"Anti Housefly Killer Sound Prank" is a prank app and will help you to keep all Houseflyes away from your house! This app emits different high frequency sounds (ultrasonic sounds) which should irritate all small insects and Houseflies in your home. Houseflies might perceive that sound as the sound of their enemies and get irritated. 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 Housefly 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.
!!!!! PLEASE READ !!!!!!!!!!!!!! Please take this app as a prank only. This app is not a real Housefly killer tool! The description above is only conjectures!
