From umbilical lesions to tick bites, New World screwworm (NWS) infestations can start from many kinds of wounds. Laying eyes on your animals is the key to protecting them from this pest. If you observe these signs in your animals:
1. Do NOT move the animal (even to the vet clinic)
2. Report to the TAHC 1-800-550-8242
3. Don't panic. This is a highly preventable and treatable condition.
