How To Keep Chipmunks Away from Tomato Plants

Wildlife 2

Chipmunks are adorable creatures, but when they start nibbling on your precious tomato plants, they can quickly become a nuisance. In this comprehensive guide, we will explore various methods on how to keep chipmunks away from your tomato plants without causing them harm.


To keep chipmunks away from tomato plants, you can install a small-mesh fence around your garden, plant flowers and herbs that chipmunks dislike, use homemade repellent sprays, and clean up your garden to remove potential food sources. If chipmunks persist, consider using live traps to capture and relocate them. It’s important to regularly monitor your garden and adjust your strategies as needed.

Why Chipmunks Love Tomato Plants

Chipmunks are attracted to tomato plants for various reasons. One primary reason is that they are opportunistic feeders and enjoy eating tomatoes- both red and green. They may also eat other parts of the tomato plant, including leaves and stems. Additionally, chipmunks may be attracted to gardens due to the presence of other food sources, such as birdseed, mushrooms, flower bulbs, plant seeds, and insects.

Effective Strategies to Deter Chipmunks

There are several effective methods to deter chipmunks from tomato plants. Here’s a detailed look at each one:

Physical Barriers

Installing a fence made of hardware cloth or chicken wire with a mesh size of 1/4 inch or smaller can prevent chipmunks from accessing your tomato plants. You should bury the fence at least 6 inches deep and extend it at least 2 feet above ground level to prevent chipmunks from digging under or jumping over it.

Natural Repellents

Plant flowers and herbs that chipmunks dislike, such as daffodils, marigolds, alliums, garlic, peppermint, chives, echinacea, and lavender. You can also create a homemade repellent spray by combining water, minced garlic, and cayenne pepper, and spraying it on your tomato plants. An additional option is to spread coffee grounds around your tomatoes, as chipmunks don’t like their odor.


Scare chipmunks away by using decoys like owl statues or fake snakes. You can also install an ultrasonic device that emits high-frequency sounds to deter chipmunks.

Water Source

Provide a separate water source for chipmunks, such as a shallow dish or pan of water, to discourage them from seeking moisture from your tomato plants.

Clean Up

Keep your garden and yard clean by removing potential food sources and hiding spots for chipmunks, such as fallen fruits, nuts, and debris.


If chipmunks continue to be a problem, consider using live traps baited with sunflower seeds or fruit to capture and relocate them.


Remember that you may need to use a combination of these methods to fully protect your tomato plants from chipmunks. Regularly monitor your garden and adjust your strategies as needed to keep these pesky critters at bay. With these tips, you’ll be able to enjoy a chipmunk-free garden and healthy, thriving tomato plants.
