
Does the 180 m² line mean the trap covers that area?
No. Up to 180 m² is seller wording on the page. It is not a British Standard and it is not a tested radius.
SWISSINNO’s reusable trap is the cheapest kit in this set at £15.37, model 1 441 001K, about 100 g, country of origin Slovenia. The listing does not state how many pheromone capsules are in the box or how long each lasts. It scores 2.9 from only 12 reviews. One buyer with a clear infestation caught nothing, found the instructions unclear, and says the sticky clear insert was packed so that it bent back on itself. Another says it has not worked yet this season. The best-value badge sits on that price, under £17, not on the star line. The sample is too thin and too weak to call the trap well liked. It can be a first body if £15 is the ceiling and the capsule inside really is a box tree moth lure; it is the wrong pick if you want a water bucket with a large UK review count.
Pros
Cons
Best for: A cheapest-possible reusable body when you will check that the capsule is a box tree moth lure and you accept a weak, small sample.
Less suitable: Anyone choosing on stars, or a hedge where you want a large review count and a known number of sachets.
Specifications
Common questions
How many lures does the listing include?
The saved listing does not state a lure count or how long each capsule lasts. Check the capsule is a box tree moth lure before you hang it.
Why is this the best value if the stars are low?
It is the cheapest kit here at about £15.37, under £17. The star line is 2.9 from 12 reviews. The badge is the price of a reusable body, not the stars.
Twelve amazon.co.uk listings were scored from stars, review-sample size, trap fit and price. Refill-only packs stay in the table and are excluded from the badges. There is no laboratory catch trial. The top pick is the highest score among trap kits. Best value is the cheapest trap kit, under £17. Seller coverage lines are not treated as a tested radius. The scoring note uses 40, 22, 25 and 10.

Start with a trap body if you do not already own a cage. A refill is sachets only. On this saved amazon.co.uk shelf, refills are about £10.99–£12.99 and most kits about £15.37–£19.99, with two dearer kits above that. A first monitor is the usual buy under £20. A stated coverage in square metres is seller wording, not a tested radius. The top pick and the best value are both kits. A catch shows males are flying. It does not clear caterpillars.
A box tree moth trap is a reusable funnel or clear container you hang beside box, Buxus. The lure is meant to draw male Cydalima perspectalis into water, often with a drop of detergent. UK use is monitoring: you want to know if males are flying. You are not clearing caterpillars already in the leaves. The Royal Horticultural Society treats a catch as a warning and an empty week as inconclusive, because females that are ready to lay are not attracted. Trapping males does not stop egg-laying.
A sachet pack needs a lure cage you already own. Four listings here are refills. They do not monitor a hedge on their own.
The RHS treats a catch as a warning and an empty week as inconclusive. Gravid females are not attracted, and cool weather can pause catches.
180 square metres, 200 square metres, one trap per 250 square metres, and one per half an acre are seller wording, not a British Standard. One bucket on a long hedge is a sample.
The first split is body versus refill. A kit is a trap you can hang. A refill is foil sachets for a cage already on the hedge. Buying the sachets first leaves you with nothing to put them in. The second split is species. This lure is for box tree moth on Buxus. It is not a clothes-moth trap and it is not a pantry-moth trap. Indoor wording on a box-tree listing is the wrong room, and the wrong insect. The third split is whether the title and the bullets agree on the lure count.
A trap shows when males are flying. It does not remove caterpillars already feeding, and it does not stop egg-laying. The 2019 RHS review says gravid females ignore the lure, and one or two males can still mate. Hand removal on a small bush comes before a spray. Hang height and water depth belong to the leaflet in the box. Published notes differ: about 1.5–2 m and about 5 cm of water plus detergent, or 1–2 cm on another sheet.
Three typical situations, each with a recommendation from this comparison.
You will look weekly and you want one kit under £20. The IPM Direct box tree moth trap is about £18.99, with 3.7 from 290 reviews, the largest kit sample here. The title says three lures and a bullet says four, so count the sachets. It is a weaker match if you need a lure count the page agrees on, or you already own a cage.
You only need sachets. The IPM Direct lure refills are about £12.99, with 3.9 from 157 reviews, the largest refill sample here. The title says four and another line says three, so do not fix a price per lure until you count them. Skip the pack if you still need a bucket.
One bucket samples a long run. It does not cover it. The BuxTrap refillable box tree moth trap is about £16.99, with four lures stated at four to six weeks and 4.2 from 146 reviews, the stronger large-sample star line among the bodies. Reviewers call the plastic flimsy. It is the wrong parcel if you only wanted sachets.
The top pick is the IPM Direct box tree moth trap at about £18.99. It is the highest score among trap kits: 3.7 from 290 amazon.co.uk reviews, the largest kit sample, with a reusable clear casing under £20. The title says three lures and a bullet says four, so count the sachets. A full catch still leaves caterpillars in the leaves. The best value is the SWISSINNO box tree moth trap at about £15.37, the cheapest kit here. The listing does not state a lure count or a lure life, and the star line is 2.9 from 12 reviews. The badge is the price, not the stars. Refill-only packs were kept out of both badges. None of these scores is a garden trial.
