() The U.S. government is preparing to breed billions of flies and dump them out of airplanes over Mexico and southern Texas to fight a flesh-eating maggot.

It’s part of the government’s plans for protecting the U.S. from the so-called “man-eater” maggot that could devastate its beef industry, decimate wildlife and even kill household pets.

The targeted pest is the flesh-eating larva of the New World Screwworm fly. The U.S. Department of Agriculture plans to ramp up the breeding and distribution of adult male flies, sterilizing them with radiation before releasing them. They mate with females in the wild, and the eggs laid by the female aren’t fertilized and don’t hatch. There are fewer larvae, and over time, the fly population dies out.

The USDA expects a new screwworm fly factory to be up and running in southern Mexico by July 2026. It plans to open a fly distribution center in southern Texas by the end of the year so that it can import and distribute flies from Panama if necessary.
