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 ultrasonic squirrel repellent is designed for indoor use in places like houses, attics, garages, and basements. It uses multiple sound frequencies and LED strobe lights to create an uncomfortable environment for rodents, aiming to keep squirrels, rats, and other small pests away without chemicals or traps. The device covers a large area—up to about 3900 square feet—thanks to its 8 speakers placed to emit sound in all directions. It also has a frequency-changing feature to prevent pests from getting used to the noise, which is a smart approach to improve effectiveness over time. The LED display lets you easily switch between different modes to find the best setting for your situation.

Safety-wise, it’s non-toxic and safe for pets and children since it relies on sound and light rather than poisons or sticky traps. It's lightweight and simple to set up, making application hassle-free. Ultrasonic repellents usually work best in open spaces without many obstacles, so effectiveness can vary depending on room layout and pest type. Some users might find the LED lights a bit intrusive, especially in bedrooms or quiet areas.

Since it’s an electronic device, it requires continuous power, which could slightly increase electricity use. If you want a chemical-free, low-maintenance way to discourage squirrels indoors and don’t mind some trial to find the best mode, this repeller could be a good fit.

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.
