10 Best Ultrasonic Cat Repellent 2026 in the United States

The Broox 2025 Upgraded Solar Animal Repellent is designed to keep unwanted outdoor animals like cats, squirrels, deer, and raccoons away from your garden or yard using ultrasonic sound and flashing LED lights triggered by motion detection. It covers a detection range of about 20–25 feet with a 110° sensor angle, providing good coverage for typical garden areas. Its power options include solar energy, which is eco-friendly and cost-effective, a USB charging option, and it also comes with 3 AA batteries for versatility.

With an IP65 waterproof rating, the device can handle rain, snow, and sun without damage, making it reliable for outdoor use throughout the year. It operates within a 13.5kHz-45.5kHz frequency range to repel various animals humanely without using chemicals. The repellent offers five frequency modes, allowing customization depending on the type of animal causing trouble. Installation is straightforward, as it can be staked into the ground or mounted on a wall.

One limitation is that the detection range might be somewhat limited for very large gardens, and the ultrasonic sound might be less effective on certain species depending on the environment. Additionally, since it relies on motion detection, it only activates when animals move within range, so it won’t prevent animals from approaching outside its sensor coverage. For those seeking a solar-powered, weatherproof, and easy-to-use ultrasonic repellent to gently keep common outdoor pests away, the Broox 2025 presents a solid option.

This solar ultrasonic animal repellent is designed for outdoor use to keep a variety of animals like cats, dogs, rabbits, deer, raccoons, squirrels, and skunks away from your yard or garden. It is powered by solar energy, which makes it eco-friendly and eliminates the need for frequent battery changes. The device is waterproof with an IP65 rating, meaning it can handle rain and outdoor conditions without damage. Its passive infrared (PIR) sensor detects movement within about 32 feet and a 110-degree angle, triggering a 30-second ultrasonic sound and strobe light combination that disturbs animals' hearing and vision to encourage them to leave. You can adjust the frequency and sensitivity to target different animal sizes and improve effectiveness. However, it has limited success with birds and very small animals, so it’s best placed where problem animals usually appear. The coverage area is decent for a single unit, but using two or more devices is recommended to cover larger spaces fully.

Installation is straightforward, requiring placement in direct sunlight about 9-10 inches from the ground. The product is lightweight and compact, suitable for most outdoor areas like gardens, yards, or farms. While it effectively reduces unwanted animal visits, ultrasonic repellents may not work immediately for all animals and some persistence might be necessary. This repellent is a great choice for those seeking a low-maintenance, weather-resistant solution powered by renewable energy.

This 2-pack solar ultrasonic animal repellent is designed to protect your outdoor spaces from cats and various other animals like deer, raccoons, and squirrels. It covers a decent area with a 30-foot detection range and a wide 110-degree sensor angle, making it suitable for most yards or gardens. The device uses sound waves between 25-45kHz paired with LED strobe lights to gently but effectively keep pests away without harming household pets. With six adjustable modes, including a silent setting for sensitive pets, you can tailor its operation to your specific needs and animal activity.

Powered mainly by solar energy, these repellents have a smart dual power system that offers continuous operation year-round, plus USB-C charging for cloudy days or emergencies. The waterproof design (IP44 rating) can handle extreme weather from freezing cold to hot temperatures, ensuring durability outdoors. Installation is simple with included stakes or hanging options, and the two-device set helps expand coverage with overlapping protection zones.

One downside is the reliance on solar power, which might limit performance in very shaded or consistently dark areas despite the backup USB charging. Also, while it targets a broad range of animals, effectiveness can vary depending on the species and their sensitivity to ultrasonic frequencies. The devices require one AA battery each, which is included, but you’ll want to monitor battery health over time. This repellent suits gardeners and homeowners looking for a humane, low-maintenance way to deter multiple outdoor pests, especially those wanting eco-friendly, solar-powered solutions. It’s less ideal if your yard has too much shade or if you want a device specifically focused only on cats.
