Things You'll Need
Chipmunks have two breeding seasons: Spring and summer. After 31 days of gestation, the females bare a litter. Young do not leave the burrow (in this case, possibly your walls) for a month. Be wary of removing chipmunks or sealing up holes when babies may be in your walls. Not only is it inhumane to kill the babies slowly this way, it may also cause other pests to enter your home.
Chipmunks are among the smallest members of the squirrel family. They typically measure 10-inches or less in length, and are often identified by their rust-colored bodies and dark stripes on their back. They create extravagant burrows sometimes reaching more than 30-feet long. These omnivorous rodents eat grains, nuts, seeds, fungi and insects. They prefer areas with access to food and protection such as railroad timbers and stone walls. They may find shelter within walls to build nesting sites or use as part of their burrow.
Place peanut butter mixed with oatmeal in the "bait" area of the live trap. Live traps vary, but the "bait" area is typically in the back.
Place the live trap outside the entrance hole the chipmunks use to gain access to your walls.
Contact your local wildlife authority regarding releasing the chipmunks upon capture. State laws vary, but in many cases it is illegal to release animals without a permit.
Release the animal at least a mile away from your home after gaining permission from your local wildlife authority.
Seal the holes where the chipmunks were gaining access after you are sure no more are left inside. Use caulk or expanding foam where appropriate; use wire screen on larger openings.
