We have been overrun by fruit flies. It’s gross and embarrassing.
So, we’re fighting back.
This is simply a jar. With vinegar in it. And a drop of dish soap to kill the surface tension.
Yes, it’s THAT easy. (However, I did notice that a lot of them are using the rim as a hang out, so I’ve now covered it wtih plastic wrap with holes poked in the top in the hopes that I will trap them that way as well.)
Die fruit flies, die!
