10 HOURS Mosquito repellent sound Ultrasonic Effect (14-15)Khz | Concentration | Meditation | Sleep

It is common knowledge that mosquitoes do not like ultranoise or high frequency. Thanks to this sound repellent of (14-15)KHz sound, you will be able to repel mosquitoes and some kind of ugly flies all night long. Try it, it works. We tested this type of reppelent on New Zealand and it worked well. It is enough to make it quiet so that the human ear does not hear it, but the mosquitoes will move to the neighbors. ;-) Enjoy it.
