Feral Swine Damage Control Strategies

Feral swine have been called the “rototillers” of nature. Their long snouts and tusks allow them to rip and root their way across America in search of food. Unfortunately, the path they leave behind impacts ranchers, farmers, land managers, conservationists, and suburbanites alike.

Found in at least 35 states with a population of more than 5 million, feral swine cause approximately $1.5 billion in damages and control costs in the United States each year, with at least $800 million of this estimate due to direct damage to agriculture. The damage caused by feral swine seems endless and includes the following:

  • Destroying native habitats, crops, lawns, and river banks through rooting and wallowing
  • Eating and destroying agricultural crops
  • Competing with native wildlife for food and other resources
  • Carrying or transmitting over 30 diseases and 37 parasites
  • Contaminating human food sources and water supplies
  • Destroying property and fences
  • Eating ground nesting birds and other small wildlife
  • Consuming livestock feed and supplements and fouling water sources
  • Colliding with vehicles

The APHIS Wildlife Services (WS) program provides technical advice to landowners, state agencies and others, as well as direct management assistance for feral swine problems in more than 30 states. This is often necessary because hunting alone cannot resolve feral swine conflicts with humans. WS experts provide a 3-pronged approach that involves management, disease surveillance, and research.

WS researchers at the National Wildlife Research Center (NWRC) support this effort by studying a variety of issues such as feral swine behavior and ecology, disease transmission, and the development of new management tools and techniques. Recent efforts have evaluated the effectiveness of an oral toxicant bait and swine-specific bait delivery systems, as well as existing trap designs.
