An odd wound? Call your vet.
Screwworm is a fly pest. Its young can grow in wounds. A vet or animal health official must check a suspected case.

What to look for
Watch for wounds that look wrong, maggots in a wound, or a change in how an animal acts. These signs do not prove screwworm. They do mean you should get help.
What to do next
For livestock or pets, call the Texas Animal Health Commission (TAHC) right away at 1-800-550-8242. Contact your vet for care. Describe the animal, wound, and location. Follow their directions for reporting and treatment.
Before moving animals
Texas has rules for animals leaving infested areas and entering from other affected states. Maps and rules can change. Check the current TAHC guidance with your vet before loading a trailer.
For young helpers
Tell an adult right away if you spot a wound. Do not handle maggots, treat the wound, or try to catch the animal on your own.
