Fruit Fly’s are particularly attracted to again fruit as it begins to spoil. Keen sense of smell, they detect and follow the scent of the gases emit the process. For this reason, baits that work particularly well are:

  • Tropical Fruits (notably Bananas)
  • Wine
  • Apple Cider Vinegar


Be sure to clean any potential open food source before you set up a trap in a kitchen, dispose of any food going bad, and ensure your wast areas and drains are clean. In a restaurant or bar cleaning the areas around taps, bar mats or even drainage lines may be necessary. Any damp areas should also be removed.


Fruit Fly’s can potentially be well fed and not interested in finding a food source. If the trap does not work immediately, be patient. Keep at it.

Frequently Asked Questions

A: That traps are essentially little funnels with a small diameter hole just big enough to let the fruit fly in. The fruit fly’s will follow a scent trail (your bait) into the trap. Once they enter the trap they cannot escape, since there isn’t a scent trail to lead them out.
A: The trap was designed to work with most small mouth containers, which include everything from wine bottles, beer bottles, and certain plastic water/soda bottles.
A: We are dedicated to keeping trash out of the landfills and toxins off of our counters. Other traps on the market require you to throw them away in the trash after they expire and can have environmentally harsh contents. The Fly-On-In trap utilizes containers that you have on hand, already headed to be recycled. After you are done with the trap, you can toss the used bottle in the recycle and wash the trap.
A: Fruit flies are most attracted to the yeast that grows on the fruit, so some fruit works better than others. We think the best bait to use is banana (the fruit not the peel). However, people have had success with keeping a little beer or wine in the bottle. Also suggested would be adding a little instant baker’s yeast into the mix to kick the bait up a notch.All of these natural baits work better as they ripen and the yeast grows. A green banana will only get more attractive to fruit flies as it ripens. If you have the time and patience, we encourage you to experiment with different concoctions and let us know what works for you.
A: We don’t suggest using sugar, simple syrup or any syrup. If you don’t have time to experiment with different baits, start with the recommended baits (banana, wine, beer, yeast). All fruits are not created equal, so we stick with what we know works, like banana. Grapes, melon, strawberries might seem like attractive fruits, but we have found it catches far fewer fruit flies in comparison to banana. We have not had any luck with any kind of meat or pet food either.
A: Great question. There is no fruit fly trap that will capture fruit flies immediately. Fruit flies can be male, female, young, old, hungry or well fed. All of these factors contribute to the success of any fruit fly trap. We suggest waiting 24 hours (or overnight) before you should expect to catch any fruit flies. If you don’t have success after 24 hours, check to see if you have any competing food sources or if you actually have a fruit fly problem, is it gnats or drain flies?
A: A common mistake in many homes is identifying drain flies as fruit flies. Drain flies look very similar to fruit flies, but they breed/mulitply in plumbing drains and feed off the fungus that grows inside. You will most likely seem them in bathrooms and shower areas. It can be difficult to kill them, since fruit does not attract them.
A: The first step in catching any fruit flies is to eliminate any competing food sources. Competing food sources both inside and outside your home can render any fruit fly trap useless.
A: No, this trap is only for Fruit Flies.
A: No, this trap is only for Fruit Flies.
A: This trap was designed for indoor use, it is possible for it to work outside, but just like using the trap indoors, you would need to eliminate all the outdoor competing food sources, which can pose a challenge in some scenarios.
