I raise my own mealworms and over the last month or so I've had a growing problem with gnats in the mealworm bins. Specifically, they're in the bins with the adult beetles and I don't know how to get rid of them. I tried making traps with apple cider vinegar and a drop of dish soap but the gnats are not attracted to this. Truthfully, I'm not sure what kind of gnats I'm even dealing with. Fungus gnats maybe? Does anyone happen to know what the gnats are and if there's something other than apple cider vinegar that they would be attracted to?
