Veterinarians and humane societies are warning pet owners in Texas and New Mexico following more than 30 confirmed cases of New World screwworm fly infestations. This parasite, which recently reappeared in U.S. cattle, poses a significant threat to dogs, cats, and other mammals by laying eggs in open wounds or mucus. Once hatched, the larvae feed on live flesh and fluids, potentially causing death through infection or organ damage. Experts recommend that owners monitor pets for restlessness, foul odors, or visible movement in wounds. To prevent infestations, veterinarians suggest using prescription flea and tick medications, which can kill the larvae. Meanwhile, the USDA is implementing eradication efforts by releasing sterile male flies into the wild. This includes a $21 million investment in Mexico and a planned $750 million fly factory in Texas to combat the spreading tropical species.
