"Anti Mouse Repellent Sound Prank" is a prank app and will help you to keep all Mice and bugs away from your home!
This app emits different high frequency sounds (ultrasonic sounds) which should irritate Mice.
Mice might perceive that sound as the sound of their enemies and should get irritate.
Just select the amount of sound you want and keep your mobile phone near you.

Humans cannot hear sound above 17 KHz properly.
This app gives you the option to select sounds from 9 kHz to 22 KHz!
Select the frequency of your desire and test in your home. Select the optimum frequency and repeal those insects.

Remember: Turn your volume to max while playing sound.

This app does not guarantee 100% chance of success. There are a lot of Mouse species in the world and some of them may be resistant to ultrasonic sounds. Moreover some built-in phone speakers are not able to produce high frequency sounds.
