Screwworm Invades Pets: What Texas Owners Need to Know

Seven New World screwworm cases have been confirmed in the region, including a Texas dog, prompting containment efforts and warnings for pet owners. The parasite can infest any warm-blooded animal through open wounds or natural openings, causing pain and tissue damage; early vet treatment—larvae removal followed by larvicides/insecticides—yields the best outcomes. Daily wound checks, fly control, and quick veterinary contact are key to protecting pets, especially near the border or during travel; while not highly contagious between pets, households with multiple animals should monitor all wounds and report sightings of wildlife or stray animals.
