Reader Question:

Valentin

After the tenants, as is often the case, we were left with a bit of a mess. But in our case, the bonus is bedbugs. We began to fight three weeks ago, and immediately bought a repeller. In the market the seller advised us very much, said that such a device will protect against any house insects, and even from rats and bats. We bought it, the device did not cost much. But we were disappointed.
For three weeks we didn't go to the apartment where we connected the repellent. We thought that during this time the insects would die or at least leave the room. And so, stayed overnight for the first time, as in the morning we found the bites again. It was a complete failure. In this regard, the question about the ultrasonic repeller of bed bugs, customer reviews are real or not. After all, many write that the device helps them get rid of insects, but do not specify from which ones. Maybe it's only on the bed bugs such a device does not work. How to use them correctly, tell me.

The author of the portal answers the question:

Classification of deterrents

The range of devices in this group is constantly expanding. All modern models are divided into several main groups:

• fumigators;
• electromagnetic devices;
• ultrasonic.

The difference lies not only in the external characteristics, but also in the principle of operation. Each type of bedbug repellent performs different functions, but as a result, all devices provide a similar result - they create unacceptable conditions for the existence of different insects.

Fumigator

This group of devices includes the following types of models:

• electrical;
• aquafumigators.

They are constructed in different ways. The principle of operation of the repellent, which is plugged into a socket, is based on the release of volatile substances (insecticides). As a result, a cloud of finely dispersed suspension is formed. It is a mist that consists of such small particles that it remains invisible.

However, you can smell it (if the insecticide in the composition exhibits appropriate physical properties).

The principle of action of the aquafumigator is similar to the smoke bomb, but has a less toxic effect on people. This type of bed bug repellent is considered one of the most effective.

Electromagnetic repeller

Devices in this group help create intolerable conditions for bed bugs and other insects. The principle of action is based on the creation of electromagnetic radiation. However, its power is not high enough to scare the insects. If you change the parameters of the electromagnetic repellent, it will also make it difficult for a person to live in such a dwelling. In addition, wires and home appliances also contribute to the amplification of the electromagnetic field. But bed bugs feel good about themselves.

So, this type of device is less effective in the fight against parasites.

Ultrasonic devices

The principle of action is based on the ability to produce radiation with special parameters. It is ultrasound, it is not perceived by an adult. The main feature is the high frequency of waves (from 18 kHz and more). It is difficult for insects to stay in such conditions. They begin to look for other habitats. However, special conditions must be created for this:

• do not close the doors, which allows ultrasonic waves to propagate unhindered;
• remove soft coatings because they absorb waves;
• use an ultrasonic electrical device in accordance with its range.

What ultrasonic repellents are on the market

The main difference between the different models is the emission frequency. The best devices generate waves with parameters of 20 kHz and higher. However, there is a rule: the higher, the more effective. In addition, it is necessary to pay attention to other characteristics:

• range (determined according to the dimensions of the room where the device will be installed);
• The possibility of switching between different modes: insects are more afraid of such radiation.

Typhoon LS 500

The device is positioned as a repeller of cockroaches, fleas, ticks and fleas. The service area is 80 sq. m. The unit emits waves with a frequency of 20-50 kHz. At the same time the sound pressure level is 95 dB. This parameter determines how comfortable it will be for a person to stay in the room where the device is working.

Ultrasonic repeller of bed bugs consumes little power - no more than 4 W. It can be operated under different conditions: -15...+45°С.

Tornado Otar-2

This ultrasonic repeller is positioned as a device that helps get rid of cockroaches. However, it is also used in the fight against other by insects. The advantage of this model is considered to be the presence of the function of creating light flashes. In combination with ultrasound, it enhances the negative effects on parasites.

Device Features:

• The affected area is up to 50 sq. m;
• the possibility of changing the frequency within the range of 18-70 kHz;
• wide range of temperatures at which the device can be operated: -30°...+80°С;
• power consumption - 10 W.

Ecosniper LS 919

The device produces radiation - ultrasound from bedbugs. The manufacturer positions it as a universal means: repels rodents and insects. It is powered from the mains. The advantages of the device include minimum power consumption - 1.5 V. This will allow you to operate the repeller on an ongoing basis, without interruptions and without significant costs for utility bills.

Operating frequency of radiation: 21-25 kHz, which is considered sufficient, but there are more effective devices. Radius of action - up to 200 sq. m.

Hawk MT 04

The device operates in 3 different modes, which differ in parameters, first of all - the frequency of radiation. In addition, it is possible to switch on a mode with fixed as well as variable characteristics. Changing the modes of operation reduces the risk of addiction pests to negative factors.

Another difference of the device is the built-in plug.

WK 0600 CIX Weitech

Данная модель позиционируется производителем, как универсальная: уничтожает насекомых, мелких животных (преимущественно грызунов). Стоит намного дороже аналогов (7800.). Такой ультразвуковой отпугиватель от клопов считается профессиональным. Он обслуживает крупногабаритные объекты (площадью до 325 кв.м). Нужный результат получают благодаря наличию 2 излучателей. При этом есть возможность изменять параметры отпугивателя: предусмотрено 2 трехпозиционных переключателя.

The sound pressure is moderate - 85 dB. The ultrasound frequency varies from 1.5 to 71.5 kHz.

Pest Reject

This model device is considered one of the popular ones. The Russian version of the name - Pest Reject - is also widespread. Ultrasonic repellent against bed bugs is characterized by a high frequency of radiation - up to 60 kHz. The power source - the electric network. The weight of the device is small. The first changes in the sanitary state of the housing are noticeable in 1-3 weeks. The advantages of such a device include combined action.

The device Pest Reject is both electromagnetic and ultrasonic repellent against bed bugs.

Weitech WK-0600

The unit is large and weighs 750 g. It emits waves with a frequency ranging from 2 to 50 kHz. The power is 0.4 W. And there is a possibility to change the frequency by switching the operation modes (there are 9). The disadvantages of this device include high sound pressure - 116 dB.

Negative sensations may occur if you get closer than 1 m to the ultrasonic source. The device is connected to 220 V mains.

UP-116T

The manufacturer positions the device as effective against various insects, spiders and rodents. It is characterized by a high sound pressure - 130 dB. The repeller is connected to the mains 220 V, it has a built-in plug. The working area is 300 sq. m. The device is characterized by different capabilities: it creates ultrasonic waves, as well as produces electromagnetic radiation. The complex effect increases the efficiency. However, it is the effect of ultrasound that should be emphasized.

The area of action is large, for an apartment such a model may be too powerful (in terms of radiation strength).

Ecosniper

Various models are produced under this brand name. Among them are home devices for different purposes, destroying various pests. Most often it is necessary to remove ants and cockroaches. Such equipment has been produced for a long time, the devices have been on the market for the last 15 years. The parameters of one of them is LS 927:

Table: Comparative characteristics of the most popular bed bug repellents

In order not to buy an inefficient device, you should learn more about the capabilities of such equipment. It is recommended to pay attention first of all to the main parameters (power, frequency range, etc.), as well as auxiliary functions.

You can study the properties of each of the devices being compared independently, but the difference between them is better seen when studying the table, which immediately presents the main characteristics of popular models.

Do bedbug repellents help?

It is necessary first to understand how these parasites navigate in space. This will help to determine the most suitable means of control, and at the same time to find the disadvantages and positive qualities of repellents. So, bedwetting parasites orient in space with the help of sensitive antennae. Visual organs are not developed in all species of bed bugs.

For this reason, it is important for them to be able to smell humans (or rather, to estimate in this way the composition of exhaled air - carbon dioxide).

If this method of insect extermination is used, it is better to use it in conjunction with others.

Is it safe for people

Ultrasound is beyond the perception of an adult. And most often people do not feel such radiation and cannot hear it. However, there is a risk of exposure to the sound pressure produced by radiation. This leads to symptoms such as tinnitus and changes in hearing levels. The person does not always understand the cause of such exposure, but tends to move to another object or room.

Sound pressure increases as the radiation parameters change.

The best effect of the repellent is on mosquitoes. They use ultrasound to communicate with each other.

Transmits danger signals. Thanks to such a device, mosquitoes will not be in the room, will find another source of food. However, bed bugs do not leave the object in this case, they continue to live near the person.

Night video: an example of the ineffectiveness of the ultrasonic repeller

If such devices are used correctly, it is possible to achieve an improvement in the sanitary condition of the dwelling. To do this, it is recommended to avoid basic mistakes. For example, you can operate the repeller only on the object, the area of which corresponds to the radius of action of the device. This is due to the fact that the ultrasound will not pass through many obstacles. If you install the device in an open space without soft surfaces, the result will be noticed sooner. People do experiments: at night they observe the reaction bedbugs on the switched on device.

Where to buy scarecrows and at what price

The cost of devices may depend on a variety of factors. They also include the store policy (and markup), as well as the region. The table below shows the repellent offers of some stores.

Ask a question

- different means can be used, but the repellent from bed bugs is considered the last, because the level of its effectiveness is very difficult to maintain at the proper level - you must constantly follow the rules, which is not always possible, and the result is immediately worse;
- regardless of the model of the device, keep the doors of the room open for the entire duration of its operation;
- For low-rise buildings, it is recommended to buy more repellents, taking into account the number of floors - each floor should be equipped with such a device.

Conclusion

The repeller is designed not to kill, but to expel pests from the facility, while keeping them alive. Other features of such units:

1. Available types are: electric ultrasonic, aquafumigators and fumigators with a heating element, electromagnetic. The first two types are considered more effective against bed bugs.
2. There are many models of devices, but some work better. They include devices with a high frequency of radiation and the ability to change the parameter of this parameter. In addition, the range is taken into account.
3. In order to achieve a good result, it is necessary to keep the doors open during the operation of the device. In addition, soft surfaces (carpets, furniture) absorb ultrasound, if possible remove them.
