• NWS (Cochliomyia hominivorax) is a parasitic fly that lays eggs in and on open wounds and mucous membranes of warm-blooded animals. Once hatched, larvae burrow into healthy tissue and feed on it, causing extensive and often deadly tissue damage. This infestation with larvae is called myiasis.

   

  • NWS can infest livestock, pets, wildlife, occasionally birds, and in rare cases, people.

• NWS has not been detected in the U.S.; however, recent cases in northern Mexico highlight the importance of veterinary readiness. Having authorized treatment options available ensures veterinarians can respond quickly if NWS is suspected in dogs or cats.
