10 Best Ultrasonic Mice Repellents 2026 in the United States

The BORHOOD Ultrasonic Pest Repellent is a plug-in device designed to keep mice, rats, squirrels, and various insects away from your home or office using sound waves between 25kHz and 65kHz. This wide frequency range helps target different pests effectively without using traps or harmful chemicals, making it a cleaner and more humane option. It works best in open indoor areas like kitchens or basements, but because ultrasonic sound doesn’t pass through walls or furniture, you’ll need one unit per room for good coverage.

The device offers three modes: two quieter settings for daily use and a louder, more intense one for tougher pests, which should be used only when no people or pets are nearby. It’s energy-efficient, using very little power, and easy to operate with a clear LCD screen that shows the active mode. Designed with families in mind, it’s safe around children and most pets (except pet rodents like hamsters). However, it may take a few weeks to see full results, and you might notice more pest activity initially as they move away.

While it doesn’t eliminate pests instantly, this device provides a low-maintenance, safe choice for those looking to reduce indoor pest problems without traps or chemicals.

This ultrasonic pest repellent from BORHOOD offers a humane and energy-efficient way to deter a wide range of pests including mice, rats, squirrels, insects, and spiders. It works within a frequency range of 25kHz to 65kHz, which is broad enough to target various pests effectively. The device is designed for indoor use in open areas like kitchens, basements, and garages, but because ultrasonic waves can't pass through walls or heavy furniture, you’ll likely need one unit per room for full coverage. It plugs into a standard outlet, consuming very little power (3–5 watts), which makes it convenient for continuous use without increasing your electricity bill much.

One of its standout features is the three adjustable modes: two quiet modes for daily use and a louder mode meant for unoccupied spaces when pests are particularly stubborn. This flexibility lets you customize how the device works depending on the situation. The clear LCD display helps you easily see which mode is active and monitor the device’s status. Safety-wise, it’s family and pet-friendly, suitable around dogs, cats, and children, but it’s not recommended if you have pet rodents like hamsters.

The build uses durable ABS plastic, which is sturdy enough for indoor use, though it’s not designed for outdoor exposure. Users should be patient since it can take several weeks (3-4) to notice a significant reduction in pests, and an initial increase in pest activity is normal as they leave their nests. Some users might find the coverage limited for larger or multi-room homes due to ultrasonic wave limitations. This device suits homeowners or office users seeking a low-maintenance, chemical-free pest control option indoors.

The Cvtayn Upgraded Ultrasonic Pest Repellent covers indoor areas up to 1600 square feet per unit, making it suitable for rooms like bedrooms, kitchens, and garages. It operates within a broad frequency range (10kHz - 65kHz) that targets various pests, including mice, roaches, spiders, and mosquitoes. Three adjustable modes allow you to customize the ultrasonic signals to better repel specific pests, which is helpful for dealing with multiple types of unwanted critters.

The device plugs directly into electrical outlets and runs quietly, using very little power (3-5W), so it won’t disturb daily activities or sleep. It is safe for humans and pets since it emits no chemicals or odors. Noticeable results may take 2 to 3 weeks to appear, and for heavy infestations, multiple units might be necessary to achieve sufficient coverage, potentially increasing the overall cost.

With a compact and simple build, the repellent features a user-friendly plug-and-play design. It is well suited for people seeking a chemical-free, low-maintenance pest control solution for indoor use, especially in moderate-sized spaces.
