Choosing an insect repeller

Some insects like to be close to people and parasitize. A lot of money has been invented to deal with uninvited and unwanted "guests." In recent years, an ultrasonic insect repeller has become popular. The device belongs to modern developments and excludes the use of various chemicals that adversely affect human health. Such a repeller does not exude any gases, odors, poison and acts solely on the basis of ultrasonic waves.

Operating principle

An insect repeller is a small electronic device powered by a network.

Most arthropod invertebrate insects have a very hard chitinous cover. It is their skeleton, under which are located soft tissues and organs. The strength of chitin is even superior to steel. According to physical laws, any fabric, matter has its own indicator of sound conduction.

Under the influence of ultrasound of a certain purity, the insect chitin plates begin to oscillate at such a speed that they cause pain and severe discomfort. Parasites are forced to leave the place where ultrasound exposure is felt as soon as possible.

Electromagnetic repellers act in the same way, emitting waves of a certain frequency.

The repeller does not destroy pests, but provokes them to flee from the territory. Despite the apparent primitiveness, the collective mind of insects is designed so that they remember a place where they were in danger and it is unlikely that they would ever return there.

An electronic device emitting such waves does not affect a person. People simply do not pick up such frequencies, so they don’t respond to them.

There are mobile models that you can take with you to the street. This is especially convenient for trains on the countryside or even for evening walks. After all, even in urban areas in the summer there is no end to mosquitoes and mosquitoes.

Types of electronic insect repellers

Devices for getting rid of parasites in the house are divided into 3 main types:

• electromagnetic (magnetic resonance):
• ultrasound
• combined.

Let's consider each in more detail.

Electromagnetic

When activated, the device begins to actively generate electromagnetic waves of low frequency. Electromagnetic pulses propagate over a certain range of space. The range depends on the specific model. Waves penetrate everywhere, even to the most inaccessible places.

Insects may not immediately feel the effects of the waves, so the device should work continuously for several days. After a day or two, parasites begin to feel waves that adversely affect their nervous system. The feeling of panic, fear that they feel from magnetic resonance impulses, makes them leave the room.

Electromagnetic repellers are suitable for use not only in residential premises, but also in industrial areas, in offices and other public institutions.

Ultrasonic

This type of device for repelling various types of “uninvited guests” emits ultrasonic waves. Insects begin to have very unpleasant sensations, which causes panic and flight in them.

Unlike electromagnetic waves, ultrasound does not penetrate closed doors. In multi-room premises, it is necessary to install repellers in each separate room. Furniture items, carpets also absorb ultrasonic waves, so the device is installed in such a way that its emitter is directed to the maximum free space.

Combined

Combined repellers combine immediately two types of emitters: ultrasonic and magnetic resonance. Since different waves act differently on certain insects, the combined device is able to rid the room of a larger number of pests.

You can use different types of waves either individually or by combining them with each other.

What insects does it affect

Repellers are used against a large number of insects, arthropods and even against rodents.

With their help, you can get rid of:

• cockroaches;
• mosquitoes;
• bedbugs;
• mosquito;
• ants;
• ticks;
• bees;
• wasps;
• spiders
• fleas;
• small rodents.

In addition, there are more powerful repellers from birds, bats, snakes, moles.

On sale there are universal devices that act on many types of insects and mono-devices, focused on the resonant wave range with certain types of "living creatures".

All of these types of scarers do not affect a person. But in some cases, they can affect small animals: dogs, cats, hamsters, guinea pigs. Using such a device, it is advisable to remove pets from the premises for a while.

How to choose

First you need to determine the type of repeller. It matters what kind of insects you need to get rid of. You can choose a combined universal device or model specifically for influencing a certain "living creature".

Next, you need to pay attention to the following criteria:

1. Radius of action. Each model has a characteristic marking indicating the maximum distance of the propagated waves. The higher this indicator, the greater the area covered by the repeller.
2. Food. Most devices are powered by the network, but there are also battery powered ones. When buying a stand-alone device, keep in mind that batteries are not always included. There are combined devices, they may be the best choice.
3. Power. Wave radiation has a certain range of power, depending on the generators. A device generating weak waves will act slowly and ineffectively.
4. Environmental requirements. Some models work only within a certain temperature. They will not function in cold or extreme heat. This indicator matters if the repeller is selected for non-residential premises.
5. Dimensions Almost all insect repellers are small. If the device is powerful and has several generators, it can be larger.
6. Indicators. Light sensors will indicate which mode the device is in. This is an important criterion that allows you to see whether the device is working or not, because it does not produce other visual or sound signs.
7. Body. Usually repellers have plastic cases. Less common are models in a metal case. Pay attention to the quality of the plastic. A thin body may burst if struck or dropped.
