10 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.

This 2-pack ultrasonic animal repeller by X-PEST is designed to keep deer and other unwanted animals away from your yard using ultrasonic sound and flashing LED lights triggered by motion detection. It’s great for outdoor use because it’s waterproof (IP65 rating) and made from durable ABS plastic, so it can handle rain and rough weather. One nice feature is its dual power options: it charges with solar energy during the day but also supports USB fast charging, ensuring it works day and night. It even alerts you when the battery is low, so you don’t have to guess when to recharge.

The device covers a decent area and lets you adjust both the sensitivity and ultrasonic frequency, which helps tailor it to different animals and environments. Since ultrasonic waves are inaudible to humans, it won’t bother you or your neighbors. It requires two AA batteries (included), which adds convenience but means occasional replacement. The compact design allows for flexible placement — stuck in the ground or hung up — letting you cover wider spaces as needed.

This repeller is suited for homeowners wanting an eco-friendly, low-maintenance way to protect gardens, lawns, or small farms from deer, cats, raccoons, and similar intruders. Its mix of solar and USB charging, motion sensor, and adjustable settings make it a practical choice for those looking to keep animals away without chemicals or traps.
