Biology

  • Diurnal
  • Not a true hibernator but will den up for extended periods of time during severe winter weather
  • Den dweller, often in stone walls

Sign

  • 2-inch clean round hole, sometimes a second hole is nearby
  • Alert whistles can be heard
  • Easily seen scurrying around searching for nuts
  • Tracks: 
    • 4 toe Pad Marks on Hind Feet
    • Size of Front Feet 1/2 inch X 1/2
    • Hind and Front Pairs of tracks together when animal is bounding. Front feet usually diagonally placed behind hind feet.

Damage

  • Seeds lost or cached, flower bulbs, pet food
  • Gnawing on maple syrup tubing
  • Burrowing can undermine pools, sidewalks, and embankments
  • Prey upon young birds and their eggs.

 

Chipmunk Control

Habitat Modification

  • Remove food sources such as bird feeders, seed bearing trees.
  •  Remove harborage such as stone walls and replace with wood or brick or interlocking stone.
  • Exclusion: Use 1/4-inch (6-7 mm) hail screen mesh; rodent proof stored seeds or pet food.

Frightening Devices

None effective

Repellents

  • Both taste or area have limited effect.

Toxicants

  • None registered. They would also be dangerous as this species would cache the toxicant.

Trapping

  • Cage Trapping--
    • Sherman traps
    • Cage traps
  • Kill Traps
    • Rat snap traps
    • Clamshell traps

Shooting

  • Not practical
