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.
Fly maggots are usually found burrowing in their food material which is always something warm, moist, rotting, and disgusting, like garbage or animal (or human) poop. When theyâre ready to pupate and turn into flies, the maggots leave the food material and crawl off to a drier place.Because your worms are crawling around in the kitchen, I think you might have an infestation of stored food insects. know that your âwormsâ are not fly larvae (maggots) because fly maggots are wingless and cannot crawl. You donât say how big your worms are, but a full-grown house fly maggot is still small, about Â¼ inches long. Itâs white and has no head or legs; one end is wider than the other which tapers to a point.
