The best fruit fly traps, compared.
Top pick: LFSYS yellow sticky traps, 96 pack – Highest score in this comparison, 9.4 out of 10, from 1,907 amazon.co.uk reviews. Best value: Super Ninja fruit fly trap, 2 pack – Smallest Super Ninja pack here at about £9.99, with 3.8 from 25,181 reviews, the gnat exclusion, and GB-2026-1354 printed. Updated October 2026.
A fruit fly trap on amazon.co.uk is usually a small bottle of fermenting-fruit lure, a yellow glue card, or a plug-in UV light with a hidden sticky pad. In a UK kitchen the insect you mean is the vinegar fly, often melanogaster, drawn to overripe fruit, recycling dregs, and the food-waste caddy. Flies on damp compost are usually fungus gnats. Flies at the plughole are often drain flies. A fruit fly trap is judged by insect and mechanism, placement and the source, and authorisation and the plug. How to choose is set out in the [fruit fly trap buying guide](/hub/traps/fruit-fly-trap/sub/fruit-fly-trap-buying-guide).

Personal buying guide
Question 1 of 2
Where are the flies?
Ninety-six double-sided LFSYS yellow cards and a small soil shovel cost about £13.99. The large pack gives houseplant owners many placements without a plug, spray, or scented lure. Stored reviews describe catches around damp compost, and also glue on fingers and leaves. One stored review says the cards do not catch fruit flies. The 4.7-star line is based on 1,907 ratings. The written texts in this file come from Germany and the United States. These cards suit indoor fungus-gnat monitoring if you accept that evidence gap. They are the wrong tool for a kitchen vinegar-fly problem, and the outdoor permission in the bullets sits against non-target warnings.
Pros
Cons
Best for: Indoor pots when you want a large card count and you accept the review-country gap.
Less suitable: A reader who needs UK review texts, or a kitchen vinegar-fly job.
Specifications
Common questions
What insects does the listing name?
The title and bullets name fruit flies, gnats, whiteflies, aphids, and leaf miners.
Are the written reviews from the UK?
The 50 review texts in this file are from Germany and the United States. The star line on the file is 4.7 from 1,907.
What if the glue is soft?
The bullets say hot weather can melt the glue and make the white paper hard to tear, and they suggest refrigerating the pack for half an hour.
Sixty double-sided Blooven yellow cards provide many soil-level placements for about £6.99. UK reviewers praise their stickiness, lack of odour, and catches around orchids and other houseplants. Those reports concern fungus gnats. The 4.3-star line comes from 24,917 reviews and belongs with that plant-trap context, not with a kitchen vinegar-fly test. Cards catch adults, and they work alongside drier compost. The bullets say to keep them indoors. They suit indoor pots. They are the wrong tool for a fruit-bowl infestation.
Pros
Cons
Best for: Fungus gnats in indoor pots, alongside drier compost.
Less suitable: A fruit-bowl infestation, or outdoor plants where bees can reach the glue.
Specifications
Common questions
Can they go outside?
The bullets say do not use them outdoors, to protect bees and also snakes, lizards, and birds.
Where do they sit?
Peel off the white paper and slide the card into the potting soil.
Do they smell?
The bullets say odourless and tasteless.
Two Entopest traps combine 40 ml of vinegar-based lure with a yellow adhesive insert for about £12.99. The fold-out design hides much of the catch, and favourable UK reviews call it tidier than exposed fly paper. Some users report catches near a food-waste bin and describe a mild smell. Others mention a strong vinegar or glue odour, and one reviewer caught a single fly during a week of heavy activity. The 3.9-star line comes from 39 reviews. No week count and no authorisation number appear in the file. A non-toxic line on the listing is a bullet, and this page does not treat it as a certificate.
Pros
Cons
Best for: A kitchen where an open fly paper would be in the way.
Less suitable: A plant-gnat problem, or a buyer who wants a numbered biocide authorisation on the listing.
Specifications
Common questions
How do you set it up?
The bullets say peel, fold into a triangle, and place it next to a breeding site.
Is the catch visible?
The bullets say a decorative closed design keeps trapped insects out of sight, and that flies are captured on a yellow adhesive insert.
Does it smell?
The lure is described as vinegar-based. Reviews mention both a mild smell and a strong smell.
Six Super Ninja bottles give a longer sequence of pre-baited traps for about £21.99. The listing claims up to three weeks per bottle and prints authorisation GB-2026-1354. UK reviewers often praise quick catches and the discreet bottle. Strong vinegar smell, slow starts, and flies leaving the rim recur as criticisms. The 3.8-star line is based on 25,268 reviews, and those review texts overlap the 12-pack file, so they are not an independent sample for this pack. It suits repeated indoor vinegar-fly use. A one-week problem does not need six bottles, and the listing excludes gnats.
Pros
Cons
Best for: A kitchen that will open a fresh bottle every few weeks.
Less suitable: A one-week problem, or a reader treating the 25,268 reviews as unique to this pack.
Specifications
Common questions
Can you reuse the bottles?
The page asks if it is reusable. The bullets describe a pre-filled bottle and do not say you refill it.
Will it catch gnats?
The listing says it is for fruit flies and will not work for gnats.
Are the reviews only for this 6-pack?
The file shows 3.8 from 25,268 reviews, and the opening review texts match the 12-pack file.
Twelve Super Ninja bottles are the lowest shelf price per bottle among this brand’s packs here, at about £37.99, and that saving applies only if you will use them. Each bottle is claimed to last up to three weeks, and the listing prints GB-2026-1354. Review themes include fast catches and a discreet size, and also vinegar smell, slow starts, and flies sometimes walking back out. The 3.8-star line from 25,268 reviews is shared with the six-pack file. An electric attribute conflicts with bullets that describe a liquid bottle. This bulk pack suits a long indoor vinegar-fly problem. It is a poor fit for a short trial, a plug-in buyer, or fungus gnats.
Pros
Cons
Best for: Someone who will use many bottles over a long indoor problem.
Less suitable: A buyer who wants a plug-in unit, or who only needs one week of trapping.
Specifications
Common questions
Is this pack electric?
The attribute line says electric. The bullets describe the same liquid bait bottle as the smaller packs and do not mention a plug.
How many traps are in the box?
The included-components line says 12 fruit fly traps.
Do the reviews differ from the 6-pack?
This file also shows 3.8 from 25,268, and the opening reviews match the 6-pack file.
Two Super Ninja bottles at about £9.99 are the best value when one kitchen needs a pair and a larger pack would sit unopened. The UK listing prints authorisation GB-2026-1354, claims up to three weeks each, and says the trap will not work for gnats. The review line is 3.8 out of 5 from 25,181 reviews. The written texts overlap other Super Ninja pack files, so treat that volume as a shared brand line. The attribute field says AC, and the bullets describe a liquid bottle with no plug.
Pros
Cons
Best for: A kitchen vinegar-fly outbreak if you want two pre-baited bottles and you will read the label.
Less suitable: Fungus gnats in houseplant compost, or anyone who needs a stated BS 1363 plug.
Specifications
Common questions
Will it catch fungus gnats?
The listing says this trap is for fruit flies and will not work for gnats.
How long does a bottle last?
The listing claims up to 3 weeks of coverage per bottle.
Does it plug in?
The bullets describe a liquid bait bottle. The attribute line says AC, and no plug is described.
Four Super Ninja bottles provide several indoor placements or replacement cycles for about £15.99. The 3.8-star line comes from 19,611 reviews, and that count differs from the other pack sizes in this set. Reviewers repeatedly report catches within a day or two, while others mention a slow start or flies walking back out. The vinegar smell on opening is another recurring drawback. The printed GB-2026-1354 authorisation and the explicit gnat exclusion are the reasons this pack is the top pick for a confirmed kitchen vinegar-fly problem. It is the wrong tool for fungus gnats or outdoor trapping.
Pros
Cons
Best for: Several indoor spots in one kitchen, if the flies are vinegar flies.
Less suitable: Compost gnats, or outdoor use.
Specifications
Common questions
Is it for the garden?
The page asks about garden use. The bullets describe an indoor trap for counters, bins, and fruit.
Is it safe around food?
The page asks, and the bullets say it is safe around children and pets. The same listing says to read the label and product information.
Will it catch gnats?
The listing says it is for fruit flies and will not work for gnats.
Two Trappify hanging sticky tubes are about £12.99 and claim up to 90 days. UK reviewers report catches across several insect types, and some prefer the format to sprays. The exposed adhesive is repeatedly described as extremely sticky, difficult to position, and liable to catch indiscriminately. No fruit-fly bait is in the box. The bullets suggest a dab of honey, and reviews also mention cider vinegar. The 3.6-star line comes from 6,255 reviews. It suits a carefully chosen hanging position where exposed glue is acceptable. It is a poor match for a discreet, pre-baited kitchen bottle.
Pros
Cons
Best for: House flies or a covered outdoor spot, if you accept exposed glue.
Less suitable: A discreet kitchen bottle for vinegar flies only.
Specifications
Common questions
Does it come with bait?
The bullets say no sprays, plugs, or batteries. They say a dab of honey turns the tube into a fruit-fly trap.
Can it be reused?
The style name is Disposable. The page asks about reuse and the bullets do not describe a refill.
What should it stay away from?
The bullets say handle it by the cap and keep it away from hair and curtains.
Two ready-to-use GroundMaster bottles provide 20 ml of lure each for about £9.99. The listing prints apple juice 43.6%, grape juice 23.6%, water 30.3%, white sugar 2.2%, and coco amides 0.3%, and it claims up to three weeks per bottle. One reviewer says the trap worked for that stated period and smelled of fruit juice. The 3.5-star line rests on two UK reviews, one of them a Vine review, so no reliable defect pattern can be drawn. Refill use and an authorisation number are absent from the file. This pair suits a short indoor trial when you want the recipe in writing.
Pros
Cons
Best for: A short indoor trial when you want the bait recipe in writing.
Less suitable: A decision that needs a large UK review sample.
Specifications
Common questions
How long does one bottle last?
The bullets say each 20 ml bottle stays effective for up to 3 weeks, and that using one at a time gives up to 6 weeks from the pair.
Can you refill them?
The page asks. The bullets do not say the bottles are refilled.
What is in the bait?
The listing prints apple juice 43.6%, grape juice 23.6%, water 30.3%, white sugar 2.2%, and coco amides 0.3%.
The Homealexa plug-in is about £13.99, measures 15.5 x 10.5 x 8.5 cm, and includes six adhesive cards. The UK review line is 2.6 from 87. The texts split between no catch and a slow count on the pad. Reviewers who dislike a vinegar smell note that this unit has none. Refills after the six cards are hard to find in those reviews, and moths and bluebottles are named as misses. Voltage and BS 1363 are absent from the file. The attribute line says ac_dc, and the bullets also name garages and chicken coops. It suits a kitchen socket when you want light instead of a vinegar smell and you have read the mixed reviews.
Pros
Cons
Best for: A kitchen socket when you want light instead of a vinegar smell, and you have read the mixed reviews.
Less suitable: Bluebottles, or a buyer who needs a stated UK plug standard.
Specifications
Common questions
Can it go in a bedroom?
The page asks, and the bullets include bedrooms, with a cover to reduce glare and three brightness levels.
Does it use chemicals?
The bullets say it works without sprays, chemicals, or odours.
What is the plug standard?
The listing says a 180 degree rotating plug. Voltage and BS 1363 are not stated.
Nine ENTOEND bottles provide 15 ml pre-baited traps for about £19.99, with Drosophila melanogaster named as the target. The pack offers several indoor placements and claims an anti-spill bottle. The 2.5-star line from 43 reviews is the weakest among the liquid bottles here. Many of the 31 UK texts report no catch, or flies landing and leaving. A smaller group found the discreet bottle caught some flies near fruit. A vinegar scent is also mentioned. The title’s “up to 6 months” line is a pack claim beside a per-trap figure of up to three weeks. It suits a buyer who wants several small indoor bottles and has read the low review line.
Pros
Cons
Best for: A buyer who wants several small indoor bottles and has read the low review line.
Less suitable: Someone choosing mainly on star rating.
Specifications
Common questions
Which fly is named?
The attribute line says fruit flies, Drosophila melanogaster.
Does it claim to be spill-resistant?
The bullets describe an anti-spill bottle. They do not show a test.
Is it for pets?
The page asks, and the attribute line includes Pet-Safe. That is a listing phrase, not a separate certificate in the file.
The URBZUE plug-in combines UVA and blue LED light with a covered glue board and six refill pads for about £13.99. Quiet operation and concealed adhesive appeal to reviewers who dislike zappers, and a minority report fewer insects in the kitchen. The dominant UK review theme is zero catch after several days, reflected in a 2.1-star line from 352 reviews. Buyers also question where to obtain replacement pads after the six supplied. The body can obstruct a crowded socket. Voltage and BS 1363 are absent from the file. Two reviewers mention about £19.99 while the stored shelf price is about £13.99. It is a weak bet where a fermentation smell is the known lure.
Pros
Cons
Best for: A socket where you want a covered glue board and you accept a weak fruit-fly review line.
Less suitable: A vinegar-fly job where smell is the known lure, or a socket with no clearance.
Specifications
Common questions
Does it use insecticide?
The bullets say it works without insecticides, sprays, or chemicals, and that insects stick to a hidden board.
Will it catch fruit flies?
The listing says it attracts fruit flies. Many UK reviews in the file report no catch. That is a review theme, not a lab result.
What plug is it?
The listing says a 180 degree rotating plug. It does not state BS 1363 or a voltage.
Shelf prices, stars, and review counts are the amazon.co.uk figures stored for these twelve listings, captured on 15 October 2026. They are not a live reload on 17 October 2026. Each card score is the 0–100 figure already stored for this set, a star conversion, with listing conflicts kept in the text. It is not a laboratory catch test. Pre-baited lures are treated as a label-and-authorisation question. Use biocides safely. Always read the label and product information before use.
Insect and mechanism
30%Vinegar flies sit on fruit, wine, and bins, and the matching trap is a smell lure. Fungus gnats run on compost, and the matching trap is a yellow card at soil level. A high star line on the other job stays with that job.
Placement and the source
20%The trap needs to sit within about a metre of the breeding source. Rotting fruit, empties, and an open food-waste caddy stay in the decision, because a trap alone leaves that source in the room.
Life, pack, and price
20%Several liquid listings claim up to three weeks a bottle. A larger pack is cheaper per bottle only if you will open them. Prices here are this set’s shelf figures, from about £6.99 to about £37.99.
Authorisation and the plug
15%A baited lure can be a biocidal product. Super Ninja prints GB-2026-1354 on these listings. Plug-ins in this set do not state BS 1363 or 230 V, so that line stays open.
Listing evidence
15%Stars and review counts come from the amazon.co.uk line in each file. Points stay with the text where an attribute fights the bullets, or where two Super Ninja packs share the same review dump.
Name the fly, then the mechanism, then the spot within about a metre of the source. A star rating on a yellow card does not answer a vinegar-fly question. The twelve listings below are amazon.co.uk pages captured on 15 October 2026, with the prices and review counts stored for this comparison. A plug-in can look tidy. In these UK reviews it is also where a zero catch shows up.
A fruit fly trap, as UK shoppers search for it, is usually one of three things: a small bottle of fermenting-fruit lure, a yellow glue card, or a plug-in UV light with a hidden sticky pad. In a UK kitchen the insect you mean is the vinegar fly, often Drosophila melanogaster, drawn to overripe fruit, recycling dregs, and the food-waste caddy. Flies on damp houseplant compost are usually fungus gnats. Flies at the plughole are often drain flies.
Super Ninja’s listing says the bottle will not work for gnats. Fungus gnats run on damp compost. The matching trap in this set is a yellow card slid into the pot, used with drier compost. A vinegar smell next to a fruit bowl does not answer a sciarid problem.
Which? and BPCA both treat a trap as incomplete while rotting food, empties, and spills stay. Pest Evidence, citing BPCA identification guidance, puts fermentation attraction at about a metre. An open food-waste caddy across the kitchen keeps feeding the flies the bottle is meant to draw.
URBZUE is 2.1 from 352 reviews and Homealexa is 2.6 from 87. Many UK reviews in those files report no catch. Vinegar flies follow a smell. Neither plug-in states BS 1363 or 230 V. A covered glue board can still be the wrong mechanism for this insect.
Vinegar flies sit on fruit, wine, and bins. Fungus gnats run on compost. Drain flies sit on sinks. Super Ninja’s own bullet says the bottle will not work for gnats. A smell lure matches vinegar flies. A yellow card at soil level matches fungus gnats. Hanging glue is a general fly surface, and Trappify ships without a fruit-fly bait in the box.
Several liquid listings claim up to three weeks a bottle. Super Ninja shelf prices on these files are about £9.99 (2), about £15.99 (4), about £21.99 (6), and about £37.99 (12). A bigger pack is cheaper per bottle only if you will use them. The 4 pack is the top pick because the listing names fruit fly, prints GB-2026-1354, and its 19,611 reviews are a different count from the shared 6-pack and 12-pack dump. The 2 pack is the best value at about £9.99 when two bottles are enough.
Three typical situations, each with a recommendation from this comparison.
Flies are on the fruit bowl, the wine glass, or the food-waste caddy, and you want more than one indoor bottle. The Super Ninja 4 pack is about £15.99, names fruit fly, and prints GB-2026-1354. The listing says the bottle will not work for gnats.
The flies run on damp compost, which is a different insect from a vinegar fly. Blooven’s 60 yellow cards are about £6.99 and the bullets say to slide them into potting soil indoors. The UK review texts in that file are about plant gnats.
You want the same Super Ninja liquid bottle and you will use two, not a cupboard of twelve. The 2 pack is about £9.99, with 3.8 from 25,181 reviews. The attribute line says AC while the bullets describe a bottle, so that conflict stays in the score.
The top pick is LFSYS yellow sticky traps, 96 pack, with the highest score in this comparison (9.4 out of 10, from 1,907 amazon.co.uk reviews). The best value is the Super Ninja 2 pack, at about £9.99, when two bottles are enough, with 3.8 from 25,181 reviews and the same gnat exclusion. Yellow-card stars belong with indoor pots. Plug-in UV in this set sits on 2.1 from 352 and 2.6 from 87, and many of those UK reviews report no catch. Clear the fruit, the empties, and the caddy, and site the trap within about a metre of what is left.
