I found this easy homemade trap over at Passionate Homemaking and tried it out this weekend. My husband was just staring at it for the longest time trying to figure out what I’m up to now.
It’s very simple. You take a jar, I used a quart mason jar, and put a piece of fruit and some apple cider vinegar in the bottom. Then roll up a piece of paper to make a little cone and put that in the jar. Apparently the little pests aren’t smart enough to fly out of the cone so once they go after the bait, they are trapped. After you’ve caught them, just put the jar in the fridge for a bit and they will drift off to fruit fly heaven…or something like that. Easy!
