What can I do to protect my livestock or pets?
Prevention and early detection are the best defenses against NWS. Watch for wounds that fail to heal or that enlarge over time, contain larvae, or are accompanied by loss of appetite or lethargy.
Producers should inspect their livestock on a regular basis, inspect pens and equipment for sharp objects that can cause wounds, and clean, cover, and treat any wounds immediately.
Pet owners should make sure their pets are protected from ticks and inspect backyards and pet enclosures for sharp objects that can cause wounds.
If you suspect screwworm in your animal, contact your veterinarian, USDA, the Texas Animal Health Commission, or the Texas Department of Agriculture at 800-TELL-TDA immediately.
The best defense against New World screwworm is prevention, vigilance, and early action.
If you suspect screwworm, contact your veterinarian and immediately report the case to the Texas Animal Health Commission. Early detection is critical because rapid reporting helps officials respond before infestations spread to other animals.
What About Wildlife?
New World screwworm does not only affect livestock. Deer, feral hogs, exotic game animals, predators, and other warm-blooded wildlife can also become infested.
People who encounter wildlife should watch for wounds containing visible larvae, unusual swelling, foul odors, abnormal behavior, or animals that appear weak and emaciated. Dead animals generally do not indicate screwworm infestation because the larvae require living tissue.
Suspected cases in wildlife should be reported to the Texas Parks and Wildlife Department. If possible, note the location, species, and condition of the animal. Photographs can assist investigators but should never be obtained at the expense of personal safety.
Because wildlife can help spread infestations across large areas, monitoring wild animal populations is an important part of Texas' response strategy. State and federal agencies are working closely with wildlife professionals to identify cases quickly and prevent further spread.
