Ultrasonic Pest Chasers – Best way to repel mosquitoes

Ultrasonic pest repellers are the devices used as a substitute for avoiding inhaling toxic chemicals and fumes of mosquito killers and repellents. It is the non poisonous method of repelling pests responds to the ultrasound. Ultrasound is the highest frequency and powerful waves and is not sensitive to the human ear because a human ear can respond only in a frequency range of 20 Hz to 20 kHz. But, animals such as dogs, cats responds to 22-25 kHz, rats to 60-72 kHz and insects such as mosquitoes and flies responds to 38-44 kHz. Ultrasound can travel along a straight path when it hits an object; it bends and spread in all possible directions. Animals can produce ultrasounds as well as respond to ultrasound because they have sensory structures like tympanic membrane for detection and they also communicate each other by using ultrasound waves. Mosquitoes have sense organs to produce and receive high-frequency ultrasound waves. Spiders, wasps, beetles, flies, spiders, lizards have the capacity to detect ultrasound. These detectors are found in the antennae of mosquitoes and genitalia of cockroaches. Ultrasonic pest repellers emitted these sound waves will create pressure on the nervous system of the insects and animals and this will confuse them and finally they escape from the source of high-frequency wave device. These devices are greatly used for to repel various disease causing insects, rodents from a particular area. Ultrasonic high-frequency waves are also widely used for scanning in hospitals. Moreover, these sound waves will not pass through the walls like the sound waves. According to the literature and scientific research it is considered as safe and will not cause any damage to the human health, however, ultrasonic frequency near to 30 kHz can be detected by the kids up to a certain level, so it is advised not to use these ultrasonic chasers continuously near the children under the age of 5 years.


Response Behaviour of Animals Towards Ultrasound

  • 22-25 kHz: Dogs, Cats
  • 38-44 kHz: Mosquitoes, Fleas, House Fly, Spiders, Cockroaches
  • 52-60 kHz: Lizards
  • 60-72 kHz: Rats

Spectro Analytical Labs have fully accredited facilities for testing the various types radiations. It also provides training and assistance in this regard.

Spectro Analytical Labs Ltd. was established in the year 1995 with an objective to provide precise, accurate and reliable testing services to its customers. After having successfully completed more than 15 years in the field of providing testing and calibration services, we feel proud in sharing that during this period SPECTRO has played a pioneering role in creating for itself a globally recognized position in the field of material and analytical testing. Starting as the first lab in the country to give Direct Spectro analysis of metals (through the use of OES Spectrometers), today it has created capability to test and inspect all Engineering Materials, Building Materials, Minerals, Food & Agro Products, Rubber & Polymers, Coal, Coke & Petroleum Products and also Environmental Monitoring.
