New apps for smartphones are now available in Google play store that can keep mosquitoes away. Either you may get “Mosquito Repellent” or “Anti Mosquito“. both the apps repel mosquitoes by generating high frequency sounds, The frequency is such that Mosquitoes are irritated of it.
How the app works?
The app simply emits frequencies from 9kHz to 22kHz, you just have to set a frequency that you can’t hear. Obviously it would be more than 20kHz, As humans can hear sounds ranging 20Hz to 20kHz. However Depending on the particular app, the sound is probably right at the edge of human hearing, so children or those with excellent ears might even be able to hear it, although adults might not.
Once you tap on the “Mosquito icon”, the app plays the ultrasound (that can’t be heard by the human ear) that simulates the sexual recall of the male mosquito, causing repulsion to the already fertilized female mosquitoes, the only which are able to bite. The idea sounds reasonable.
However Ultrasonic repellants that claim to work on the same principal have been around for decades. Before smart phone apps, the sound was emitted from plug-in or battery-powered electronic devices. Those are still on the market too.
How to use?
you always can keep smartphone that makes its use even in offices, bus, train and everywhere you want. Now you don’t have to carry all other repellents along with you every time.
'Thus there is no evidence that these EMRs could potentially be useful in preventing malaria in humans.’
There is also said to be little evidence female mosquitoes avoid males after they’ve mated.
The Liverpool researchers added that ‘male mosquitoes are actually the ones attracted by the female flight sound, and females normally have a very weak sensitivity for sound compared with the males.’
Wayne Crans, Associate Research Professor in Entomology at Rutgers added mosquitoes are also not know to leave areas hunted by dragonflies.
Reviews of the app additionally state that the sound is audible and ‘annoying’.
The muggy weather is creating a ‘perfect storm’ for mosquitoes to descend on our gardens.
But the latest high-tech weapon in the battle against the bloodsuckers doesn’t come in the form or a spray or clip, instead it’s a free app on your smartphone.
Anti-mosquito apps emit ultrasonic frequencies designed to frighten the mosquitoes away.
They do this by either mimicking the sounds of mosquito predators, such as dragonflies and bats, or by using the sound made by the wings of male insects.
Once a female mosquito has mated, she is said to actively avoid contact with males, so by playing this sound, the females stay away.
The most popular app is called the Anti Mosquito Sonic Repeller.
Its developers claim that the pitch of the sound it produces is so high, most humans don’t notice it.
It also comes with various frequencies in order to target different mosquito species within specific locations.
Although, the app does not guarantee 100 per cent protection, because ‘there are more than 3,500 known mosquito species in the world and they all react slightly different to the repellent’.
Other apps that play ‘mosquito sounds’ are designed to annoy people, rather than repel mosquitoes but have been found to serve that purpose by accident.
