Some maggots which eat dead, but not live, flesh have been used medicinally, being introduced into wounds to clean them. Other maggots, such as the screwworm, eat live flesh.

The type of maggots found on a corpse can be used by forensic scientists to give an indication of the time elapsed since, and place of, death.

Maggots are a popular bait in angling, and a food for carnivourous pets such as reptiles or birds.
