If however, you are talking about some maggots in a bowl of wet food (either canned food or dry food which got wet or which you deliberately added fluid to) it is a different matter. Maggots come from flies eggs and they take some set period of time to hatch from the eggs.
Maggots generally doesn't do anything harmful to the human body. Maggots ONLY eat dead flesh and try its best to keep away from clean flesh. If you find maggots in your home, â¦ i'd advise you to leave em there until they grow up to grown adult flies and leave your house. I say again, they will not harm you.
