The US government plans to release billions of sterilized male New World screwworm flies over Mexico and southern Texas to combat a flesh-eating pest threatening livestock and wildlife. This method, previously successful in eradicating the pest, involves breeding sterile flies and distributing them via airplanes. A new facility in southern Mexico is planned by July 2026, while a Texas distribution center will open by year's end. This environmentally friendly approach aims to prevent the pest from devastating the US beef industry and causing harm to animals, including humans.
