10 Best Ultrasonic Bat Repellers 2025 in the United States

The Cleanrth CB006 Advanced Ultrasonic Bat Repelling System stands out in the ultrasonic bat repeller category primarily due to its innovative Batonic feature. This technology utilizes two speakers to create dynamic sound channels that aim to effectively repel bats without harming them. This makes it a solid choice for those looking for a humane solution. The device is designed with a significant coverage area of up to 7,000 square feet, making it suitable for both small yards and larger open spaces. It is also weather-resistant, allowing for outdoor use without concern about the elements.

One of the most appealing aspects of the CB006 is its safety for pets and humans, which is a critical factor for many users. The absence of harmful chemicals means you can use it around household pets without worry. In addition to Batonic, the unit includes features like inner-wall electromagnetic repulsion and Bat Targeting, providing a comprehensive approach to bat control.

There are a few considerations to keep in mind. Some users may find that ultrasonic repellents vary in effectiveness, depending on the specific bat species and environmental conditions. Additionally, while the comprehensive customer support is a plus, some users might wish for more detailed guidance on optimal placement and usage to enhance effectiveness.

The CLEANRTH BCS202 Bat-Blocker Pro uses ultrasonic sound waves to keep bats away, making it a humane option for homeowners aiming to prevent bat infestations. It features a tri-sonic system with three speakers arranged to create a surround sound effect, effectively covering an area up to 5,000 square feet, which is suitable for open spaces like backyards or patios.

With three ultrasonic modes, the device helps prevent bats from becoming accustomed to the sound, enhancing its effectiveness over time. Setup is simple with a 6-foot plug-in cord, allowing for immediate use. It is safe for humans and pets, making it appropriate for families and homes with animals.

The device requires a nearby power source due to its plug-in design, which could limit placement options. This repeller is a good choice for those seeking a non-lethal method to deter bats in medium to large outdoor areas, though users should consider placement carefully.

The BugWomp-BEU Bat Expulsion Unit is a plug-in ultrasonic bat repellent designed to cover up to 7,000 square feet, making it suitable for large indoor areas like basements or attics where bats might nest. It uses dynamic ultrasonic sounds along with electromagnetic pulses sent through your home's wiring, which can help deter bats inside walls—a useful feature not common in all ultrasonic repellers. The device is easy to set up with simple slider switches and recommended settings, so you can start using it quickly without technical hassle. It comes in a compact black plastic design and weighs just under 5 ounces, so it won’t be intrusive.

This repellent is intended primarily for indoor use since it lacks specific weather resistance, making it unsuitable for outdoor spaces exposed to rain or harsh conditions. The product includes helpful guides on bat coverage and offers a support program if bats persist, enhancing its user-friendliness. With a moderate customer rating and a modest price point, it serves as a practical choice for homeowners seeking a non-chemical, humane method to keep bats away from indoor living spaces.

It is important to note that multiple units may be needed for very large or complex areas, and the device does not provide physical barriers or traps. Therefore, it is best used as part of a broader bat control strategy.
