4 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.

Grandpa Gus's Natural Rodent Repellent Powder offers a plant-based solution to deterring mice and rats. The ingredients are natural, which is a plus for users looking for an eco-friendly option. It works by irritating the nasal passages of rodents, encouraging them to leave the treated area. The product is versatile, usable both indoors and outdoors, making it suitable for homes, gardens, and various outbuildings.

It does require reapplication every 30 days or sooner if it gets wet, which could be seen as a maintenance drawback for some users. The application method is straightforward; you simply sprinkle the powder around the perimeter or place it on a paper plate in rodent-prone areas. This could be convenient for users who prefer a no-mess, no-fuss approach without the need for traps.

The product is safe to use around pets and plants, which adds to its appeal. Its effectiveness is well-regarded, but it might need to be complemented with other Grandpa Gus's products for maximum effect. Users looking for a natural, non-lethal deterrent may find this product particularly beneficial, though those with large areas to cover might need multiple containers.
