I recently set up a Dubia roach colony and I am having a fruit fly problem. I made a food concoction of fish flakes, cat food, and Rep-Cal Calcium and Multivitamins. I also threw in some lemon and lime citrus peels and other fruit and vegetable scraps. The problem is there is a swarm of fruit flies around the rotting fruit and vegetable matter and they are becoming a major problem. Is there a way to get rid of the fruit flies, or should I just remove all the fruit and vegetable matter and strictly feed them the fish flake/cat food mix? What do you guys feed your roach colonies? Also for hydration, I have a water crystal dish in there, but do you guys also mist your colonies? Here's some pics. Thanks in advance.
