Locusts are grasshoppers that breed quickly and form giant swarms that often turn aggressive. They can travel for hundreds of miles across cropland, destroying vegetation.

Unfortunately, locusts are still a problem in Egypt and many other spots. There is one particularly satisfying way to combat them, however: locusts are edible.
