What are some strategies to control chipmunks?


Quick Answer

Chipmunk populations can be controlled by modifying the environment to discourage their presence, using traps or using gas cartridges. Removal of trees and other features that connect the home to the forest deters chipmunks from entering the landscape. Common rat snap traps placed across a chipmunk's path allow the homeowner to catch the chipmunk and release it in another location. Gas cartridges placed in burrows asphyxiate chipmunks.

The preferred method for controlling small chipmunk populations is using traps. Burrow entrances and woodpiles are prime locations for trap placement, blocking common pathways used by the rodent. Traps should be checked often as pets or other small animals may mistakenly enter the traps and need to be released. Avoid placing the traps near children's play areas since there is a risk a child could set off the trap. The trigger can be baited with pumpkin or sunflower seeds, peanut butter, corn, rolled oats or nutmeats to entice the chipmunk. Set two traps across the path facing opposite directions to increase the opportunity for catching the chipmunk.

Chipmunks can damage lawns, patios and foundations. Their burrows can undermine structural foundations, causing the need for eventual repair or replacement. They eat seeds, flowers, bulbs, fruits and vegetables, making them a nuisance for gardeners.
