Control of Feral Hogs

Scientific name: Sus scrofa

  • Tracks: Pigs leave a splayed two-toed track. Toe Pad Marks on Hind Feet Wild pigs and javelina create cloven but splayed deer-like tracks. Pigs often leave small crescent-shaped dewclaw prints outside and behind the main prints.
  • Colaration: Black to brown, gray or white hair with tail hanging straight down.
  • Wallows: wet, muddy areas where pigs roll in the mud.
  • Rubs: pigs will scratch themselves against trees leaving mud and/or broken bark. It is not unusual for several trees (4-inches in diameter or larger) to be used. Rubs will be a few feet off the ground.
  • Scat is in pellet groups or sausage-like.
  • Pigs leave very narrow trails.
  • Collared peccary or Javelina are native pigs inhabiting central Arizona south and eastward through Southern Texas. Weigh 30 to 60 lbs. Grayish to blackish grizzled hair with whitish to yellowish "collar". Hindquarters are small with very small tail. Upper tusks point down. Have disc or irregular shaped scat.

Damage

  • small or extensive areas of diggings to ground
  • crop damage can be substantial
  • poultry, lambs and goats may be killed.

Legal

Feral hogs are an invasive species in the U.S. Some states however ban and or regulate their capture.

Control Methods

Habitat Modification

  • Three-foot high heavy Mesh (2"x4" welded) wire fences and/or multiple electric wires around gardens and other small areas.

Frightening Devices

None found effective over the long term.

Repellents

None known

Trapping

  • Cage trapping is effective but requires large traps and a great deal of patience. Pigs have been known to get trap wise. Australians claim "Feralmone" lure is effective in drawing them. However, grain and other easily obtainable baits work as well.
  • corral traps
  • foot snares

Shooting

  • Sport hunting can reduce general populations but raises the problem of creating a demand for this invasive species to be encouraged rather than eliminated.

Toxicants

None known

Diseases-Safety

  • Feral pigs carry diseases infectious to livestock.
  • Feral pigs also can harm and kill juvenile animals.

Legal Issues

  • Some states may require a license to control feral pigs due to concerns over killing a farmer's stray pig.
