Maggot therapy (also known as maggot ebridement therapy, larval therapy, larva therapy, or larvae therapy) is a type of biotherapy involving the intentional introduction by a health care practitioner of live, disinfected maggots (fly larvae) into the non-healing skin and soft tissue wound(s) of a human or animal for the purpose of selectively cleaning out only the necrotic tissue within a wound (debridement) in order to promote wound healing. Maggots are selective about what they consume i.e. they focus exclusively on dead tissue and therefore will not eat living flesh.
