I was thinking of saving money by catching fruit flies from my compost bin. I was thinking of putting some rotten fruit in a container and leaving it in the bin for a couple of days, so the flies can lay their eggs on it. Then I would close up the container and let the flies hatch. I figure this way I wouldn't have to worry about pesticides, but I was wondering if there were other problems I wasn't thinking of?
I get a ton of soldier flies in there, too.
