Chipmunks may be cute, but they can also be annoying pests. As they gather and store seeds for the winter, chipmunks may deplete your bird feeder, dig up seeds and flower bulbs in your garden, and chew into containers of pet food. Even worse, they can damage the structural integrity of your patio or home by burrowing underneath it. Trapping and killing chipmunks can help protect your property.

Step 1

Cut a 3-inch hole in a small cardboard box. Place the box near the chipmunks' burrow entrance or in their usual path of travel. The box will allow chipmunks to enter while keeping birds and larger animals away.

Step 2

Place poisoned bait (strychnine in a 1/2 percent bait formulation) underneath the box. Place food, such as nuts and seeds, outside the entrance to draw the chipmunks in.

Step 3

Set rat-size snap traps or wire cage traps in the chipmunks' usual path of travel. Place snap traps in a cardboard box with a hole cut out, like the poisoned bait, to protect children, pets and other wildlife from harm.

Step 4

Bait the traps with peanut butter mixed with oatmeal, sunflower seeds or dried fruit. Place the baited traps out for two or three days without setting them; this will help the chipmunk get used to the trap's presence and feel safe going there for food.

Step 5

Release chipmunks trapped in live traps at least a mile away from your home, or euthanize them humanely.

Step 6

Change the environment to make it less attractive for other chipmunks who might want to move in. Store all food and seed in rodent-proof containers, and keep bird feeders 25 to 30 feet away from your house. Remove ornamental shrubbery or dry rock walls that may provide cover for chipmunks.
