Does Ultrasonic Pest Repeller Work?

By Marcus Vinicius Vilkas de Aguiar

Repellers are essential accessories, especially in tropical regions that reach high temperatures and for those who live in houses close to forests. To keep you and your family safe, the market offers different repeller options.

But there is one repellent in particular that will catch your eye: the electronic repellers.

They are free of any chemical substance, do not produce waste, do not interfere with your health or that of pets and plants.

In other words, your prayers were answered!

Say goodbye to ant traps, mousetraps, poisons and mosquito nets. The use of electronic repellers dispenses with all that. And just plug it in and let it do its job.

However, many doubts arise and some internet users even express their skepticism on internet forums. So, we made this post especially to answer the question that does not want to be silenced: does the electronic repeller really work?

What is an electronic repeller?

Electronic repellers are small non-toxic devices that, by emitting UV rays or different sound frequencies, inaudible to humans, repel insects and rodents.
Electronic repellers hit the market as a novelty and alternative to chemical repellers. As they are non-toxic, they do not pose a threat to human health or to plants and pets, and can even be used in children's rooms without major concerns.

You just need to choose the one that works best in your environment!

How does electronic repellers work?

Electronic repellers can work in three ways: by attracting insects by UV rays and by electrocuting them on your electrical grid, by suction, or by repelling insects by means of sound waves. The device must be plugged into an outlet or a battery.

In other words, it is an innovative device that scares away unpleasant visitors through the emission of sound waves, free of chemical substances and residues. Or it is possible, too, to find the version that attracts insects through UV rays and electrocutes them in their electric grids and, even, suction models, without shocks.

Does electronic repellers really work?

Electronic repellers works, but success will depend on its correct use. That's because each type of electronic repeller works for a group of animal species.

Pigeons, for example, are the most difficult animals to repel with these devices, so also invest in other complementary alternatives to keep these birds away, such as specific chemical repellers for pigeons.

There are many models that can be used both indoors and outdoors.

However, in general they are designed for use in small areas (on average 50 m²). Also, ultrasound from ultrasonic electronic repellers does not penetrate walls, so they are only effective within a room.

What can be said is that, in general, the effectiveness of electronic repeller is proven. And remember to leave your repeller device active at all times.

Which electronic repeller is effective against which bugs?

Electronic repellers are effective against a number of bugs, such as rats, cockroaches, insects and ants. They can be used both indoors and outdoors.

For animals with sharper hearing, the sound wave technology of some electronic repellers is very effective.

On the other hand, there are those with less efficient hearing. Therefore, when buying your electronic repeller, take into account which animal you want to repel and choose the model that suits your needs.

What is ultrasonic electronic repeller?

The ultrasonic electronic repeller works by emitting "real" ultrasonic waves (above 20 kHz) and high sound frequencies (less than 20 kHz) capable of repelling insects and animals such as rats, ants, spiders, cockroaches and moths.

The word “ultrasonic” qualifies electronic repellers to the condition of insect and rodent repellers that act through sound waves, imperceptible to humans.

The targets of these devices can be rats, mosquitoes, ants, spiders, cockroaches, moths, etc. Everything will depend on the chosen model and the broadcast frequency.

What happens is that these ultrasonic sounds affect the animals' nervous system, disturbing them and encouraging them to leave the place, without killing them. In general, you can adjust the volume and also the intensity of the ultrasound frequencies emitted by the device.

Furthermore, the ultrasonic frequency emitted is inaudible not only to humans, but also to pets (except rodent pets such as hamsters). Not to mention that it is completely harmless to human health, being a natural and ecological option.

What is an electric repeller?

The electric repeller is that model of repeller that releases chemical substances through tablets, or in a vaporized liquid form, when connected to the electric current. This model is very efficient in fighting flies and mosquitoes.
However, the chemicals in electrical repellers can be toxic to some people, especially babies, children and pregnant women. Therefore, obey your doctor's recommendation and always read the product's package insert.

Are you looking for a good repeller to fight pests in your home?

This ultrasonic electronic repeller promises to repel rodents and some types of insects.

As its frequency mimics the sound produced by the male mosquito, the females already fertilized - the only ones that bite - move away. Bats also lose their sense of orientation because of ultrasound interference and end up abandoning their surroundings.

Likewise, larger animals leave because of the discomfort caused by the ultrasound: something useful for those who don't know how to scare away rats.

Rest assured that the ultrasound emitted does not interfere with other devices connected in the environment. Also, it doesn't bother or affect humans and pets, except hamsters.
