Damage Prevention and Control Methods


  • Produce livestock in confinement.
  • Exclusion fences (net-wire and/or electric), properly constructed and maintained, can aid significantly in reducing predation.
  • Herd livestock into pens at night. 

Cultural Methods and Habitat Modification

  • Select pastures that have a lower incidence of predation to reduce exposure of livestock to predation.
  • Herding of livestock generally reduces predation due to human presence during the herding period.
  • Change lambing, kidding, and calving seasons.
  • Shed lambing, kidding, and calving usually reduce coyote predation.
  • Remove carrion to help limit coyote populations.


  • Shooting from the ground is effective. 
  • Use rabbit distress calls or mimic howling or other coyote sounds to bring coyotes within shooting distance.

Frightening Agents and Repellent

  • Guard dogs: Some dogs have significantly reduced coyote predation.
  • Donkeys and llamas: Some are aggressive toward canines and have reduced coyote predation. 
  • Sonic and visual repellents: Strobe lights, sirens, propane cannons, and others have reduced predation on both sheep and calves.


  • Modified restraining traps (Nos. 3 and 4 with padded, offset or laminated jaws) are effective, humane and are the most versatile control tool.
    Power snares.
  • Foot snares are effective where coyotes pass through or under net-wire fences and in trail sets.  

Other Methods

  • Denning: Remove coyotes from dens.
