A hybrid cross between wild boars and domestic pigs are invading the United States. These “super pigs,” which first spread through Canada are now making their way down into the northern U.S.

A cross-bred "super pig" from Canada is poised to wreak havoc on the environment in the United States and must be dealt with aggressively and immediately, a wildlife expert told Fox News Digital.

Pigs are not native to North America.While they've roamed parts of the continent for centuries, Canada's problem dates back only to the 1980s when it encouraged farmers to raise wild boar, Brook said.

Wild pigs already cause around $2.5 billion in damage to U.S. crops every year, mostly in southern states like Texas. And they can be aggressive toward humans.
