In a mason jar or glass fill the bottom with apple cider vinegar and a small piece of fruit (banana and peaches work great). Roll up a piece of paper into a cone shape with a small opening at the bottom and place in jar. Place near the swarming, aggravating, annoying, troublesome fruit flies and watch them fly down into their fateful demise. Can you sense how much they "bug" me?
You can tape the paper in place so that interested kids don't let them free! Place the jar in the freezer to ensure that they are truly captured and executed.
Then...with much joy, feel free to bring in as many fruits and vegetables as you would like! Canning tomatoes just got much more pleasant!
