USDA builds $750 million fly factory in Texas to fight livestock pest, the New World Screwworm.

The USDA is constructing a $750 million sterile fly factory in Texas to control the New World Screwworm, a fly that can severely harm livestock and wildlife. The facility, expected to take two to three years to complete, will produce 300 million sterile flies per week, reducing the fly population by preventing reproduction. The USDA will also invest up to $100 million in new technologies and increase border patrols to monitor the spread of this pest.
