Hi budd!
If you are looking for some "bio" ways against those nasty gnats or fruitflies, try out some left over RED wine in containers around your grow area. Another great one is: pour apple cider vinegar with a little soap in a jar and place it in the area you think is gnat overloaded. The vinegar attract the flies, when they hit the solution the soap prevents them from flying out! Happy growing/huntimg :)
