Screwworms in Texas: What Pet Parents Need to Know
Recent reports of New World Screwworm cases in Texas have many pet owners asking how to protect their pets. Most important to know -- the risk to household pets is low.
The New World Screwworm is not actually a worm. It’s the larval stage (maggot) of a fly that was eradicated from the United States decades ago, but in recent years has been moving north through Central America and Mexico. In June 2026, multiple cases were confirmed in Texas livestock, and a recent case involving a dog in New Mexico connected to the outbreak has increased concern among pet owners.
Screwworm larvae can infest open wounds and damaged skin, causing painful tissue damage. Early prevention and treatment are key.
