This gadget works on the notion that, by sending out an ultrasonic sound, close to the frequency of a mosquito's wing motion, the insect will perceive the beat frequency to be a trap. Then avoids the area of the signal. The frequency characteristics of mosquitoes may vary across species and regions necessitating adjustment of the sound source. The FK918 uses a piezo transmitter to send out an ultrasonic signal which is adjustable in the 10-30KHz frequency range.
