They go by many names – pigs, hogs, swine, razorbacks – but whatever you call them, wild pigs (Sus scrofa) are one of the most damaging invasive species in North America. They cause millions of dollars in crop damage yearly and harbor dozens of pathogens that threaten humans and pets, as well as meat production systems.
Although wild pigs have been present in North America for centuries, their populations have rapidly expanded over the past several decades. Recent studies estimate that since the 1980s the wild pig population in the United States has nearly tripled and expanded from 18 to 35 states. More recently, they have spread rapidly across Canada, and these populations are threatening to invade the U.S. from the north.
