3 Best Chipmunk Deterrent Sprays 2025 in the United States

Grandpa Gus's Rodent Repellent Spray uses natural Peppermint and Cinnamon oils to deter rodents such as mice and rats. Its natural ingredient composition makes it environmentally friendly and safe for indoor use, avoiding the need for harmful chemicals. This is a significant strength for households with children and pets, as it mitigates the risks associated with toxic substances.

The spray is versatile for both indoor and outdoor applications, which adds to its appeal for comprehensive rodent control in various environments like cupboards, vehicles, and storage areas. The 1-gallon volume ensures ample supply for extensive coverage, reducing the frequency of repurchase.

Its method of application—spraying and letting it dry—makes it convenient, though it requires consistent reapplication to maintain its deterrent effect. While it is ranked highly in its category, it’s essential for users to manage expectations regarding the longevity and potency of the natural oils, as weather conditions and heavy infestations might necessitate more frequent use. This product is best suited for users looking for a natural, safe, and easy-to-use solution for moderate rodent problems.

Plantskydd Animal Repellent is a versatile and effective solution for keeping chipmunks and other herbivores away from your plants. The product is designed to be used year-round, covering a variety of animals, including deer, rabbits, and squirrels. It comes in a ready-to-use liquid spray bottle containing 32 ounces (33.8 fluid ounces to be exact), which makes it convenient for immediate application without needing any mixing or preparation.

One of its strengths is its wide coverage area, as it can protect up to 100 plants that are one foot high each. The application frequency varies, requiring more frequent use during the growing season (every 2-4 weeks) and less often during the dormant season (every 3-6 months), which makes it adaptable to different gardening needs. Additionally, it's biodegradable and made in the USA, which may appeal to environmentally conscious consumers.

However, there are some potential drawbacks. The spray’s odor might be unpleasant to some users, and consistent reapplication is necessary to maintain its effectiveness. Also, the coverage area, while significant, might not be sufficient for larger gardens or more extensive plantings without purchasing multiple bottles. Still, for many gardeners dealing with chipmunks and other small herbivores, Plantskydd offers a reliable and user-friendly option to protect their plants.

Puremint Rodent Repellent uses a natural 5% peppermint oil formula to keep chipmunks, mice, rats, and other rodents away from your home and garden. The spray comes in a large 128 fl oz (about 3.7 liters) container, offering good coverage for both indoor and outdoor use, including spots like yards, flower beds, and even car engines. It’s made in the USA with plant-based ingredients, which makes it safer for people, pets, and plants compared to harsh chemical repellents.

The formula is liquid-only, so it won’t clog the sprayer, allowing for easy application without frequent maintenance. Peppermint oil is known for its strong scent that rodents dislike, although the product does not specify exactly how long the repellent lasts after spraying, so regular reapplication may be necessary to maintain effectiveness. The natural ingredients and the mint scent make it a more environmentally friendly choice, but those seeking a quick or long-term solution might need patience and consistent use.

This product is a solid option for those who prefer a natural, safe approach to rodent deterrence and want a large quantity for broad coverage.
