Ultrasonic mosquito repeller: how effective is it?

With the onset of a warm season, many are faced with the problem of mosquitoes, which not only annoy their intrusiveness, but can pose a high danger to health. Among a variety of means and devices from insects, the ultrasonic mosquito repeller provokes increased interest. What is this device different from traditional and customary for us sprays, fumigators and mosquito nets?

Principle of operation

Many things are known about the effect of ultrasonic waves on living organisms. Therefore, ultrasonic devices are actively used to repel dogs, rodents and, of course, mosquitoes. The general principle of the operation of such devices is based on the fact that ultrasound acts on the nervous system of animals and insects, thereby greatly frightening them. The human ear does not catch the sound generated by the household appliance.

Now let's talk specifically about repelling mosquitoes. It is important to understand that only females bite a person who need nutrition for bearing offspring. The ultrasonic repeller emits signals that coincide with the sound that male mosquitoes produce to attract female individuals for the purpose of fertilization. If the female is already fertilized, then the summoning peep of the male scares her, so she tries to leave this place as quickly as possible.

That's why a repeller installed at home or on the street, creates a mosquito-free zone. At purchase it is necessary to consider the area on which the device is designed. Usually the action of portable devices extends to a distance of up to 2 m, and stationary - up to 5 m. In addition, the efficiency of the repeller can be affected by other factors: terrain, time of day, weather conditions.

Today there are more than 3000 species of mosquitoes, and in Russia there are about 100 species. For mosquitoes that live in a certain area, its own frequency is inherent. That is why a repeller effective at one point in the country can be absolutely useless in another. But progress does not stand still, and some modern models with adjustable frequency of ultrasonic waves are effective practically on any territory. Such universal devices operate at frequencies from 14 to 20.5 kHz.

Ultrasound, in contrast to some other means, does not kill mosquitoes, but only scares them away and disperses them from the area. But not always it is necessary to hope for a cumulative effect. After turning off the scarer, it stops working, so mosquitoes can return.

On the Internet you can find many instructions and schemes for self-assembly of the repeller. But without special knowledge and skills it is difficult to calculate, the sound of what frequency and power will be safe for people. And the device, made by own hands, can cause headaches.

How and where to install the ultrasonic repeller?

Using a portable repeller does not cause any problems. It only needs to be turned on and secured to the arm, belt or clothing. And how to install a stationary ultrasonic mosquito repeller to make its effect more effective?

That is, there should be no barriers between the device and your bed. Well, if there is at least 2-2.5 meters of free space in front of the radiator.

Be prepared for the fact that for more effective protection in the apartment there will be a need to install not one but two or more devices. If the repeller is placed in one room, and doors are open to other rooms, ultrasound may spread to these rooms. But this is provided that the device has sufficient power.

Ultrasonic repeller will be effective on the street, but it is necessary to take into account one nuance. In the room, ultrasonic waves are reflected from the walls. And in the open space, for example, in the suburban area, they spread to the sides without any obstacles, so the effectiveness of the product on the street is reduced. This means that to protect an identical in size territory on an open site it is better to purchase a device of higher power than for home use.

The modern market offers a wide choice of models - from the most simple and inexpensive to devices equipped with a mass of additional functions. But for an ultrasonic repeller to really help you fix the problem, it is recommended to study its technical characteristics and operating rules before buying and using it.
