Ultrasonic devices (sonic mosquito repellent) operate by emitting short wavelength, high frequency sound waves too high in pitch to be heard by the human ear (mosquito sound). This is due to limitations in human hearing. Humans can not hear ultrasound (mosquito sound) because the eardrum does not vibrate fast enough, but some animals such as dogs, bats and rodents can hear well into the ultrasonic range. Some insects, such as grasshoppers and locusts can detect frequencies from 50,000 Hz to 100,000 Hz, and moths and lacewings can detect ultrasound as high as 240,000 Hz produced by insect-hunting bats.
Insects detect sound by special hairs or sensilla located on the antennae (mosquitoes) or genitalia (cockroaches), or by more complicated tympanal organs (grasshoppers, locusts, moths and butterflies).
Electronic pest (mosquito repellent) control is the name given to the use of any of the several types of electrically powered devices designed to repel or eliminate pests, usually rodents or insects.
Numerous electronic pest control devices (mosquito repellant) are readily available throughout the world. Hardware stores and garden centers usually stock some sort of electronic device advertised to repel a variety of pests and one can also find them on the internet. Although these devices (mosquito ringtones) have been around for at least 20 years, they have only recently become popular and widely advertised, probably due to their environmentally friendly claims.
