How does electronic mosquito repellent work

Mosquitoes respond to ultrasound. The ultrasound affects the nervous system of the mosquito, so they tend to avoid signals.

Electronic mosquito repellent works by emitting ultrasonic sound.

Most of the manufacturers claim the device work by imitating the sonar signal of bats and the ultrasonic sound of a male mosquito. The bat emits ultrasonic sound waves which they use to locate mosquito they eat so when the mosquito hears the sound will leave the area to avoid being eaten.

The male mosquito also produces ultrasonic flight sounds which female mosquito avoid after they have mated.

So the electronic mosquito repellent is made to mimic bats ultrasonic sound waves and male mosquito ultrasonic flight sound to repel the mosquitoes.

Ultrasonic sound drives the pest away without killing them so no need to clean up dead pests.

Ultrasonic sound is environmentally friendly because you do not use the chemical to drive away pests and rodents.

Does electronic mosquito repellent work

According to research done by scientists mosquito respond to ultrasound from 35-60KHZ frequency range.

So if we start with a smartphone app, they produce a frequency of 15KHZ. So the ultrasound produced is below the one mosquito can respond to making the app ineffective.

Manufacturers of Ultrasonic mosquito repellent claims the device is capable of generating a frequency from 20KHZ to 100KHZ. But research done by scientist claims the device is not effective unless combined with other technology or the sound pattern is regularly changed.

The technology includes adding a repellent mat, which we will discuss below.

The other technology which can help the device attain the desired result is using ultrasonic mosquito repellent that produces a frequency of above 35KHZ with built-in conditioner circulating cool air or fan.

Using ultrasonic devices and fans when both are switched on is more effective in killing and repelling mosquitoes.

Using both ultrasonic devices with the built-in fan is effective in killing and repelling mosquito.

The Electronic mosquito repellent fitted with repellent mat inside are effective. The repellent mat is activated by heating elements releasing pesticides, which is capable of repelling and killing a mosquito.

They have proven to be effective among all mosquito repellent.

According to the research done by science daily, Wearable electronic mosquito repellent are not effective unless it has a built-in fan circulating metofluthrin, which is effective in killing and repelling mosquito.

How do fan repel mosquito

Mosquitoes are weaker flyers by nature they prefer flying when the wind is calm or still. Mosquitoes do not fly when the wind speed is greater than 7MPH.

Mosquitoes and other flying insect desist from flying near windy areas. Back to fan since the fan produce that wind current this make a good reason they succeed to repel mosquito.

Another reason mosquito-like moist areas. When the fan moves it keeps the area drier and less humid/moist therefore not attractive to mosquitoes.

The third reason fan disperses carbon dioxide we breathe out and other chemicals (like sweat) our body expel that attract mosquito. So it becomes hard for the mosquito to locate the carbon dioxide source or sweat source.

The Electronic mosquito repellent fitted with repellent mat inside are effective. The repellent mat is activated by heating elements releasing pesticides, which is capable of repelling and killing a mosquito.

They have proven to be effective among all mosquito repellent.

What to consider when buying the electronic mosquito repellent

  • Frequency

Mosquito responds to ultrasound between 35 to 60 kHz frequency ranges.

When buying ultrasonic mosquito repellent make sure it produces frequency above 35KHZ for it to be effective in repelling mosquito.

So the higher the frequency, the more mosquitoes are repelled.

  • Power source

Mosquito repellent uses different types of the power sources. Some are electric-powered, rechargeable battery-powered, solar-powered and other use gas like Thermacell Backpacker Mosquito Repeller 

When choosing the repellent, make sure you chose the one that suits the power available in your area.

  • Range

Mosquito repellent is effective or covers a specific area. Make sure the device you buy is covering the right area.


When buying mosquito repellent make sure it generates high frequency from 35KHZ and above to repel the mosquito effectively.

Although the device alone is not effective for better results use the ultrasonic device together with a fan.

So according to the review above the electronic mosquito repellent that has a repellent mat is the most effective method to repel mosquitoes.

Also, the ultrasonic device with a built-in fan is another effective electronic mosquito repellent.

Hoping our article is useful and will guide you to choose the right electronic mosquito repellent.
