What to know about the New World screwworm fly and its reappearance in the US
The New World screwworm fly, which had been eradicated in the U.S. since 1966, has reappeared in Texas after being detected in Mexico in 2024. The fly's larvae infest open wounds of warm-blooded animals, posing a significant threat to the $17 billion Texas cattle industry. Federal and state officials are monitoring the situation as the parasite spreads, with historical eradication efforts involving sterile male fly releases.
