Chipmunk Control: Trapping and Repellents

Keeping Chipmunks Out of the Vegetable Garden

Chipmunks eat seeds, bulbs, seedlings, and fruit. They're cute but destructive.

Most Effective: Live Trapping

• Use small live traps (Havahart 1025 or similar).
• Bait: peanut butter, sunflower seeds, oats.
• Place along walls, near burrows, or travel routes.
• Check frequently; release ≥5 miles away (check local laws).
• Not always practical for large populations.

Repellent Options

• Commercial: Critter-Repellent.com – predator urine, capsaicin, garlic-based sprays.
• DIY: Hot pepper spray (1 tbsp cayenne/quart water + dish soap), garlic/pepper blend, or predator urine (fox/coyote).
• Physical barriers: 1/4" hardware cloth buried 6" deep around beds.

Habitat Modification

• Remove brush piles, rock walls, dense groundcover near garden.
• Keep bird feeders far from beds (spilled seed attracts chipmunks).
• Encourage predators: hawks, owls, snakes (provide perches, rock piles).

What Doesn't Work Well

• Mothballs (toxic, illegal for outdoor use).
• Ultrasonic devices (no evidence).
• Flooding burrows (temporary, inhumane).

Integrated Approach

Combine trapping (for immediate reduction) + repellents (for ongoing deterrence) + habitat modification (long-term). Persistence is key—chipmunks are territorial and recolonize quickly.
