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.
Maggot infestation is also called fly blown or fly strike.. Maggots are the larvae of flies. Flies are common in the warmer months and love dead, stinky, and rotting material. They lay eggs, and the eggs develop into larvae that need to eat. They larvae eat dead and rotting tissue and look like small, white grub worms.
