We have been having some fruit fly issues in our house lately. They are so annoying and just plain gross. The other day I came home from work to find a small bowl covered with plastic wrap on the counter by the fruit. I was pretty curious to what it was. It was my sweet nine year old and she created a fruit fly trap. She put a small piece of banana in the bowl, covered it with plastic wrap, taped it to the bowl and poked a few small holes in it. I don't know where she got the idea, but it worked brillantly. The flys go in through the holes and can't get out.
This is after just a day. Check out all the flies it caught. Our fruit fly issue was solved!
