What you need to know about ultrasonic mosquito repellers?

With the onset of the warm season, many are faced with the problem of mosquitoes, which not only annoy with their importunity, but can also pose a high risk to health. Among a variety of insect repellents and devices, the ultrasonic mosquito repeller is of great interest. How does this device differ from the traditional and familiar sprays, fumigators and mosquito nets?

Operating principle

A lot is known about the effect of ultrasonic waves on living organisms. Therefore, ultrasonic devices are actively used to scare away dogs, rodents and, of course, mosquitoes. The general principle of operation of such devices is based on the fact that ultrasound acts on the nervous system of animals and insects, thereby greatly scaring them. The human ear does not pick up the sound generated by the appliance.

Now let's talk specifically about repelling mosquitoes. It is important to understand that only females who need food to carry offspring bite a person. An ultrasonic repeller emits signals matching the sound that the male mosquitoes emit to attract females for the purpose of fertilization. If the female is already fertilized, then the male’s draft squeak scares her, so she tries to leave this place as soon as possible.

That is why a repeller installed at home or on the street creates a mosquito-free zone. When buying, it is worth considering the area for which the device is designed. Typically, the effect of portable devices extends to a distance of 2 m, and stationary - up to 5 m. In addition, other factors can affect the effectiveness of the repeller: terrain, time of day, weather conditions.

Tip

The action of such devices is aimed specifically at biting females. If you want to completely get rid of absolutely all mosquitoes, and not just bloodsucking, then an ultrasonic repeller will not work for you.

Types of repellers

• Standalone. These are portable battery-powered repellers that you can always carry with you, for example, while hiking, walking in the fresh air or playing sports. In appearance, the portable repeller is similar to a standard keychain. It can be mounted on the outside of the garment, belt, or even on the pet’s collar. There are also repellers in the form of bracelets. The continuous operation time of portable repellers is about 3 days.
• Stationary devices work from the outlet. Usually they are used for rooms. There are also summer and beach options. Some devices are equipped with photosensors that automatically turn on when dark.
• Multifunctional. Many modern models have more features. For example, there are repellers that can work both on batteries and on mains. You can find models equipped with additional options. It can be a purifier, an air ionizer, a flashlight or a built-in compass

Worth knowing

Almost all ultrasonic mosquito repellers also repel mosquitoes. But for the fight against cockroaches, bugs and ants such a device is no longer suitable.

Benefits of Ultrasonic Repellers

1. The repeller is absolutely safe for people and pets. A person does not hear ultrasonic waves generated by the device, they do not affect the psyche and nervous system. Therefore, you will not experience any discomfort during use.
2. The absence of toxic chemicals and unpleasant odors that are often encountered when using sprays, fumigants, candles, etc.
3. Mosquitoes do not get used to ultrasound. Therefore, you do not have to worry that after a couple of months of use, they will cease to be afraid of it, and the operation of the device will end.
4. The included device does not affect the operation of various equipment: televisions, telephones, radios.
5. A high-quality ultrasonic mosquito repeller will last you for many years. Stationary appliances do not require additional costs: tablets, liquid for refueling, etc.

What else do you need to know about repellers?

Today, there are more than 3,000 species of mosquitoes, and about 100 species live in Russia. For mosquitoes that live in a particular area, its own frequency is inherent. That is why a repeller that is effective at one point in the country can be completely useless at another. But progress does not stand still, and some modern models with adjustable frequency of the ultrasonic wave are effective in almost any territory. Such universal devices operate at frequencies from 14 to 20.5 kHz.

Ultrasound, unlike some other means, does not kill mosquitoes, it only scares them away and disperses them from this territory. But it is far from always worth hoping for a cumulative effect. After turning off the repeller, it stops working, so mosquitoes can return.

Tip

On the Internet you can find many instructions and diagrams 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 a do-it-yourself device can cause headaches. Therefore, it is better to purchase mosquito repellers created by professionals.

How and where to install an ultrasonic repeller?

Using a portable repeller does not raise questions. It only needs to be turned on and secured to a hand, belt or clothing. But how to install a stationary ultrasonic mosquito repeller, so that its action is more effective? To properly position the device, you need to know that ultrasonic waves do not pass through walls, partitions and other obstacles. Therefore, when installing the device, it is necessary to take into account not only the overall size of the room, but also its geometry, the presence of furniture, partitions and other possible obstacles.

Determine which areas you want to protect in the first place, such as a bed or dining table. The repeller should be positioned so that the ultrasound easily reaches this place. That is, there should not be any obstacles between the device and your bed. It is good if at least 2-2.5 meters of free space remains in front of the emitter.

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 located in one room, and the doors are open in other rooms, ultrasound can also spread to these rooms. But this is provided that the device has sufficient power.

An ultrasonic repeller will be effective on the street, but one nuance must be taken into account. In the room, ultrasonic waves bounce off the walls. And in open space, for example, in a summer cottage, they spread to the sides without any obstacles, therefore, the effectiveness of the product on the street is reduced. This means that to protect a territory of identical size in an open area, it is better to purchase a device of a higher power than for home use.

Ultrasonic repeller is an excellent protection against blood-sucking insects. The modern market offers a wide selection of models - from the simplest and cheapest to instruments equipped with a host of additional features.But so that the ultrasonic repeller really helps you fix the problem, it is recommended that you study its technical specifications and operating rules before buying and using.
