Solutions

Habitat Modification

  • Exclude from small areas by installing 18-inch high 1/4 to 1/2-inch mesh hardware cloth (hail screen) buried 6 inches below ground.
  • Encourage tall vegetation
  • Reduce seedbearing weedy plants.
  • Keep soils moist through overhead irrigation during day.
  • Prevent digging in seedling gardens by planting cold-tolerant varieties before ground squirrel emergence in early spring.

Repellents

  • None registered

Trapping

  • Box trapping: Cover 50% of trap length to prevent stress to captured animal.
  • Rat sized snap traps. (Place them inside a covered box or bait station with holes 2" wide. The box is to prevent non-target capture and injury.
  • Baits include seeds. (Caution: When using seeds be sure to keep out of sight of birds to prevent bird captures).

 

Shooting

  • Not applicable.

Toxicants

  • Fumigants: These should be used away from human habitation. Read label for species of burrowing rodent.
  • Toxicants: Zinc phosphide treated baits are the most common. Be sure to follow label when using toxicants.
