Trapping with box-type traps is not effective because jackrabbits are reluctant to enter a trap or dark enclosure. Snowshoe hares are susceptible to box-type traps.
Body-gripping and leghold traps can be placed in rabbit runways. Trapping in runways may result in unacceptable nontarget catches. Check for tracks in snow or dirt surfaces to be sure only target animals are present. Placement of sticks 1 foot (0.3 m) above the trap will encourage deer and other large animals to step over the trap while allowing access to jackrabbits or other hares. Be sure to check with local wildlife officials on the legality of trapping (for killing or relocating) hares and jackrabbits and on the legality of using specific traps. Permits may be necessary.
