How to keep chipmunks out of garden


Gardening is a rewarding pursuit, but it comes with its challenges, and one of the most common issues faced by gardeners is the invasion of chipmunks. These adorable yet troublesome creatures can wreak havoc on your carefully cultivated garden beds. In this comprehensive guide, we’ll delve into effective strategies on “how to keep chipmunks out of the garden.

Understanding Chipmunk Behavior

To outsmart chipmunks, understanding their behavior is crucial. Chipmunks are diurnal, meaning they are most active during the day. They are also hoarders, collecting and storing food in their burrows. Knowing their patterns allows you to strategize when implementing deterrents.

Identifying Chipmunk Damage

Chipmunks may be small, but the damage they inflict can be significant. From digging up newly planted bulbs to nibbling on tender shoots, these pests can undo hours of hard work. Look for small holes in the ground, disturbed soil, and missing seedlings as signs of chipmunk activity.

Natural Deterrents

For those who prefer eco-friendly solutions, natural deterrents offer a humane way to keep chipmunks at bay. Planting mint, daffodils, or garlic around your garden can create an aromatic barrier that chipmunks find displeasing. Additionally, consider using predator urine, available at garden supply stores, to deter chipmunks effectively.

Creating Physical Barriers

Building physical barriers requires some effort, but it’s a proven method for keeping chipmunks out. Install fences with mesh or netting that extends below the soil surface to prevent burrowing. Make sure the fence is at least two feet high, as chipmunks are skilled climbers.

Repellents and Sprays

Commercial repellents are formulated to deter chipmunks without causing harm. Look for products containing natural ingredients like capsaicin or castor oil. For a DIY approach, mix water, cayenne pepper, and dish soap to create a homemade spray. Apply these solutions strategically around your garden.

Planting Strategically

Chipmunks have preferences when it comes to the plants they target. Choose varieties that chipmunks find less appealing, such as marigolds, geraniums, or daffodils. Interplanting these with your more vulnerable crops can act as a natural deterrent.

Maintaining a Tidy Garden

A messy garden is an open invitation for chipmunks. Remove debris, fallen fruits, and excess vegetation regularly to eliminate hiding spots. Prune bushes and trees to reduce access points for chipmunks, making your garden less attractive to these pests.

Using Ultrasonic Devices

Ultrasonic devices emit high-frequency sounds that are unpleasant for chipmunks but inaudible to humans. Place these devices strategically around your garden, focusing on areas where chipmunks are most active. Keep in mind that these devices may take some time to show results.

Companion Planting Techniques

Companion planting involves strategically placing plants that naturally repel chipmunks next to more vulnerable crops. Consider planting marigolds, nasturtiums, or garlic around your vegetables to create a barrier that chipmunks are less likely to breach.

Harvesting Strategies

Timing is crucial when it comes to harvesting your crops. Promptly harvest fruits and vegetables to reduce the attraction for chipmunks seeking a free meal. Regular harvesting not only deters chipmunks but also promotes a healthy garden.

Natural Predators

Introducing natural predators like domesticated cats or birds of prey can help control the chipmunk population in your garden. Cats, in particular, are skilled hunters and can keep chipmunk numbers in check. Ensure that your chosen predator is safe and compatible with your gardening environment.

Understanding Chipmunk Reproduction

Chipmunks are prolific breeders, and understanding their reproductive habits is essential for effective control. Females can have multiple litters per year, so taking steps to disrupt their breeding cycle is vital for long-term success in keeping chipmunks out of your garden.

Community-Based Solutions

Gardening is a shared passion, and solutions to chipmunk invasions can be found within the community. Engage with local gardening groups, share your experiences, and gather insights from others who have successfully dealt with chipmunk issues. Community collaboration enhances the effectiveness of your efforts.


In conclusion, keeping chipmunks out of your garden requires a comprehensive approach that combines an understanding of chipmunk behavior with strategic planning. By implementing natural deterrents, creating physical barriers, and harnessing the power of natural predators, you can enjoy a thriving garden without the interference of chipmunks.
