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.
Flies breed and ultimately lay their eggs, which become maggots. Flies breed mainly in decaying meat and fish. This means that if you want to prevent maggots from being able to hatch, you'll need to stop allowing excess meat and fish into your trash. Here are a couple solutions for attacking the source of the problem.aggots are fly larvae, and they can be hard to eliminate. Whether they have infested your trash can, your home or you have somehow managed to have them as part of an infection on your body (myiasis), you need to know how to kill maggots in order to successfully get rid of these creatures.
