some knowledge abt maggots
from Wiki
sourcehttp://en.wikipedia.org/wiki/Maggot
A 'maggot' is the larval stage of the fly life cycle, famous for
eating decomposing flesh. Sometimes "maggot" is used to refer to
the larval stage of any insect.
The fly life cycle is composed of four stages: egg, larva (commonly
known as a maggot), pupa, adult. The eggs are laid in decaying
flesh, animal dung, manure, or pools of stagnant water - whatever
has ample food for the larva, generally in a moist area. After 8-20
hours, the egg hatches and the fly enters the maggot stage. It
begins to feed on whatever the egg was laid on, usually decomposing
flesh. The maggot gorges itself with food until it is ready to
enter the pupal stage, at which point the maggot travels away from
the food source to a moist spot.
so therefore maggots did not appear by itself
there has to be eggs
and b4 eggs, there must be some flys
