Well, a fly is the 4th most cleanest insect since they are constintly cleaning them selves,believe it or not. A cockoroach is the cleanest ANIMAL/INSECT in the world.
I've been hearing that on one of the flies wings there are bacteria that can cause harmful sicknesses and or diseases and on the other wing,bacteria but they are a cure for the harmful ones. it sounds weird but its true. so i guess that its clean and at the same time its not. hope you've got the answer to your question
