Ugh! We are currently experiencing a fruit fly infestation in our house. As you may know, for the past year, I have had a worm farm downstairs in the basement. The purpose of the worm farm is to help us compost our kitchen scraps (non meat and non dairy). I use the compost for my plants, and it is very rich and the plants love it. The worms are pretty low-maintenance, and it has worked well. There isn't much of a smell, and I have even tried them for fishing. I don't like them for fishing though, because I find them to be too weak-bodied. But getting I didn't do it for fishing worms, I did it for the composting.
