In fact dragonflies have a wing beat frequency of between 20 and 170Hz - a much lower frequency than 15kHz. But Bart Knols says this lower frequency is equally useless at driving mosquitoes away or stopping them biting. Insects like Mosquitoes, Flies responds to 38-44 kHz. US are widely used in Homes, Gardens, Farm yards etc. to repel various kinds of pests. Commercial US are designed to emit US in the frequency range 20 kHz to 100 kHz. US above 20 kHz is inaudible to man but children can hear the US to a certain level up to 30 kHz. 388 min - Uploaded by Milleaccendini7 Day 168 HRS Anti mosquito Sound https://www.youtube.com/playlist?list. Wouldn't it be the coolest thing ever if you could download an app to your cell phone that would turn your phone into a safe, free mosquito-repelling machine?.. but the claims still tend to be general ones, with cautions such as the devices won't work for all mosquitoes, or you need to experiment to find the right frequency. In 2012, a radio station in Sao Paulo, Brazil, started transmitting, along with its regular music broadcast, an audio signal at a frequency not audible to the human ear. The station told its listeners to stay close to the radio during the broadcast because the hidden, underlying tone repelled mosquitoes. Recent reports of more cases popping up can be concerning enough that you might reach for technology—and in the iTunes App Store, you'll find a gazillion apps that promise to repel the little disease-carrying beggars with high-frequency sound. Unfortunately, they don't work. Based on my experience on. Some smartphone applications attempt to use this technology to produce high frequency sounds to repel mosquitoes and other insects, but the claims of effectiveness of these application and of ultrasonic control of mosquitoes in general has been questioned.

The US sensors are present in the antennae of Mosquitoes and genetalia of Cockroaches. US emitted by the Repeller will scare away the pests and confuse them. Ultrasonic sound will create stress on the nervous system of insects and jam their own US frequency. This will immobilize the insects and they escape from the. Dragonflies are the mortal enemy for mosquitoes and in flight they generate sound frequencies (approximately) between 67 Hz and 45 Hz, depending on their sizes. 56 Hz is a good average number in between those frequencies.
