10 Best Squirrel Repellent 2025 in the United States

Grandpa Gus's Rodent Repellent Spray uses natural peppermint and cinnamon oils to create a scent barrier that discourages rodents like mice and rats from nesting or chewing, which can be helpful around homes, vehicles, and stored equipment. It comes as a 16-fluid-ounce oil-based spray mixed with water, allowing it to spread quickly without leaving stains. This product is designed mainly for indoor use and works by leaving a dry residue that rodents avoid or get on their paws, making it effective for protection against chewing damage. The fresh peppermint scent doubles as a mild air freshener, which some users may find pleasant.

The spray can be applied to both small and large areas, but reapplication is necessary if the treated surface becomes wet, dusty, or exposed to heat, which may limit the duration of protection. While the product is natural and water-based, it’s important to keep it away from children and pets, suggesting caution in homes with young kids or animals. The application process is simple—just shake and spray on dry surfaces, waiting for it to dry before a second coat.

This spray is not specifically formulated for outdoor use or wide open areas where squirrels often roam, so it might be less effective for those looking to repel squirrels in gardens or yards. Being natural and water-based is an environmental plus, but disposal instructions indicate the container is non-refillable, which is less eco-friendly. If you want a scent-based, easy-to-use indoor rodent repellent with natural ingredients, Grandpa Gus's spray can be a good choice, especially for keeping mice and rats away from wires and nests. However, if you need something stronger or for outdoor squirrel control, you might need to look for more specialized options.

This solar ultrasonic animal repellent is designed to keep squirrels and other small animals like rabbits, raccoons, and deer away from your yard or garden using sound waves and strobe lights. It detects movement up to 32 feet within a 110-degree range and then emits a 30-second ultrasonic signal combined with flashing lights to disturb the animals without harming them. Since it is solar powered and waterproof (IP65 rated), it can run outdoors continuously with minimal maintenance, making it energy efficient and environmentally friendly.

The device is easy to set up—simply place it in direct sunlight about 9-10 inches off the ground and adjust the settings to match the target animal's size. To cover larger areas effectively, multiple units may be needed to avoid blind spots, as a single device covers a limited zone. It is safe for pets and children because it uses non-chemical methods, though pets sensitive to ultrasonic sounds might be affected, so careful placement is advised. The device requires an initial full solar charge before use, and keeping the solar panel and sensor clean helps maintain optimal performance.

The combination of ultrasonic sound and flashing lights provides a strong deterrent, but animals may become accustomed to it over time if the device is not repositioned or supplemented with other methods. This repellent is suitable for homeowners seeking a humane, low-maintenance solution to protect outdoor spaces from squirrels and similar pests.

Plantskydd Animal Repellent is a liquid solution designed to deter a wide range of herbivores, including squirrels, from damaging plants. It can cover around 500-600 plants up to one foot high, making it suitable for gardens with numerous small plants or shrubs. The repellent works year-round and remains effective through both growing and dormant seasons, with application frequency ranging from every 2-4 weeks during growth to 3-6 months when plants are dormant.

One of its advantages is that it is biodegradable and unscented, making it safer for pets, children, and the environment compared to chemical-based repellents. The product is rainfast within 24 hours, meaning it won’t wash away easily in light rain, helping maintain its effectiveness. The jug does not come with a spray trigger, so you will need to purchase or use your own spray equipment for application, which might be inconvenient for some users.

This repellent represents a good choice for gardeners looking for an environmentally friendly and versatile option, especially if you have a variety of plants and want long-lasting protection. Just be prepared for a bit of extra effort when it comes to applying the liquid.
