Billions of flies to be dumped out of planes in an effort to fight flesh-eating maggot known as "man-eater"

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.

That sounds like the plot of a horror movie, but it is part of the government's plans for protecting the U.S. from a bug that could devastate its beef industry, decimate wildlife and even kill household pets. This weird science has worked well before.

"It's an exceptionally good technology," said Edwin Burgess, an assistant professor at the University of Florida who studies parasites in animals, particularly livestock. "It's an all-time great in terms of translating science to solve some kind of large problem."
