Tiny flies round the fruit bowl, the bin, or your houseplants, and not sure which trap to buy?
Work out which fly you have first. Fruit flies hang around fruit, bins, and the sink, so a liquid bait fruit fly trap is the usual pick. Fungus gnats hover over houseplant compost, so yellow sticky cards in the pot are the usual pick. One type rarely does both jobs well.
Last updated: 8 October 2026
Indoor fruit fly traps and yellow sticky traps are near the top of the Amazon UK Garden bestseller chart this week. This is a practical UK shopping shortlist for fruit fly and fungus gnat traps on amazon.co.uk. It is not pest control advice for a serious infestation, and it does not invent prices, catch rates, or stock dates.
Fruit flies or fungus gnats: how to tell
Fruit flies are small, tan or brown flies, often with red eyes, that gather near ripe fruit, open bins, recycling, drains, and spilled drinks. Fungus gnats are darker, slimmer, and longer legged, and they rise from the compost when you water or brush past a houseplant. If the flies cluster at the fruit bowl, think fruit fly. If they cluster at the plant pots, think fungus gnat.
Best pick for fruit flies in the kitchen
Liquid bait traps sit on the worktop or near the bin and lure fruit flies in. The charting Super Ninja listing says its trap is for fruit flies and will not work for gnats, which is exactly why the type of fly matters before you buy.
- Super Ninja fruit fly traps for indoors (2 pack) for one kitchen and one bin or utility area
- Super Ninja fruit fly traps for indoors (4 pack) if you want spares or traps in several rooms
- fruit fly trap search on amazon.co.uk to compare other bait traps
The listing gives a use period per bottle, so check the current wording on the day you buy and plan replacements around it.
Best pick for fungus gnats in houseplants
Yellow sticky cards are a simple physical trap: flying insects are drawn to the colour and stick to the card. Push the stake into the compost or hang the card just above the leaves. Double sided cards catch from both faces, and a big pack lets you swap cards out as they fill up.
- Blooven double sided yellow sticky traps (60 pieces) for several houseplants and regular swaps
- yellow sticky fruit fly and fungus gnat traps (12 pack) for a smaller set in decorative shapes
- yellow sticky traps search on amazon.co.uk to compare pack sizes
Read the listing notes on where to use them. The Blooven listing says its cards are for indoor use, not outdoors, to protect bees and other wildlife, and the 12 pack listing says to keep children and pets away from the cards.
Do traps fix the problem on their own
Traps catch adults, so they work best alongside removing whatever the flies are breeding in. For fruit flies, that means ripe fruit kept in the fridge or eaten, bins and recycling rinsed and emptied, and sink drains kept clean. For fungus gnats, many houseplant owners let the top layer of compost dry out between waterings, because the larvae live in damp compost. If the flies keep coming back in large numbers, the source is probably still there.
