Wound myiasis occurs when fly larvae infest open wounds. It has been a serious complication of war wounds in tropical areas and is sometimes seen in neglected wounds in most parts of the world. Predisposing factors include poor socioeconomic conditions, extremes of age, neglect, mental disability, psychiatric illness, alcoholism, diabetes, and ...
The Texas parks department says the maggots will lay eggs in "open wounds or orifices of live tissue such as nostrils, eyes or mouth." Such an infestation is known as New World screwworm myiasis .
Screwworm females lay 250–500 eggs in the exposed flesh of warm-blooded animals, including humans, such as in wounds and the navels of newborn animals. The larvae hatch and burrow into the surrounding tissue as they feed. Should the wound be disturbed during this time, the larvae burrow or "screw" deeper into the flesh, hence the larva's ...

Chrysomya bezziana usually infects livestock causing myiasis. Myiasis is the infestation of tissue (living or dead) on a living mammal by fly larvae. Mammals such as sheep, dogs, cattle, pigs, and even humans can become infested. The adult female will lay her eggs on superficial wounds in live animals preferring wounds that are several days old ...
W. magnifica larvae cause myiasis in mammals, mainly in sheep, but also in cattle, goats, horses, and rarely in humans. In sheep, larvae chiefly infest genitalia or open wounds. In humans, W. magnifica larvae may infest the ear, eye, mouth, [4] or nose, damaging living tissues; [3] they may also infest open wounds, including after surgery.
Once infestation occurs, a dark brown discharge will start to leaking from the wound. As the infestation increases, there is more agitation and inflamed tissue, which is accompanied by unpleasant smells. [16] After the process of clinical diagnosis begins and the myiasis is recognized, then the larvae are easier to identify. Treatment of these ...
