How to Select the Right Mason Jar to Trap Fruit Flies

When it comes to the mason jar you select for your fruit fly trap, there are various options because mason jar come in LOTS variations.  We recommend a regular mouth pint jar or even the 12 ounce jelly jars.  Select one that matches your kitchen décor if you like, as the jar will be sitting out near your fruit bowl.

The pint jar is the optimal size because it provides sufficient space for the bait and is not too large to have hanging out on your counter.  A quart jar leaves much more space between the top of the jar and the bait which may decrease the flies’ ability to find it and become trapped.


What kind of Bait Should I use to Trap Fruit Flies?

Lots of different things work for baiting fruit flies.  We find that the most effective bait to attract fruit flies is apple cider vinegar.  However, you can read about how to trap fruit flies without vinegar in this blog post: How To Trap Fruit Flies Without Vinegar.

Fruit flies can’t seem to resist apple cider vinegar.  Even as small amount as 1/4 cup is sufficient to lure the pests to their demise.  We recommend 1/4 to 1/2 cup in the bottom of a mason jar.


The Culinesco® Fruit Fly Funnel is designed to insert into the regular mouth mason jar, but should be secured with a regular metal band.  It’s dishwasher safe and easy to use.

Simply add apple cider vinegar to the jar, insert the Fruit Fly Funnel and secure with a band.  Lastly, place the jar next to your fruit and watch your fruit flies disappear.
