Blowflies are the most common kind of fly that causes cutaneous myiasis, and the most dangerous species may be found in Central America, South America, and Africa.

These insects don’t really lay their eggs on human skin; instead, they infest other insects like mosquitoes or just deposit them on a surface (like a clothes hanger) where they may later be ingested.

These eggs hatch into stinging, skin-penetrating larvae that may grow to be 2.5 cm in length. Movement, a rash, and sometimes throbbing pain are symptoms; fortunately, they may be treated.

The larva is first subjected to hypoxia, forcing it to the surface where it can breathe, and then it is manually extracted using forceps. Ivermectin is used to treat severe infections.
