Jumping worms are everywhere, according to a new report by the University of Illinois Extension Service.

Jumping worms are also known as “crazy worms,” “Alabama jumpers” and “snake worms.” Why, you ask? BECAUSE THEY JUMP. The Tribune says,”if disturbed, they thrash violently and may leap around a little — it’s momentarily entertaining, in that scary-nature-show sort of way.”

Besides that, they’re just plain bad for the soil. They’re also tough to fight. They breed quickly and, according to the U of I report, their eggs can survive Illinois winters.
