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.

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.

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. Does not affect the operation of other devices or human well-being. The cost of a Tornado depends on its power - from 1800 to 6200 rubles.
• 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.

Table: comparative characteristics of the most popular bedbug repellers

These parameters (except for the cost of the device) are indicated by the manufacturers and may differ from the actual ones.

How to use the repeller

The instructions for use are simple and banal. Remove the device from the packaging, connect it to a power source or insert batteries. 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.

What you need to know before use

When using the device you should know:

• Ultrasound only affects adults, and does not affect eggs and larvae. Therefore, the device must be turned on every 12 hours.
• If you need to get rid of bedbugs over a large area, it is more advisable to purchase several emitters at once and distribute them evenly throughout the room.
• For the best effect, it is necessary to use different means of control in combination. For example, aromatic products: a device is plugged into the outlet that emits an odor unpleasant for parasites.

For best effect, ultrasonic insect repellers are recommended to be used for two months at intervals of 2-3 weeks.

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.

Classification of repellents

Ultrasound against bedbugs is not the only option for controlling parasites. Other means are also used. They differ in their level of efficiency and electrical parameters. Each device affects people differently.

When selecting a device,

The load on the electrical network must also be taken into account.

Considering that such equipment must be used for a long period, it is important to purchase a bedbug repeller that will be characterized by low energy consumption, which will avoid increased costs for utility bills.

Fumigator

This is the name of a device that is designed to destroy/repel insects, including bedbugs. The operating principle is based on the release of a toxic substance into the air when the ambient temperature changes. However, the dose of poison is small, so there is a change in the behavior of the pests; they do not crawl closer than is permissible, but do not die.

Bedbugs are afraid of products that have a more pronounced odor, for example, ammonia, kerosene, and toxic substances. When the fumigator is turned on, insects also react to the released compounds, so they try not to fall into the zone of its influence. At best, they will go in search of a new source of food, because they do not like to be in conditions in which they feel severe discomfort.

However

there is a possibility that they will continue to reproduce, but they will attack at different times, even during the day, to which they will be driven by hunger.

Standard type of electric fumigator

The fumigator is most effective when connected directly next to the bed. The greater the distance from the device to a person’s sleeping place, the lower the effectiveness of toxic substances. There are several types of such devices:

• electrical: liquid, solid fumigant (plates, tablets);
• pyrotechnic;
• based on a chemical reaction when mixing substances, due to which steam containing a volatile compound is released (for example, Raptor aquafumigator).

In the first case, the toxic substance begins to be released when heated. When the device is connected to the network, the current changes the temperature of the heater, which leads to the release/evaporation of the insecticide. The second option operates on the principle of combustion. The wick is ignited and a volatile substance is released under the influence of high temperature.

Electronic

• If we consider the two previous types, each will highlight its advantages and disadvantages. Of course, I would like to have a device that combines all the advantages and has no disadvantages. If you have thought about this, then you should pay attention to electric models. It is this type that combines both actions of the devices and has the maximum effect. The effect is also very rapid; the pests are affected by waves one at a time, which significantly accelerates and intensifies the effect. In addition, “uninvited guests” will definitely not be able to adapt to such conditions.
• You can see the result after a few hours, just plug it in. Of course, you won’t be able to get rid of the offspring right away, but it will be enough to turn it on after a few days and the problem will be solved. Also, do not forget about preventive actions, which will protect your home.

Electromagnetic repeller

Another name is magnetic resonance device. The principle of operation is based on the device’s ability to produce electromagnetic waves. The manufacturer states that this method provides the desired effect due to the occurrence of resonance between the radiation of the device and the vibrations of the pest’s nervous system.

In fact, such a theory has no basis. Electromagnetic repellers for household use have no effect on bedbugs. If you try to use them at home, the number of insects will soon increase, since no other means have been used.

Parasites will begin to fear an electromagnetic device only if the intensity of the radiation is significant. However, in this case, people will also feel severe discomfort. It will become impossible to exist in such conditions, so such equipment is not used at home.

Electromagnetic repeller: standard appearance

Ultrasonic devices

Such devices are no more effective than the electromagnetic bedbug repellers discussed above; reviews of them are equally negative. Ultrasonic radiation helps protect an object from insects that communicate with each other in a similar way, that is, using high-frequency sound waves. Bed bugs are not such pests.

For example, mosquitoes are afraid of repellers that operate on the basis of ultrasound.

Operating principle of electromagnetic devices

Just like ultrasound, magnetic resonance pulses cause bedbugs to leave the room, but do not kill them. There are both networked and stand-alone electromagnetic repellers, and almost all of them are universal, that is, they also work against other pests.

Magnetic resonance vibrations force insects to leave dangerous territory

When using magnetic resonance devices, the following should be considered:

• powerful low-frequency radiation affects not only bedbugs and other insects, but also pets and humans;
• The electromagnetic emitter does not affect bedbug eggs, and therefore requires repeated or constant switching on for at least a month.

After turning off the repeller, parasites in most cases reappear. This happens because bedbugs cannot travel long distances and remain on the border of the device’s radiation zone, continuing to feed and reproduce if possible. In the case of an apartment building, insects migrate to neighbors.

Scented repellers

For the most part, fumigators are a means of killing insects. Devices used against house bugs are divided into several types:

• aerosol,
• burning spirals,
• smoke bombs,
• electric.

The latter, in turn, work with various active elements, including:

• records,
• pills,
• liquids,
• liquid aerosols.

According to users, aerosols are most effective against bedbugs, including the use of electric fumigators. Sprays are easy to use and do not require special equipment; they are economical and affordable.

Some types of fumigators are harmful to the health of humans and domestic animals, so before turning them on, you should carefully study the attached instructions and take safety measures!

Liquid and aerosol fumigators are most effective against bedbugs

Most aromatic repellers contain complex substances that, in a specific combination, paralyze insects. The active ingredient enters the parasite's body, and the infected bug spreads the toxin throughout the population.

When working with aerosol substances, the following precautions must be observed:

• use safety glasses;
• avoid contact of the chemical with skin;
• Before processing the room, remove food and utensils.

A smoke bomb, according to reviews, helps get rid of bedbugs, but is a rather dangerous means of combating parasites. The use of smoke bombs in houses with people is prohibited.

Animals and ultrasound

Although the human ear is not affected by ultrasound, many animals can both hear and produce it. Many rodents, small mammals, insects, as well as bedbugs use ultrasound as a means of communication.

Bedbugs have hypersensitive hearing organs and therefore can perceive incredibly high frequencies. Cockroaches have "sensory antennae" that are used to sense ultrasound. Spiders, wasps, beetles and flies have a tympanic membrane to detect ultrasound. Male mosquitoes use such frequencies to attract females. Lizards also have the ability to perceive ultrasonic vibrations.

Is it safe for people?

Ultrasonic repellers are widely used in homes, gardens and farms to successfully treat bed bugs. Commercial instruments are designed to operate in the range from 20 kHz to 100 kHz. Ultrasound above 20 kHz cannot be heard by adults, but children can hear sounds up to 30 kHz.

Almost every home has a lot of devices that emit ultrasound. A mobile phone, computer, or vacuum cleaner are sources of such a signal, but do not cause any harm to human health. Ultrasound is considered the safest way to examine pregnant women; it is this technology that the ultrasound machine uses. Ultrasound is also used in cardiac echocardiogram. According to scientific research, high frequencies cannot harm human health.

The most popular ultrasonic repellers and prices:

• Thermacell Outdoor Electronic Repellent. Price: 1,600 rubles.

• Thermacell Insect Repelling Lantern. Price: 1,340 rubles.

• Pest Reject Ultrasonic Bug Repellent. Price: 2,680 rubles.

• Home Sentinel Electromagnetic, Ionic & Ultrasonic Insect Repellent. Price: 800 rubles.

• SOARING Ultrasonic Bug Repellent. Price: 1,270 rubles.

• Clip-on Bug Repellent Fan, 2 Packs. Price: 1,000 rubles.

Interesting facts about ultrasound and mosquitoes

Male mosquitoes are the natural enemies of females of their species after breeding. Few people know that in fact, both males and females use plant sap rather than human blood as food. The mosquito has become man's worst enemy because females need protein from human blood to mature their eggs. Males never bite people, only females do this, and only after mating. This gives them the opportunity to obtain blood, which is vital for raising offspring.

And there is one more interesting feature. Females and males are at enmity with each other; more or less tolerable relations between them are possible only at the moment of mating. And therefore, after reproduction, females avoid males as best they can. The most important way to detect their presence is the 38 kHz ultrasound that males emit through their antennae. Working at this frequency, the ultrasonic repeller imitates the presence of a male for females, so they fly away.
