Fruit flies, gnats, and ants. Caught in a bottle you already have.

Pour a little bait into a common plastic bottle. Snap on the Trap cap. The shaped one-way cone lets the insects in and keeps them in.

How it works

Pour. Snap. Wait.

1

Pour bait into a bottle

Apple cider vinegar with a drop of dish soap works for fruit flies and gnats. Use any common 28mm beverage bottle.

2

Snap on the Trap cap

The cap holds a shaped silicone cone. Insects follow the smell down through the opening and can’t find their way out.

3

Set it where the problem is

Counter, fruit bowl, sink ledge, RV galley, restaurant prep area. The bottle does the work overnight.

The cap

A one-way cone, not a sticky strip.

Detail

The cap

Food-contact silicone, BPA-free, refillable.

Kitchen, RV, restaurant prep line

The bottle sits where the problem is. The problem ends up in the bottle.

Fruit flies show up around ripe fruit, drains, and recycling. Gnats come in with grocery store herbs and houseplant soil. The Trap cap takes a bottle you already have and turns it into a refillable trap that runs while you sleep.

Refillable. No sticky strips. No aerosol. No pesticide spray near food. When the bottle is full, dump it, rinse the cap, refill the bait.

What the Trap is for

Three jobs. One cap.

1

Fruit flies

Kitchens, fruit bowls, drains, recycling bins, compost areas. Apple cider vinegar with a drop of dish soap is the standard bait.

2

Gnats

Houseplants, herb pots, greenhouses, indoor garden setups. Same vinegar bait works.

3

Ants (with ant-specific bait)

Pantry trails, garages, porches. Use a sugar-and-borax bait per the bait maker’s instructions.

Mosquitoes are not in scope for this product. Mosquito traps require a different mechanism and we do not make that claim.

Compatibility

Fits many common 28mm beverage bottles.

Most 16.9 oz waters, 1 liter waters, and 2 liter soda bottles. A clear bottle makes the demo more obvious, but any 28mm bottle works.
