Mice and rats have a much broader hearing range than humans, extending well into the ultrasonic spectrum (up to 70–90 kHz).
Sound waves at these frequencies do not travel through walls or furniture. For the best results, place the speakers in the open, directed toward the area where activity is highest.
This 11.5-hour audio track is designed as a high-intensity acoustic deterrent for rodent control. By utilizing specific frequencies—15,000Hz, 17,500Hz, and 20,000Hz—it targets the sensitive auditory range of mice and rats to encourage them to vacate a space without the use of traps or chemicals. How it Works Mice and rats have a much broader hearing
These frequencies transition into the ultrasonic range. To a rodent, these sounds are akin to a loud, relentless siren. Because rodents use sound for communication and predator detection, this "acoustic stress" makes the environment feel unsafe and uncomfortable. The Benefit of 11.5 Hours
The volume needs to be high enough to fill the room, but be mindful of pets. Dogs and cats can hear these frequencies and may become stressed. This 11
This is at the edge of human hearing (often audible to children and young adults as a high-pitched whine) but is piercingly loud to rodents.
The extended duration is the most critical feature. Short bursts of sound are rarely effective because rodents are adaptable; they will simply hide until the noise stops. An 11.5-hour loop covers the entire duration of their peak nocturnal activity. By maintaining constant pressure through the night, the audio disrupts their ability to forage, communicate, and nest, eventually forcing them to seek a quieter habitat. Best Practices for Use To a rodent, these sounds are akin to
Use this audio in conjunction with physical barriers. While the sound drives them out, sealing entry points with steel wool or caulk ensures they can't return once the audio is turned off.
