Try mixing some vinegar with dish soap and fill a bowl with it. True to their Genus epithet "Drosophila", they are vinegar-loving flies. They will land in it and instantly sink, because the dish soap eliminates surface-tension, which normallyallows them to float harmlessly on water. place the bowl next to your enclosures. to maximize the effect, use a yellow bowl- which will add a visual trap to the odor as well. This will also help if you buy fruitflies as feeders, so any that escape will be drawn to the trap and wont spread all over the house.
