Chipmunks may look harmless and even cute, but when they invade your yard, garden, or home, they can quickly become destructive pests. From digging burrows under foundations to chewing wiring in attics and walls, chipmunks cause far more damage than most homeowners realize. If you’re searching for how to get rid of chipmunks, the solution requires understanding their behavior, habitat preferences, and proven control strategies.
According to wildlife control studies, chipmunks can create dozens of burrows in a single property, destabilizing soil, damaging landscaping, and increasing the risk of structural issues. This in-depth guide explains how to get rid of chipmunks naturally, humanely, and effectively, whether they’re in your yard, garden, walls, attic, garage, or under your foundation.
Understanding Chipmunk Behavior Before Removal
Chipmunks are territorial rodents that thrive in areas with cover, food access, and undisturbed soil. They are most active during daylight hours and can enter homes through openings as small as 1.5 inches.
Key behaviors that influence removal:
- Strong homing instincts
- Excellent digging and climbing ability
- Food caching habits
- Seasonal activity peaks (spring and fall)
Successful chipmunk control always starts with habitat modification combined with deterrence or exclusion.

How to Get Rid of Chipmunks in Your Yard
Definition and Scope
Yard infestations are the most common chipmunk problem and often the source of further invasion into homes and structures.
Effective Yard Control Strategies
• Eliminating Food Sources
Chipmunks are attracted to fallen seeds, bird feeders, pet food, and unsecured garbage. Removing or elevating feeders and cleaning debris reduces attraction significantly.
• Reducing Ground Cover
Dense shrubs, woodpiles, and rock walls provide shelter. Thinning vegetation removes hiding places that chipmunks rely on for safety.
• Soil Disturbance Techniques
Chipmunks prefer undisturbed soil. Regular raking and soil disruption near burrow entrances encourages relocation.
• Motion-Activated Deterrents
Water sprayers and ultrasonic devices can discourage chipmunks when used consistently.
• Burrow Identification and Treatment
Locate entry holes and treat them with repellents or exclusion materials like gravel and wire mesh.
• Consistent Yard Maintenance
A tidy yard with trimmed grass and minimal clutter is far less attractive to burrowing rodents.

How to Get Rid of Chipmunks in Garden Areas
Definition and Impact
Gardens provide ideal chipmunk habitats due to loose soil, seeds, fruits, and vegetables.
Garden-Specific Solutions
• Raised Bed Protection
Installing hardware cloth beneath soil prevents burrowing into root zones.
• Plant Selection Awareness
Chipmunks favor bulbs, berries, and seeds. Choosing less attractive plants reduces damage.
• Natural Repellents
Garlic, cayenne pepper, and predator urine deter chipmunks when reapplied regularly.
• Netting and Barriers
Covering plants with mesh prevents access to edible portions.
• Soil Compaction Techniques
Firming soil around plants reduces digging.
• Harvest Timing
Prompt harvesting removes food incentives that attract chipmunks.

How to Get Rid of Chipmunks in House Walls
Definition and Risks
Chipmunks in walls pose serious fire and structural risks due to chewing on wiring and insulation.
Wall Infestation Control
• Sound and Odor Detection
Scratching noises and musky odors indicate nesting activity.
• Entry Point Identification
Inspect siding, vents, and foundation gaps for access points.
• One-Way Exclusion Doors
Allow chipmunks to exit without re-entry.
• Sealing After Removal

• Insulation Inspection
Damaged insulation should be replaced to prevent odor attraction.
• Professional Evaluation
Wall infestations often require expert wildlife control.
