Chipmunks might look adorable as they dart between your garden beds, but to enthusiastic gardeners, they can be quite the nuisance. Whether they’re digging up freshly planted seeds, nibbling on ripe fruits, or burrowing into your flower beds, these little critters can wreak havoc on your hard work.
The good news? You don’t need to resort to harmful traps or chemical repellents to protect your garden. By strategically planting certain species of plants, you can naturally, humanely, and effectively deter chipmunks from making your garden their buffet.
This guide dives into how specific plants can help with chipmunk control while enhancing the beauty of your garden.

Why Use Plants to Deter Chipmunks?
Using plants as a chipmunk repellent is an effective and eco-friendly solution for several reasons:
- Safe for the Environment: Unlike chemical repellents, deterrent plants don’t harm surrounding wildlife or soil health.
- Humane: These solutions gently encourage chipmunks to seek food elsewhere without causing harm.
- Low Maintenance: Once planted, these plants do their job without additional effort, while adding to the aesthetics of your space.
- Sustainable Pest Control: With the right combinations, these natural solutions offer lasting protection.
Whether you’re an avid organic gardener or simply looking for a toxin-free way to protect your plants, deterrent plants are a win-win solution.
Top Deterrent Plants for Chipmunks
Choosing the right plants isn’t just about looks; their scent, texture, and even toxicity can all play a role in keeping chipmunks at bay. Here are some tried-and-tested options to get you started:
1. Daffodils
Chipmunks can’t stand the toxic bulbs of daffodils, making them an excellent protective border around your garden. These hardy perennials thrive in colder climates, making them an ideal choice for the Midwest and Northeast. Bonus? Their bright yellow blooms add a cheery touch to your spring garden.
2. Marigolds
Known for their pungent scent, marigolds are great deterrents for chipmunks. Plant them among your vegetables or around flower beds as a natural shield. With their vibrant orange and gold hues, they’ll brighten up any garden space.
3. Garlic Chives
The strong odor of garlic chives repels chipmunks while doubling as a delicious herb for your kitchen. Plant them in clusters near the edges of your garden to protect vulnerable crops and add flavor to your meals.
4. Mint
With its overpowering aroma, mint acts as a strong natural repellent for chipmunks. However, this plant spreads rapidly, so it’s best kept in containers near vulnerable garden areas. You’ll also enjoy having fresh mint for teas, desserts, or mojitos!
5. Rosemary
This aromatic shrub is a fantastic addition for chipmunk-proofing entry points into your garden. Its woody stems and fragrant leaves discourage these furry intruders while offering a versatile herb for your recipes.
6. Alliums (Onions and Garlic)
The sharp, pungent smell of alliums disorients chipmunks. Use onions and garlic to create a protective border around your garden beds. These plants are as functional as they are flavorful.
7. Native Additions
For gardeners in the Midwest and Northeast, consider incorporating native species like Wild Geranium (Geranium maculatum), Partridgeberry (Mitchella repens), or Pennsylvania Sedge (Carex pensylvanica). These plants are excellent for deterring chipmunks and are well-adapted to the local climate and soil.

How to Plant and Care for Deterrent Plants
To maximize the effectiveness of these plants, proper planting and care are key. Follow these tips to ensure your chipmunk-repelling garden thrives:
- Plant strategically: Place deterrent plants around vulnerable areas, such as vegetable gardens, flower beds, or entry points to your property. A border of daffodils or garlic chives is a simple and effective choice.
- Choose the right soil: Ensure you know the soil and sunlight requirements for each plant. Daffodils, for instance, prefer well-drained soil, while mint can thrive in partial shade.
- Water and maintain: Consistent watering and occasional pruning will keep your plants healthy and effective at deterring chipmunks.
- Monitor and adjust: Keep track of which plants work best in your region, adjusting your selections based on performance and chipmunk activity.
Combining Plants for Maximum Effect
Want to make your garden truly chipmunk-proof? Consider combining several deterrent plants for a layered defense. Here are a few combinations to try:
- Border Protection: Line your garden with a mix of daffodils and alliums for a double dose of chipmunk deterrents.
- Interplanting for Vegetables: Place marigolds among tomatoes, peppers, and beans to protect them from hungry intruders.
- Fragrant Barriers: Use a combination of mint, rosemary, and garlic chives near entry points or around fruit trees.
- Ground-Level Coverage: Add native ground covers like Partridgeberry alongside deterrent plants like alliums to keep chipmunks from burrowing.
These combinations not only improve chipmunk-repelling efforts but also enhance the visual appeal of your garden.
Other Natural Chipmunk Deterrents
While deterrent plants are an excellent start, combining them with other natural methods can offer even better results. Here are a few to consider:
- Physical Barriers: Use fences or netting to block access to your garden beds.
- Ultrasonic Repellents: Devices emitting high-frequency sounds can discourage chipmunks from entering your space.
- Homemade Sprays: Create natural repellents using chili pepper, garlic, or vinegar, and spray them around susceptible plants.
- Remove Food Sources: Regularly clean up fallen fruits, nuts, and seeds to reduce chipmunk attraction.
- Attract Predators: Encourage natural chipmunk predators like cats or birds of prey to frequent your yard.
For gardeners facing larger infestations, these measures can work alongside deterrent plants for a comprehensive chipmunk control strategy.
