Sorry for the rather gross photo! But -- have you ever had a fruit fly infestation? We get them occasionally in the summer, but we've had a bad one over the past few weeks, despite the fact that it's WINTER and I don't have any fruit or other produce sitting out in my kitchen! So this post is really just a quick tip about what to do if you find your self in the same boat that I was in.
The first thing is to find the source of the infestation. You might think there isn't anything, but there is. In our case, my son apparently threw away a banana peel in his bathroom wastebasket two weeks or so ago. (He's supposed to empty that wastebasket, too -- yeah, didn't get done.) So we got rid of the banana peel, but we still had fruit flies in the house.
To get rid of them, I filled a shallow container about a third full with apple cider vinegar. To that I added a few drops of dishwashing liquid. Then I covered the container very tightly with plastic wrap, and poked some holes in the top. The holes need to be big enough for the fruit flies to find, so they can't be too small. Then I set the container out on the counter.
Twenty-four hours later, there were 22 dead fruit flies in the vinegar, and I'd killed 3 more that were hanging around nearby and were apparently drugged by the scent. Now, if you'd asked me how many fruit flies I thought there were in the house after the banana peel had been tossed, I'd have said 3 or 4. I had NO IDEA we had this many! Gross, just gross. And yeah, it's really gross seeing their dead bodies in that container. But, it had to be done.
After twenty-four hours, I tossed the old mixture and set out a new container. You have to keep a dish of the mixture out for a few days to make sure you catch any fruit flies that have just hatched. I'd have sworn there weren't any more of those suckers in the house, but after a few hours, there were 3 flies in the solution.
Again, sorry for the gross picture, but I wanted to show you that this fruit fly trap really works! Apparently, fruit flies are really dumb, and after they fly into the container through one of the holes, they can't figure out how to get back out again, and eventually they drown. So, yeah, very gross, but very effective. Just a quick tip from my kitchen to yours!
