A fruit fly trap from the bottle on the counter.

A one-way entry cone screws onto a bottle of bait. Flies and gnats go in, they don’t come out. Empty the bottle, refill the bait, reuse the cap.

Two CapTool Trap caps in translucent amber with mint green accent, one screwed onto a clear bottle on a kitchen counter holding apple cider vinegar bait, with fruit flies entering through the cone

How it works

Pour bait. Snap on. Wait.

1

Pour the bait

Apple cider vinegar with a drop of dish soap is the classic. Other recipes on the included card.

2

Snap on the trap cap

The cone shape lets flies in but makes finding the way out close to impossible.

3

Set it on the counter

Near the fruit bowl, the compost bin, or the sink. Empty and refill when full.

Targets fruit flies and gnats. Not mosquitoes.

Trap is built for the bugs that show up around fruit, compost, drains, and houseplants. The bait works on common house gnats and fruit flies. With sweet bait it also draws yellow jackets at picnics and outdoor events.

Mosquitoes are not in the use case. They’re drawn to body heat and exhaled CO2, not bait, and Trap won’t do anything for a mosquito problem.
