Most of the humans can't hear sound above 17 khZ. Our app gives you the availability to set sound frequency from 9 kHz to 23 kHz! Set frequency in way that you can't hear the sound and don't worry, mosquitos should hear the sound!

Remember: Turn your volume to max while playing sound.

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