10 Best Ultrasonic Deer Repeller 2025 in the United States

The Maxfetched Solar Animal Repellent is a versatile ultrasonic device designed to keep a variety of animals away from your outdoor spaces, including deer, squirrels, raccoons, cats, and birds. It uses a 3-in-1 system combining ultrasonic waves, strobe lights, and alarm sounds, triggered by motion within 30 feet and a wide 110° detection angle. This broad detection helps cover yards and gardens effectively, though larger areas might need multiple units for full coverage.

The repeller offers 6 adjustable ultrasonic frequencies, allowing you to target specific animals and rotate settings to avoid pests getting used to it. Its dual power options—solar and USB charging—with a 15-day battery life add convenience for continuous outdoor use. The weatherproof design ensures durability against rain and heat, making it reliable for different climates. The ultrasonic waves are mostly effective against small to medium animals, so very large deer might require additional measures. While the strobe lights and alarms add extra deterrence, some users might find the alarm sounds disruptive if used at night; however, there is an option to turn them off during those hours.

Installation is flexible with wall mount or ground stake options, fitting well into various setups. For those needing a multi-animal repeller that covers a decent outdoor area with solar charging, this product performs well. For extensive properties or large deer populations, it may be beneficial to supplement it with other methods.

The Sunnydaze Solar-Powered Ultrasonic Animal Repeller offers an effective and versatile solution for keeping various animals away from your garden or yard. With five different modes, it utilizes ultrasonic sound frequencies and a flame light to deter pests like deer, cats, dogs, raccoons, and more within a 26-foot detection range. The repeller has a 110-degree sensor angle and comes with a PIR motion sensor to detect animal movements accurately.

It provides multiple height options with two optional pole sections, making it adaptable to different environments and needs. The device is durable and weather-resistant, featuring an IP44 waterproof rating, which ensures it can withstand rainy conditions. You can power it through solar energy or a USB cable, making it convenient and environmentally friendly, though the USB adapter is not included in the package. One notable feature is the LED flame light, which operates only at night or in low ambient light, adding an extra layer of deterrence.

Some users may find the need to charge it for 6 hours via USB or 12 hours in full sunlight before use to be a drawback. Also, while it provides good coverage, those with larger areas might need multiple units for complete protection. The device is lightweight and made from durable ABS plastic, but its effectiveness can be subjective based on specific pest issues and environment. The Sunnydaze repeller is suitable for homeowners looking to protect their gardens from various animals.

This 4-pack ultrasonic deer repeller set uses a combination of high-frequency sound waves and flashing LED lights to keep a variety of animals like deer, cats, raccoons, and squirrels away from your garden or yard. Thanks to its passive infrared sensor, it detects movement within 20-25 feet and a wide angle of up to 150 degrees, triggering the deterrent to activate only when needed. The dual power options—solar charging and USB charging—add flexibility, though the device works best with regular sunlight exposure to keep its batteries charged.

Its IP65-rated waterproof design means it can handle rain and temperatures from -20°C to 65°C, making it suitable for most weather conditions. Installation is simple, with stakes to place it about 9-10 inches above the ground for optimal detection. The device is designed to be safe and humane, effectively deterring animals without harm, though the small unit size may limit coverage per device, so multiple units might be necessary for larger areas.
