Help I.D. Screwworm on Wild Animals or Pets

If you see live maggots on a live animal,  immediately report the sighting, and do not move the animal. It may be infested with New World Screwworm (NWS).

NWS are flies that lay eggs in open wounds and moist body parts of live mammals. The eggs hatch into maggots that feed on living tissue. They kill the animal if left untreated. The first case of NWS in Texas was found on a calf on June 3, 2026.
