It starts with a piece of paper.

In my home, it happens at least once every summer. I throw something into the trash or the compost bucket, and a cloud of fruit flies rises up. Years ago, the sight would fill me with despair. Since I wasn't going to kill them, I usually found myself miserably tolerating fruit flies in my kitchen for the rest of the summer, until the weather turned cold and they disappeared.
Now, I just make this humane, homemade fruit fly trap, and I'm usually fruit fly-free within 2 days.
And yes, flies are animals.
