One of those fly tape sticks that you hang from the ceiling? I remember when we had a housefly problem, we sprayed nearly every room with fly killing spray, I think it was Raid since we didn't know exactly which room they were "based" in. Well, there were no more houseflies, we had to clean up housefly bodies the next few days though.
