Myiasis is the parasitic infestation of the body of a live animal by fly larvae (maggots) which grow inside the host while feeding on its tissue.

- Myiasis

Maggot-like fly larvae are of significance in ecology and medicine; among other roles, various species are prominent in recycling carrion and garbage, attacking crops and foodstuffs, spreading microbial infections, and causing myiasis.

The maggot larvae, often used as fishing bait, are known as gentles.

The name blow fly comes from an older English term for meat that had eggs laid on it, which was said to be fly blown.

Other species like Metopia argyrocephala are ovoviviparous, opportunistically depositing hatched or hatching maggots instead of eggs on carrion, dung, decaying material, or open wounds of mammals.

A few can even cause myiasis in humans.

Maggot therapy (also known as larval therapy) is a type of biotherapy involving the introduction of live, disinfected maggots (fly larvae) into non-healing skin and soft-tissue wounds of a human or other animal for the purpose of cleaning out the necrotic (dead) tissue within a wound, (debridement) and disinfection.

The infestation by maggots of live animals is called myiasis.

Black blow fly larvae like many other blow flies exhibit the maggot mass effect: a raise in temperature due to the aggregation of maggots.

P. regina larvae have been shown to be an important organism in myiasis of both humans and animals, particularly in the southern region of the United States.

External sheep parasites include: lice (for different parts of the body), sheep keds, nose bots, sheep itch mites, and maggots.

Fly maggots cause the extremely destructive condition of flystrike.
