Say "expert in civil," recently circulated on the Internet some cell phone mosquito software, claim to emit ultrasonic mosquitoes do not like to achieve the insect repellent effect. Really work? Spring Festival period laboratories take you to explore it. Knowledge Dili The phone does not emit ultrasonic As we all know, generally identified by the human ear can hear sound frequencies not exceeding 20KHz (KHz kHz sound is the number of vibrations per second), and the sound of bats, dragonflies, male mosquitoes are issued ultrasound, wherein bat ultrasonic waves can be as high 300KHz.

Overall, ultrasonic repellent effect is minimal. Most mobile phones can not send out ultrasonic mosquito repellent software, there is no repellent effect. So, we want insect repellent or mosquito nets,http://www.e-hp.info/kawasyo-30/bbs/kawasyo-30x.cgi?res=1171, mosquito coils, water repellent is most effective.
