Problems Caused by Chipmunks in Yards Chipmunks are unwelcome in yards for a number of reasons. They spend most of their time foraging for food and creating underground tunnels. These activities destroy lawns, deplete gardens, and can cause structural damage to sidewalks, porch stoops, and even the foundations of houses. Chipmunks hog birdbaths, steal from birdfeeders, and eat newly planted seeds and bulbs, as well. Prevention & Removal Property owners can do things, like erecting fences around yards, to reduce the possibility of attracting the pests. However, individuals may still find chipmunks in yards. When faced with infestations, property owners should contact wildlife removal services, like those offered by Critter Control. Our trained technicians eradicate chipmunk presence and offer tips on avoiding future run-ins.
