Equipment for a Gnat Trap Recipe

If you are like me, you enjoy keeping a few produce items un-refrigerated; tomatoes especially are so much more flavorful, juicy and did I say flavorful when they hang out on the counter.

But do you find yourself seeing itsy-bitsy black insects flying around, flies and gnats dive bombing your face? You end up looking like one of those clapping monkey’s as you try to smack the darn things; looking like a fool? Just me?

How to Get Rid of Fruit Flies with Vinegar

This fruit fly trap is so simple, I am sure you have the ingredients at home. So how do you make a fruit fly trap with vinegar?

Simply pour apple cider vinegar or white vinegar into a ramekin, leaving about 1/2 inch at the top.

Cover snugly with plastic wrap, pull tight, sealing tightly and taught, all the way around the ramekin.

Using a toothpick or an ice pick, puncture holes in the top of the plastic wrap, swirling slightly to enlarge the hole a bit larger than the toothpick makes by itself.

Pro Gnat Trap Recipe Tip

If the fruit flies (or gnats) are attracted to the trap, but not going in (walking all over the top of the plastic wrap), it typically means your holes aren’t big enough.

Without making the holes too big, use a toothpick to slighly swirl and enlarge your holes, remember you don’t want them flying back out, warning their fly friends. Make it easy for them to get in and never get out. 🙂

After a few days the vinegar loses it’s drawing power, toss out, wash the bowl and start over again. You’ll be surprised at how many you catch!

Our infestors visitors are not too prolific at the moment, but typically I’ve got 2-3 traps going and they each catch 15-20 flies a day! EW!

How to Get Rid of Fruit Flies Without Apple Cider Vinegar

I personally like using Apple Cider Vinegar for my gnat traps, however; regular white vinegar will work too!

Still want to try it? You should know quickly if it works and if it doesn’t then move on to apple cider vinegar, balsamic, red wine, anything that is naturally a bit sweeter.

  • Pour vinegar into small shallow bowl or ramekin, leaving about 1/2 inch space at top.
  • Stretch a piece of plastic wrap tightly across the top, making sure there are no gaps.
  • Insert toothpick (or icepick) through plastic wrap and swirl slightly to enlarge the hole abit.
  • Set on counter and watch the fruit flies gather for a pool party.


The vinegar loses its efficacy after a few days. Simple wash out the container, and repeat the above steps.
If the flies are attracted to your trap, but aren't going it, chances are your holes are too small (or too large), increase the size of the holes. Or if too large, replace the plastic wrap and try again. Happy catching!
