Rodents 5

Peppermint oil, known for its strong, refreshing aroma, is not just a popular ingredient in candies and toothpaste. It’s also an effective, natural deterrent for chipmunks. In this comprehensive guide, we’ll explore how to use peppermint oil to repel chipmunks, the science behind it, and other effective natural deterrents you can use in combination with peppermint oil.


To use peppermint oil to repel chipmunks, purchase pure peppermint essential oil and soak cotton balls in it. Place these soaked cotton balls in areas where you’ve noticed chipmunk activity, such as near plants or entry points to your home. Replace the cotton balls every few weeks or when the scent starts to fade. Always use the oil responsibly as it can be toxic to pets and children if misused.

What Makes Peppermint Oil Effective?

Chipmunks, like many rodents, have a keen sense of smell. The strong scent of peppermint oil is displeasing to them, making it a useful tool in keeping these critters at bay. It’s a natural and non-toxic option, making it safe to use around your home and garden.

How to Use Peppermint Oil to Repel Chipmunks

Here’s a step-by-step guide on how to use peppermint oil as a chipmunk deterrent:

1. Purchase pure peppermint essential oil. You can find this in most health stores or online.

2. Soak cotton balls in peppermint oil. Use about 3-5 drops of oil per cotton ball.

3. Place the soaked cotton balls in chipmunk hotspots. Focus on areas with noticeable chipmunk activity, such as near plants, around your garden, or near entry points to your home.

4. Regularly replace the cotton balls. The scent will fade over time, so replace the cotton balls every few weeks or when the scent starts to fade.

Safety Considerations

While peppermint oil is a natural solution, it’s important to use it responsibly. It can be toxic to pets, particularly dogs and cats, if ingested or inhaled in large quantities. Also, peppermint oil should not be used on children less than 30 months old due to the risk of adverse reactions. Always consult with a healthcare professional or veterinarian when using essential oils around children or pets.

Complementary Natural Deterrents

For a more comprehensive chipmunk control strategy, consider combining peppermint oil with other natural deterrents. Essential oils such as eucalyptus, lemon, clove, and cinnamon are also known to repel chipmunks. Creating a spray with these oils and peppermint oil can create a more potent deterrent.

Anecdotal Evidence

While there is no definitive scientific research or case studies supporting the use of peppermint oil for chipmunk control, anecdotal evidence suggests it works. Many homeowners have reported success with peppermint oil in keeping chipmunks and other rodents away from their homes, sheds, and vehicles.


Peppermint oil can be a useful tool in your arsenal against chipmunks. It’s natural, non-toxic, and easy to use. However, remember that it’s just one tool, and comprehensive chipmunk control may require a combination of methods. Always consult with a professional if you’re dealing with a large chipmunk population or if you need more advice on using peppermint oil safely and effectively.
