fruit flies ???

I have several corns that I have in Aquariams with screen tops. I made hide/egg laying boxes with plastic shoe boxes with a 3" hole cut in one end. I put peat moss 1" deep and the rest 3/4 full of spagum moss. I try to keep them moist most of the time I live in Arizona( A bit warm and Dry here) but I seem to have reoccuring problems with small nat/ fruit flies or something, They definately fly. I have tried Bio Mite spray but I am sure they are not mites. Any ideas or suggestions?
Thanks

I'm here in Arizona too, and I know exactly what you are talking about. In order to avoid this problem I've made my incubation boxes airtight. A few weren't air tight (kingsnake eggs) and when some of the eggs went bad I ended up with a bunch of little squirmy wormies (maggots laid by those fruit fly critters). Had to separate out the bad eggs and search and destroy all the little worms. Transplanted them to a new container and haven't had problems since.

I wouldn't want to use pesticides with eggs ... most I use is a fungicide with moldy eggs. (white mold on good eggs)
