Chipmunks are amusing to watch as they scurry about our lawns; though they can cause damage to our landscape with their burrows and appetite for seeds, berries and other vegetation which grows in the yard. The chipmunks burrow entrance is usually 2 inches in diameter and can be as deep as 30 feet. The entranceway does not have a mound, as not to attract predators, and are usually located near objects such as stones, tree stumps, wood piles or foundations so the entrance remains hidden. Their extensive burrows have separate chambers for food storage, sleeping, and even a 'restroom' to accommodate their needs.

During the onset of cold weather, they will enter a ‘restless hibernation’ in which their heart rate and body temperature decrease and they wake every few days to feed off of their food stockpile only to go back to sleep again. Their diet consist of grains, nuts, berries, seeds, mushrooms, and insects; though may also include small birds, eggs and frogs among other items.

Chipmunks: Damage to properties

Digging bulbs and seeds: In their search for food, chipmunks will sometimes dig up bulbs and seeds causing damage to the garden. This can be remedied by applying cayenne pepper to the area on a normal basis. The smell will not only deter chipmunks, but will keep other unwanted animals away. A chicken wire fence can also be used as a barrier, though does require maintenance so the leaves, stems and roots of your bulbs do not get caught up in the wire meshing.

Burrows:
It is rare that a chipmunks burrow would become a problem in the lawn, though sometimes the damage needs to be addressed (usually if the burrows are causing structural damage). To keep chipmunks out, bend hardware cloth into an 8"-12" long L shape, bury the hardware cloth about a foot from the point of entry you want to block off. This will prevent the chipmunk from burrowing in specific areas.

Other Control Methods:
Chipmunks may try to enter through gaps of the foundation, vents or other ground-level openings. These spaces can be patched or screened to prevent entry.
