7 Best Ultrasonic Deer Repeller 2025 in the United States

This ultrasonic deer repeller set includes two devices designed to keep a variety of animals such as deer, raccoons, squirrels, and cats away from your garden or yard. It uses motion sensors to detect movement up to about 26 feet, then emits ultrasonic sounds along with flashing LED lights to scare animals off without disturbing people nearby. Both the detection range and ultrasonic frequency are adjustable, which allows targeting specific animals effectively.

The repellers operate on solar power with a backup USB-C charging option, making them eco-friendly and reliable even on cloudy days. Their waterproof and UV-resistant design ensures durability against harsh outdoor weather conditions. Installation is straightforward, featuring adjustable poles to place them in the ground or holes to hang them on fences or trees.

While the devices perform best in sunny spots for optimal solar charging, the built-in battery can last up to 30 days. Frequent use may require more regular recharging. Their compact size makes them easy to move around, though coverage might be limited for very large areas. These repellers provide a humane, low-maintenance solution for homeowners who prefer solar power and flexible settings to protect their property from common nuisance animals.

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 X-octenol Solar Powered Animal Repeller offers a solid solution for keeping deer and other unwanted animals like squirrels, foxes, and raccoons away from your garden or outdoor space. It uses ultrasonic sound waves combined with flashing lights and a motion sensor (PIR) to effectively disturb animals’ hearing and sight, encouraging them to stay away. The device is solar powered, which is great for saving energy since it charges during the day and works mostly at night. You can also charge it by USB if needed. Its waterproof ABS casing means it holds up well in rain, snow, or wind, making it suitable for outdoor use year-round.

With a detection range covering about 10 meters and a sensor angle of 110 degrees, it covers a decent area, although very large yards might require multiple units. One standout feature is the five adjustable frequency modes, letting you tailor the ultrasonic signal to better suit different types of animals that may bother your space. Installation is simple, and the unit is compact and lightweight. However, it relies on motion detection to activate, so it works best when animals actually come close to the protected zone.

Using the device continuously for a few weeks usually brings the best results, as animals learn to avoid the area. For those looking for an eco-friendly, low-maintenance way to deter a variety of pests and wildlife outdoors, this repeller is a strong candidate, especially if your space fits within its coverage range.
