Vinegar flies
Best fruit fly traps
The best fruit fly trap catches adults while you throw out the peach and rinse the bin. Fruit fly larvae are in fermenting film, not in the air. A trap with no cleanout is a hobby. If the flies are coming from the sink and ignore the fruit, you may have drain flies. That is a brush, not this trap. Use the small-fly comparison if you are unsure.

Which one to buy
Hardware
TERRO fruit-fly trap
Best counter trap — Set it beside the bowl, not in a closed cabinet. Replace it when it fills. Empty the bowl the same day or you are competing with yourself.
Hardware
Indoor fruit-fly traps
Best simple indoor trap — Any indoor fruit-fly trap in the catalog does the same job: adults in, larvae untouched. Find the potato that went liquid, the can return, or the mop bucket.
Hardware
Drain-cleaning brush
Best if the trap stays empty — If a fruit-fly trap catches nothing and you still have moth-like flies at the sink, stop buying vinegar traps. Brush the biofilm.
Sources a trap never reaches
- Recycling with a rinse of beer left in the bottle.
- A mop bucket or a floor drain in a bar.
- Onions, potatoes, and a forgotten lunch bag.
- The overflow channel of a sink, which is a drain-fly site more than a fruit-fly site.
Common questions
What is the best bait in a fruit fly trap?
A fermenting lure, which is what the commercial traps already use. Apple cider vinegar in a jar works as a homemade monitor. It still does not replace throwing out the breeding fruit.
Why did the trap fill up and the flies stay?
You caught adults and left the larvae. Find the wet organic film and remove it.
Will a fruit fly trap catch drain flies?
Poorly. Drain flies breed in biofilm and respond to a brush and an enzyme gel, not a vinegar jar on the counter.
