Repel Mice and Rats with Ultrasonic Sound
Free online ultrasonic rodent repellent with anti-habituation technology. Three target modes (mouse, rat, universal) and four sweep patterns prevent rodents from adapting to the signal. Set a session timer and let it run for hours.
How to Repel Rodents with Ultrasonic Sound
Open this page and run the speaker test to verify your device can output high-frequency sound.
Select your target pest (Mouse, Rat, or Universal) and a sweep pattern.
Set volume to maximum and choose a session duration (1-8 hours recommended).
Place the device in the room with rodent activity, speaker facing the area.
Press START SESSION and leave the device running. The anti-habituation engine varies the signal automatically.

Generate an audio file with your current settings to play on any device without internet.
For sessions longer than 2 hours, set your media player to repeat/loop mode.
Ensure your playback device can reproduce frequencies above 16 kHz.
- Pet hamsters, guinea pigs, rabbits, and other pet rodents will be affected. Remove them from the room.
- Children and young adults (under 25) may hear a high-pitched tone. Not harmful at normal volume.
- Phone/laptop speakers have limited ultrasonic output. External speakers with tweeters or Bluetooth speakers work significantly better.
- Scientific evidence for ultrasonic repellence is mixed. Use as a supplement to other pest control methods.
- Dogs and cats can hear these frequencies and may be disturbed.
This tool generates 15-22 kHz frequencies via Web Audio API. Professional ultrasonic repellers operate at 32-62 kHz at 85-100 dB SPL, which consumer speakers cannot reproduce. This provides the maximum range achievable through standard audio hardware.
