wild pig
Sus scrofa (feral type) Linnaeus


  • Feral swine (also called wild pigs and feral hogs) are an invasive species rapidly becoming established throughout the country.
  • Feral swine cause significant damage to agricultural crops, forests, private property, and other natural areas.
  • In 2000, it was estimated that the total damage caused by feral swine in the United States was approximately $800 million annually.
  • Feral swine damage is caused by their feeding, wallowing, rooting, and tree rubbing.
  • Damage usually occurs at night and can be severe after only a few nights.
  • Damaged areas are left exposed and open to the establishment of invasive plants.
  • Feral swine can vary greatly in appearance and in size. Feral swine are cross between the Eurasian boar and escaped/neglected domestic swine. Typical fur coloration for true Eurasian boar can be grey to dark brown to black, while domestic breeds can display a wider variety of colors with many defining patterns of striping or spots.
  • Feral swine can carry diseases that threaten livestock, pets, and humans.
  • Feral swine are omnivorous feeders and will consume anything in their path – invertebrates, small mammals and other small vertebrates, eggs of ground-nesting birds, even the young of larger animals such as white-tailed deer. In addition, feral swine compete with native wildlife for valuable resources, such as acorns that squirrels, deer, and turkey depend on during winter months.
