Most people find chipmunks endearing until they begin to undermine the integrity of their property. These prolific diggers create extensive underground tunnel systems that often run alongside home foundations, retaining walls, and under concrete walkways or patios. Over time, this constant excavation leads to soil erosion and structural settling, which causes expensive cracks in your masonry and foundation.
Beyond structural concerns, chipmunks also target your gardens and flower bulbs, often destroying your hard work in a single season. Addressing the problem early is the only way to prevent costly repairs.
Look for small, clean-cut holes about two inches in diameter located near your foundation, logs, or rock piles.
Any new cracks in your sidewalk or porch that suggest hollow ground underneath from tunnel systems.
Watch for dug-up flower beds and missing bulbs or seeds shortly after you have finished planting.
Listen for high-pitched, bird-like "chips" or "chucks" repeated in rapid succession throughout the day.
