🪰 What Should Pet Owners Know About the New World Screwworm?
The New World screwworm is a parasitic fly whose larvae (maggots) can infest and feed on the living tissue of warm-blooded animals, including pets, livestock, wildlife, and, in rare cases, humans. These larvae typically enter through open wounds or areas of damaged skin and can cause serious tissue damage if left untreated.
While proper wound care and regular monitoring are essential, flea and tick preventives such as Bravecto® and Simparica® have demonstrated activity against New World screwworm larvae and may help reduce the risk of infestation in dogs.
We encourage pet owners to routinely check their pets for wounds, skin irritation, swelling, unusual discharge, or other signs of infection. If you notice any concerns, contact your veterinarian promptly. Early detection and treatment are critical to achieving the best outcome.
If you have recently traveled to South Texas or Mexico and have concerns about your pet's exposure, we are here to help. Feel free to schedule an examination with one of our veterinarians or give us a call at (806) 794-9000.
