I'm in my first year of worm "farming" growing red wigglers in a store bought setup called "wormtopia". The setup is easy to use and produces nice casings from the lower trays while the worms work their way up to the newer scraps. This setup allows for worm production as well as casing production. My fish aren't complaining. Now that it's getting cold up here I'm ready to bring the farm into the basement but it's full of fruit flys. Anyone ever experienced this? Am I doing something wrong? Any suggestions?
