Chipmunks tend to prefer rugged ground covered with rocks and brush, but also live near agricultural lands where they damage planted seeds and young plants. Fruit trees also may suffer damage from their feeding, and they also consume nuts, insects, mushrooms, and bird eggs. Food is carried in cheek pouches and stores are placed in the burrow for consumption later, including during the winter when the animal awakens from its hibernation on regular intervals to feed and then return to sleep. Burrows are normally underground, but some species also create nests in trees, which they use part of the day. Adults are capable of living for up to 8 years, but in nature a maximum of 3 to 4 years is normal. Mating is in mid spring, and a single litter per year is normal, with 4 to 8 young per litter.
Normally not a major pest problem, but where they occur they may be controlled with trapping or baiting.
