New World Screworm (NWS).
Don’t just think it’s a normal maggot… this can infect livestock, wildlife, our pets and even humans.
The pest was successfully eradicated from the United States in the 1960s using the "sterile insect technique" (where sterilized male flies are released to mate with wild females, resulting in unfertilized eggs).However, following a northward spread from South America and Central America in recent years, the U.S. Department of Agriculture (USDA) confirmed the reemergence of New World screwworm in the country. Cases were identified in livestock and pets in Texas and New Mexico, triggering immediate federal and state quarantines, movement controls, and expanded sterile fly releases to contain the spread.
What to do if you suspect an animal or a person has a screwworm infestation:
For Animals: Do not attempt to remove the maggots yourself. Contact a veterinarian immediately, as the infestation requires specialized treatment and the site must be properly quarantined.
There are readily available prescription medications to protect our pets. Your pet may already be protected. Just ask us!
For Humans: Clean the wound and seek immediate medical attention from a healthcare provider or go to an urgent care center.
For the most up-to-date information on containment zones, response playbooks, and reporting procedures, visit the USDA APHIS New World Screwworm page or consult your state's department of agriculture.
