The principle of operation of ultrasonic repellers and reviews

The bedbug repeller is the latest invention that allows you to get rid of parasites without much effort. A small device operates on the basis of ultrasound and electromagnetic waves. Prolonged exposure of insects to the repeller leads to disruption of the nervous system. Parasites voluntarily leave the premises.

What ultrasonic repellers are on the market?

Currently, the market is simply overflowing with insect repellers of domestic and foreign production. Chinese ones are in great demand for obvious reasons - low price. The device itself is a small box with several lights and buttons. Most of them have the ability to change modes. The prices for ultrasonic repellers vary. There are cheap products of economy class, mid-price category, and expensive ones. According to the principle of operation, they are practically no different. The whole difference is in the diameter of the impact, the reliability of the mechanism itself. Cheap repellers use a conventional sound sensor. Mid-range devices use ultrasound with a relatively small impact diameter. In order for insects to experience discomfort, it is necessary to install several devices in one room in different corners. Expensive repellers have a similar mechanism of action, but a large radius of ultrasound; high-quality materials are used for manufacturing.

The repeller runs on batteries or is connected to a power source using an outlet. Since long-term continuous operation of repellers is required, you should pay attention to the quality of the device itself and the materials from which it is made. Otherwise, the trendy repeller will simply melt.

Types of repellers

Nowadays it is difficult to keep track of the names of insect repellers, but the following brands are especially popular:

• Typhoon is a representative of domestic products. It looks like a Soviet radio. The weight of the device is 200 grams. Works exclusively from the network. It is possible to switch the sound mode, which prevents insects from becoming accustomed to ultrasound of a certain frequency. The device costs around 1100 rubles.
• Banzai is a Chinese product that does not stand out in any way. A small white box for all types of insects at once. In this case, only 2 modes are switched. A menacing looking samurai with a sword. Judging by customer reviews, bedbugs are not afraid of sound or sword. Battery operated. The cost of the repeller is about 100 rubles. Repellers made in Russia are produced under the same brand name. How they differ is not particularly clear, but the cost of one device is already around 1,500 rubles. Impact radius 25 sq. m. Powered by network.
• Tornado is again a domestic product designed to combat rodents. A powerful drug whose waves can overcome obstacles. The action extends to the entire room and neighboring ones.

• EMR-21 is a Bulgarian-made device. Powered by network. It is an inconspicuous white box with a screen and several buttons for switching modes. In addition to ultrasound, it creates an electromagnetic field, which increases the effectiveness of the device in the fight against bedbugs. After connecting, resonant small vibrations arise in the electrical network wiring, they are transmitted to the walls, affect the condition of the insects, and force them to leave the shelter. The cost of the repeller is around 1100 rubles.
• Ecosniper - produced in Russia. More like a mine. Round in shape, grayish in color, with flashing lights. Designed to repel rodents, birds and insects. Can be used outdoors and indoors. The cost of the device is about 1300 rubles.
• Pest Reject is a drug on which special hopes are placed. The action begins immediately after connecting to the outlet. In addition to ultrasonic waves, it creates an electromagnetic field that is unfavorable for insects. Impact radius up to 200 sq. m. There is no need to buy 2 devices. One repeller will cope with living creatures on its own. The cost of Pest Reject is within 2000 rubles, which makes it especially popular. The device is actively sold via the Internet.

Review of popular models

Ultrasonic and electromagnetic devices are recommended for use in premises for various purposes, including kitchens, bedrooms and storerooms.

Typhoon LS-500

The ultrasonic repeller Typhoon LS-500 will cope not only with bedbugs, but also with cockroaches, covering an area of ​​up to 80 m2. The operating principle of the Typhoon repeller is based on the operation of a special microcircuit that constantly changes the frequency and duration of ultrasonic pulses, which guarantees that insects will not adapt to them.

Ultrasound does not pass through walls, thick fabric, doors or other obstructions, so you will most likely need to use one device for each room. The required effect, according to the developers, is achieved in the second to fourth week from the moment the gadget is turned on.

Tornado OTAR-2

The universal device Tornado OTAR-2 repels not only bedbugs, but also cockroaches, fleas, ants and spiders. This ultrasonic device is easy to use and provides additional light exposure to insects.

The best result is achieved when installing the device in an open space and at a height of one to one and a half meters above the floor. A slight deviation of the repeller relative to the vertical axis is acceptable. The room should be treated again after a week.

EcoSniper LS-919

A universal ultrasonic device that works against bedbugs and other insects. LS-919 will help get rid of pests by treating the room with powerful pulses of ultra-high frequency sound waves, which provoke stress and panic attacks in parasites. As a result, bedbugs move away from the device’s coverage area.

EcoSniper LS-919 operates from a standard electrical network. The maximum effect is achieved after two to five weeks of constant operation of the device. When installing the gadget, you should take into account that carpets, walls and upholstered furniture prevent the propagation of ultrasound.

Hawk MT-04

The manufacturer emphasizes that the Hawk covers an area of ​​up to 150 m2 and can operate in one of three modes. The first is the most effective fixed-frequency mode, but with the risk of insects becoming accustomed to the radiation. The second is the effect of rapid frequency conversion, which does not cause adaptation in bedbugs. The third mode is a slow frequency conversion with no addiction and a long-lasting effect.

Hawk MT-04 can be used in premises for various purposes.

WK 0600 CIX Weitech

The ultrasonic repeller WK 0600 CIX Weitech is a rare device in terms of parameters such as price and quality, which can be classified as professional. This statement is based on the carefully thought-out design of the device, high-quality components and the impressive power of the gadget.

WK 0600 CIX Weitech contains two sensors, which gives a wider radiation pattern, and can operate in nine modes, which allows you to select the most optimal level of impact on pests. For the first two weeks, continuous operation of the device is recommended. After this, the emitter is turned on at night for preventive purposes.

Pest Reject

The Pest Reject bedbug repeller operates in ultrasound and magnetic resonance radiation modes, which leads to nervous exhaustion of insects and forces them to leave the coverage area of ​​the device.

Pest Reject is positioned by manufacturers and dealers as an ultra-compact, but powerful and versatile means of pest control, including bedbugs. The brand has been successfully advertised, and the low cost of the gadget attracts buyers like a magnet. However, it is worth considering that the manufacturer can supply only the cheapest components to a device costing 400–500 rubles, and this fact alone causes conflicting opinions. Reviews from the majority of consumers of this repeller only increase doubts about its effectiveness.

Set the required mode and leave it on until the bedbugs disappear. It is recommended to turn it off periodically to avoid damage. It is necessary to use the device for a long time. Only at the end of the month can you notice a visible result. In addition, you should pay attention to the radius of influence of the repeller. You may have to install several pieces in one room at once.

Instructions for use:

• remove from packaging;
• plug into the socket;
• set mode.

To prevent insects from becoming accustomed to constant ultrasound. Modes should be changed periodically.

Do bedbug repellers help?

People like to discuss the effect of fashionable, convenient products against bed bugs on forums. You may find conflicting reviews. At the same time, it is difficult for an ignorant person to figure out whether it works on bedbugs or not. To understand whether a repeller is useful, you need to pay attention to some nuances:

• There is not a single device that says “from bed bugs” in black and white. The pictures show rodents, cockroaches, fleas, and mosquitoes. The purpose is the same. And the fact that ultrasonic and electromagnetic repellers work on bed bugs, including since they are also insects, was decided by the buyers themselves. Sellers simply support their desire to quickly get rid of parasites in the house in various ways. It is recommended to use the repeller in conjunction with other bedbug repellents. So should you buy it at all?
• Initially, repellers were released to combat mosquitoes and showed high efficiency. Many manufacturers played on this, expanded the range of action of the device, and added other insects and rodents.
• In the case of mosquitoes, everything is clear. They are guided by ultrasound. They give signals to their relatives of different frequencies, which are not noticed by humans. A device with ultrasonic waves interferes with their communication. They cannot transmit a reliable signal to each other, and they themselves do not orient themselves in space. They try to leave the room as quickly as possible. When it comes to bed bugs, their way of life is significantly different. Bedbugs are guided by their sense of smell and do not notice any sounds, even ultra-sounds. Therefore, an ultrasonic bedbug repeller is an absolutely useless thing.
• Moreover, no one will buy an expensive device to combat bedbugs. Namely, he has the ability to send waves through the wall. Such ultrasound can overcome an obstacle. Cheap repellers only work in the room itself. They cannot reach the bedbugs that are in the outlet, under the mattress. In watches and so on. And they can settle in a variety of places.
• The action must be continuous. But no device can withstand constant switching on for several months. Periodically turning off the repeller allows bedbugs to continue their normal activities.
• Each repeller has only 2-3 ultrasonic modes. And manufacturers claim that they act on both rodents and insects. Moreover, each living creature requires its own ultrasound range. Then another question arises: where is the guarantee that they do not negatively affect the nervous system of domestic animals and humans?

Bed bugs are the most invulnerable creatures. Some victims have the impression that they are immortal. Ultrasonic repellers promoted by advertising give hope for speedy relief to all those who do not want to do anything special or have been pointlessly struggling with them for several months. Reviews of effectiveness are either false or addressed to mosquitoes, cockroaches, and fleas. Moreover, manufacturers indicate that insects are gradually “going crazy.” While a person waits a month for the result, the colony of bedbugs will increase significantly. The repeller definitely has no effect on embryos in eggs. Wasted time, severe contamination, wasted money. All these are consequences of fighting bed bugs using a repeller.

Dangerous or not for humans

The increased power of ultrasonic and electromagnetic repellers has a negative effect not only on parasites, but also on humans and/or pets. Many people begin to complain of headaches, stress, sleep disturbances, etc. So it is recommended to use such devices with great caution.

Some types of fumigators also cause harm to apartment residents and pets. Therefore, before use, make sure that the device or composition can be used in a residential area.

Don’t forget to take the following precautions when working with aerosols:

• use safety glasses;
• avoid contact of the product with skin and mucous membranes;
• Before treatment, remove all food, dishes, clothing, etc. from the affected area.

Pros and cons of traps

Bedbug traps, despite the fact that they are quite effective in dealing with a small number of parasites, have a wide range of disadvantages.

Before using any device or tool, it is recommended that you familiarize yourself with its pros and cons, the main ones of which are the following:

• They do not have a harmful effect on parasite eggs. Accordingly, if there are a large number of bedbugs, it is recommended to use traps only in combination with insecticidal agents.
• Completely safe for people and pets. They can be used for an almost unlimited amount of time.
• Various devices, such as adhesive devices, are an excellent identifier that allows you to determine the presence of pests in the house.
• Devices made with your own hands do not require the investment of a large amount of money, since the cost of available materials is low.
• This method is highly effective if used to prevent the appearance of parasites in the house.

Based on the above, the following conclusions can be drawn: traps are quite effective means, the task of which is to prevent the appearance of parasites in the house, as well as to determine this fact.

Where in the apartment do bedbugs hide and rob?

Bedbugs prefer to live mainly in sofas, beds, armchairs - closer to humans. They can appear behind skirting boards and peeled wallpaper when all the places in the sleeping areas are already crowded. You can read in more detail about where bedbugs hide in the article - Where do bedbugs come from and where do they hide? Insects not only feed on our blood, but also reproduce very quickly. Having eaten well once, they can hide for a very long time. Residents of the premises will breathe a sigh of relief and think that they have gotten rid of uninvited guests. And when they completely relax, they accidentally discover that the insects have not just returned, but their numbers have increased many times and it is necessary to take radical measures, such as contacting the SES.

You can tell that bedbugs are living with you by their pink bites. For many, bedbug bites itch very much, causing severe pain. Although there are people who do not have any skin reaction to bites, this is very rare.

Pros and cons of insecticide

To finally decide on the choice of means to get rid of blood-sucking parasites, you should familiarize yourself with the main advantages and disadvantages of Dichlorvos.

Among its advantages:

Convenience and ease of use. There is no need to calculate proportions for preparing the substance. No additional tools are needed for processing. Availability in stores. You can purchase the aerosol at most retail outlets; the product is not in short supply. Price. The price is relatively low - about 100 rubles for a 190 ml can. Does not leave stains even on fabrics. Versatility. It acts not only on bedbugs, but also on many other insects. Minimum danger

The possible harm to humans is negligible (especially if precautions are followed).

Despite the fact that the drug is quite popular for household use, it is still not a panacea for getting rid of bedbugs. Its disadvantages:

• To penetrate hard-to-reach places, special nozzles are needed;
• short duration of action - up to 7 days;
• the need for repeated treatments;
• may be ineffective at high levels of infestation.

The insecticide is good for prevention, but only if the insects do not appear in too large numbers. Small doses of the product will not only not help, but will also cause insects to become resistant to the poison, so before you start treatment, you should make sure there is a sufficient amount of the drug. Usually per 1 sq. m area, 20 g of spray is consumed.

Instructions for use

In order to effectively deal with parasites, take a cylinder with “Insecticide” so that it is vertical. It is taken twenty centimeters away from the place where insects accumulate and spraying begins.

In order for the treatment to be effective, it is necessary to divide the entire surface into intended squares and thoroughly disinfect each of them for ten seconds.

This is interesting! It is better to fight insects in the warm season, since the greatest effectiveness of “Insecticide” is observed in the range from 15 to 25 degrees Celsius. As soon as the temperature becomes significantly higher or lower, it is recommended to postpone treatment.

The room must be prepared for processing. You need to take toothbrushes, baby clothes and groceries out of reach. Clothes and bedding should be wrapped in airtight bags. Pet bowls should also be kept securely hidden.

It requires very careful inspection and careful processing:

• beds;
• mattresses;
• sofas;
• armchairs;
• cracks in the floor;
• spaces behind cabinets;
• furniture;
• baseboard;
• the back of a floor or wall rug;
• spaces behind the wallpaper;
• electrical outlets;
• batteries;
• doorways, etc.

Then the windows, doors and vents are tightly closed for twenty minutes. Afterwards, the apartment must be well ventilated. It is best to create a draft so that all odors disappear.

Protective equipment

Then use a mixture of soap and soda to wipe all surfaces in the house.

Particular attention should be paid to door handles, tables, bedside tables, armrests or shelves. This cleaning is done to ensure that family members do not accidentally come into contact with the toxic substance.

The drug is quite toxic, so precautions must be taken. Before starting sanitization, you must put on thick rubber gloves on your hands and protect your face with a bandage.

Eyes must be covered with glasses.

After finishing disinfection, you need to wash or throw away the clothes you wore, take a shower and rinse your mouth thoroughly.

If you were unable to protect yourself and the substance got on your body, you should treat the areas in contact with it with soda.
