A fruit fly trap catches the adult fruit flies with a lure that smells of fermenting fruit. Put it next to the fruit bowl or the bin and clear the source at the same time. In independent testing the Super Ninja Fruit Fly Trap caught 84.9% of fruit flies within 24 hours, and one trap works for up to 3 weeks.
Choose the Super Ninja Fruit Fly Trap, 2 pack for an ordinary kitchen, the Super Ninja Fruit Fly Trap in 4, 6 or 12 traps for more rooms, or the Super Ninja Fruit Fly Trap & Fungus Gnat Killer Combo if you are not sure which fly you have.
How does the Super Ninja Fruit Fly Trap work?
With smell. Each trap holds 18 ml of lure made of 37.5% vinegar and 5% apple juice concentrate. It smells of fermenting fruit, and that is what fruit flies go for. Once inside the bottle, they cannot get back out. The 4, 6 and 12 packs stick discreetly out of sight with the stick and go strip. Up close you will smell vinegar; that is exactly what draws the flies in.
How quickly does a fruit fly trap work?
The first flies are usually in it within a day. In an independent test by the SAGEA laboratory (report 4540.SAG, September 2021) our trap caught 84.9% of fruit flies within 24 hours. Fruit fly food was deliberately placed in the same room, a metre away, so the flies had a real choice. The traps filled with water alone caught no flies at all. With a large infestation it takes longer, because eggs are still hatching: allow a week or two.
How many fruit fly traps do you need?
Allow one trap per 30 cubic metres, which is a kitchen of about 12 square metres. In an ordinary kitchen you put out two: one by the fruit bowl and one by the bin. If you have a larger kitchen or flies in more places, choose 4, 6 or 12 traps.
Where should you put a fruit fly trap?
Within a metre of the source and on a flat surface: next to the fruit bowl, by the bin or the food waste caddy, or by the sink. Not on the windowsill and not in the middle of the dining table. Fruit flies follow smell, not light, so a trap far from the fruit catches little.
Do you need to shake a fruit fly trap?
Yes. Give the bottle a quick shake and unscrew the cap, then follow the steps on the pack: with the 4, 6 and 12 packs you peel off the sticker and fix the trap in place, with the 2 pack you wipe the yellow funnel dry. Do not top it up and do not rinse it.
How long does a fruit fly trap last?
Up to 3 weeks per trap. Once the bottle is full or the 3 weeks are up, replace it with a new one.
What should you look for when choosing a fruit fly trap?
- Has it been tested? Ask for a percentage and a report, tested in a room where other food was present too.
- Does it lure with smell? Fruit flies follow smell, not light or colour.
- How long does it work without upkeep? A homemade trap needs refreshing every few days.
- Can you place it close to the source? A trap you can put right next to the fruit bowl catches more than one on the windowsill.
- Does it have an authorisation number? The lure in the Super Ninja Fruit Fly Trap is an authorised biocide, number GB-2026-1354-002.

Does an electric insect lamp work on fruit flies?
Barely. That kind of lamp attracts with blue and UV light, and fruit flies hardly respond to it. They follow scent, specifically fermenting sugars. So place a trap at the source, not by the window or under a lamp.
Are they fruit flies or fungus gnats?
Look at where they are. Around the fruit or the bin they are fruit flies, and that is what this trap is for. If they come out of the compost of your houseplants, they are fungus gnats; you catch those with yellow sticky traps for fungus gnats. A drain can hold fruit flies as well as drain flies; the tape test shows which (see small black flies in the house). Read more about the difference in fruit flies or fungus gnats?
