where do maggots come from nwhen there is no food around?

Answer 1

The same place they come from when there is food around.

Maggots are fly larva

Answer 2

By "food" I suppose you mean left out human food. Many, in fact most Dipteran don't rely of human food for maggots to feed upon. Flies lay eggs in or on just about anything living. Many plants, roting wood, the nose, ear and eyes of animals. There are many more species of flies than just the ones in your house, an estimated 150,000 species.
