Fruit Fly Trap

Confession:  We have a lot of bugs.    Partly because we live in the country where there are a lot of bugs.    And partly because sometimes we bring a bit of the country indoors. 

During canning and harvest season we get a lot of fruit flies.  

I've never been a big fan of fruit flies.   Partly because they're annoying.   And partly because in the 9th grade we had to raise them in biology class for a genetics experiment.  It had something to do with red eyes.   I think.   Anyway, the fruit flies often escaped and for several weeks the entire 9th grade area and the cafeteria suffered a pestilence of fruit flies.   Yuck. 

When I started making my own vinegar we got a few more fruit flies.   In the summer, when the vinegar warms up, we get more fruit flies.   When we bring in the latest garden produce and it sits on the counter for a day, we get more fruit flies.    Sometimes we suffer a pestilence of fruit flies.   


I read somewhere about making a fruit fly trap with vinegar and water and soap.    So I tried it.  

And it works.   It really, really works.   

I have two now.   I keep one by the vinegar and one on the kitchen counter where we do food prep - that's the one in the pic.     If you blow up the pic, you'll see the little drowned fruit flies in the bottom of the jar.    My name is Robin E. and I'm a fly murderer.  

This is what you need to make your own fly execution chamber - just in time for Halloween:
  • 8 oz jar  [Can be bigger or smaller.  This is America.  Use whatever jar you want.]
  • 1/2 cup of water
  • 2-3 Tablespoons cider vinegar 
  • A few drops of dish soap
The vinegar draws the flies in.   The soap breaks the surface tension of the water, so when the flies touch the water to investigate, they fall in.   Genius.

It'll stay effective for a long time.   It doesn't smell unless you put in a lot of cider vinegar and you're sensitive to the vinegar smell.  


  1. I am definitely going to try this because this year it got so bad we even bought fruit fly traps from Gardener's Supply but those didn't work either. Grrrr. Thanks for the "recipe"!

    1. Actually I hate Fruit Fly.Yes ! It's works and You can try this Traps.thanks

  2. I HATE FRUIT FLIES! I get them every year too. My trap consists of about an inch of red wine (or vinegar) in a jar or glass, covered with clear plastic wrap. I poked about 6 holes in the top with a toothpick. They fight to get in, but they never get out. I too am a murderer.

  3. Brilliant!!! I will definitely give this one a go. I am happy to be a murderer of fruit flies. Good way to get out the aggressions? LOL...

  4. we have those critters in the motorhome right now. I'm going to make my execution chamber right now!

  5. You're a boss. I just made one of these and in less than an hour two of the little buggers have already plunged to the briny depths.

  6. Thanks for your sharing here! I am definitely going to try this
