The Best Ways to Protect Your Garden from Chipmunks

Chipmunks can cause havoc in gardens by digging holes, eating flower bulbs, and destroying vegetable plants. If you have noticed signs of chipmunk activity, such as small tunnels, missing seeds, or chewed-up vegetables, it’s time to take action. From physical barriers to repellents, there are multiple ways to keep these critters away. The best approach combines deterrents, habitat modification, and effective trapping methods.

Use Physical Barriers to Block Access

Physical barriers prevent chipmunks from burrowing into your garden beds and flower beds.

• Hardware Cloth: Bury ¼-inch wire mesh hardware cloth at least six inches underground around plants.
• Bulb Cages: Protect flower bulbs by planting them inside wire mesh cages.
• Fences with Hardware Cloth: Surround your vegetable gardens with a sturdy fence at least 12 inches high.
• Pipe for Chipmunks: Placing metal or PVC pipes around vulnerable plants can discourage burrowing.
• Cover Crops with Netting: Bird netting can help keep chipmunks away from low-hanging vegetables and fruit trees.

Use Strong Smells to Repel Chipmunks

Chipmunks have a strong sense of smell, making odor-based repellents effective.

• Cayenne Pepper & Chili Powder: Sprinkle around garden beds and flower beds.
• Castor Oil Mix: Spray a mixture of castor oil and water on the soil.
• Predator Urine: Soak cotton balls in predator urine and place them near chipmunk holes.
• Onion Bulbs & Garlic Plants: Plant allium plants like garlic and onions as natural deterrents.
• Spray Bottle with Soapy Water: Soapy water irritates their sense of smell and taste.

Modify Their Habitat to Make Your Garden Less Inviting

Reducing food sources and shelter can push chipmunks to relocate.

• Remove Bird Feeders or Use a Bird Feeder Pole: Keep food sources out of reach.
• Eliminate Wood Piles & Scrap Wood: Chipmunks hide in stacked materials.
• Keep Animal Feed Containers Sealed: Prevent chipmunks from accessing pet food.
• Fence Off Yard Areas: Close gaps and block entry points.
• Clear Fallen Seeds & Fruit: Regularly clean up sunflower seeds, piles of seeds, and dropped fruit.

Effective Trapping Methods for Chipmunks

Traps can be a humane method or a quick solution.

• Humane Trap: Use live traps to catch and release chipmunks far from your home.
• Snap Traps & Rat Traps: These work like mouse traps for quick removal.
• Sticky Traps: Not recommended due to the risk of harming non-target animals.
• Thiram-Based Repellent & Liquid Fence Deer and Rabbit Spray: Apply these deterrents to keep chipmunks from chewing plants.
• Cold Water Bucket Method: Some people use a bucket of ice water to trap chipmunks.
