Response of Animals to Ultrasound
22-25 kHz: Dogs, Cats
38-44 kHz: Mosquitoes, Fleas, House Fly, Spiders, Cockroaches
52-60 kHz: Lizards
60-72 kHz: Rats
How does ultrasound repel pests?
US pest chasers are designed to repel pests from the home. Rodents respond to US with a frequency around 60 kHz. Cats and Dogs can be repelled using 22-25 kHz. Insects like mosquitoes, House fly, Fleas etc responds to 38-44 kHz. US will create high pressure on the eardrum of Rats so that they move away from US source. US generally creates stress on animals, so they avoid ultrasound.
How does Ultrasound repel Mosquitoes?
Male mosquito is the natural enemy of female mosquito after breeding. Both male and female mosquitoes use plant juice as food. But female mosquito requires human blood protein for the maturation of their eggs. Male mosquitoes will not bite human beings. On the first day of emergence, the female mosquito will not bite but after mating with male it starts to bite human beings to get blood. Female mosquito will not allow males to mate again and they avoid the presence of males. Females detect the presence of males by sensing the US produced by the males. If an US generator is used, it will imitate male mosquito by producing 38 kHz US . This will repel Female mosquitoes. Moreover the US will create stress on the US sensillae present on the antenna of female mosquitoes, so the move away from the source of US .
