Chipmunks continuously make chirping noises as they run and climb around. Chipmunks constantly search for food, often eating right out of palm of your hand.
Primary nests for Chipmunks are in tree cavities, hollow logs or underground dens. They feed on acorns, nuts, seeds, insects and berries.
Chipmunks will not commonly nest inside homes, buildings, and yards. If there is a large enough opening in the foundation or building, they will enter following insects inside and sometimes feed off of pet food. Locating and sealing any entry points of the home or building will prevent chipmunks and other rodents entering inside.
