10 Best Squirrel Repellents 2026 in the United States

This Upgraded Solar Ultrasonic Animal Repellent is designed to keep squirrels and various other animals like deer, rabbits, raccoons, and skunks away from your yard, garden, or lawn. It uses motion sensors to detect movement and triggers ultrasonic sounds combined with flashing LED lights, which helps deter animals in a humane way without harming them or your pets. The device covers a detection area of up to 25-30 feet with a 120-degree sensor angle, which should be enough for small to medium-sized outdoor spaces.

Powered by solar energy, it charges during the day and doesn’t rely on batteries, making it eco-friendly and low maintenance. Its IP65 waterproof rating means it holds up well against rain and other harsh weather, so you don’t have to worry about it getting damaged outdoors. Setup is straightforward—just place it in a sunny spot about 9-10 inches above the ground and let it charge for a couple of days before use.

The ultrasonic sound is inaudible to humans and safe for children and pets, which is great if you want a non-toxic way to protect your space. Effectiveness can vary depending on the animal and environmental factors, and it may not fully cover very large areas or persistent critters. Some users might find the initial charging time a bit long, and the device only activates when motion is detected, so animals staying still nearby might not be deterred immediately. This repellent offers an easy-to-use, weather-resistant, and pet-safe solution to keep squirrels and other garden pests away, particularly in small to medium outdoor areas.

The BORHOOD Ultrasonic Rodent Repellent is designed mainly for protecting cars from rodents like mice, rats, squirrels, and even skunks. It uses ultrasonic sound waves combined with LED strobe lights to repel these pests, offering a non-toxic and pet-safe method since the sound frequency is too high for humans and pets to hear. The pack includes two units, which is handy for covering more than one area or vehicle.

This repellent offers flexibility in power options: it can run on AA batteries, via USB charging, or through a direct car power connection, making it versatile for different situations. It features a smart vibration sensor that pauses the device while the car is running, helping save battery life and preventing unnecessary operation. The product is compact and easy to install using included cable ties, suitable for cars as well as indoor and outdoor spaces like garages, storage rooms, or basements.

The device can operate for at least three months on battery power, which is convenient, though battery replacement or charging is necessary for continuous use. While it is weather-resistant enough for car engine compartments, it may not hold up well in extreme outdoor conditions if used outside. This repellent is a solid choice for protecting vehicles or small indoor areas from squirrels and other rodents without using harmful chemicals, but it may require occasional battery maintenance and is best suited for smaller or enclosed spaces rather than large outdoor areas.

The Tomcat Repellents Rodent Repellent Granules offer a convenient way to discourage outdoor rodents like mice and rats from entering or nesting around your property. The product comes in granule form and covers up to 1,000 square feet with each 2-pound container, making it suitable for medium-sized yard areas. It uses an essential oil blend to create a scent and taste that rodents dislike, but it is marketed as having no strong smell that bothers people, which is a plus if you want to avoid unpleasant odors outside. One important safety feature is that it’s designed to be safe for kids and pets, as long as you follow the instructions—this makes it a good choice for families. The granules are rain-resistant, so they hold up well in different weather conditions, but you should reapply every 30 days to keep it effective, meaning some ongoing maintenance is needed. Application is straightforward: just spread the granules around the areas you want to protect, like soil or turf near your house or garage.

While this product works well for mice and rats, it might not be as targeted or effective specifically against squirrels since squirrels can be less sensitive to some repellents. If squirrels are your main concern, you may want to look for repellents specifically formulated for them. In conclusion, Tomcat’s granules provide good coverage, ease of use, and safety for typical rodent problems in outdoor spaces but may not fully address squirrel issues.
