Mosquito repellent

New variable sonic emission technology (3 sound levels) for greater repellent effectiveness. Practical with indicator light and on / off button. Without chemicals, odors and refills. Safe for children, pregnant women, allergy sufferers / asthmatics and pets. For internal use and public places, it protects up to 60-80 m3. Works with 230 V 50 Hz 0.3 W electrical outlet. Sonic emissions are low frequency sounds, usually slightly audible to the human ear but very annoying to some insects including mosquitoes. The anti-mosquito sonic emissions reproduce the sound of the male`s wings by driving away the female mosquitoes, the ones that "sting", in search of the blood necessary for the reproduction and development of the eggs. To ensure better repellent efficacy and avoid the addiction of mosquitoes, a new technology has been developed with variable sonic emissions with modulated frequencies and intensities. The sonic waves radiate into the area starting from a source point and propagating in a circular fashion. Sonic waves attenuate with distance. The variable sonic waves, at the right frequency and with the correct waveform, guarantee an excellent repellent effect especially for mosquitoes. Being slightly audible, it is possible to vary the intensity up to 3 levels according to your liking. If used in a home environment, especially in the bedroom, it is recommended to set the device to maximum intensity before going to bed and to minimum once in bed.
