How electronic cockroach repellers work: types, features, reviews, tips

Greetings! Progress does not stand still, and this cannot but rejoice. There is no longer any need to cover the corners with wormwood to remove insects, and even special chemicals from pests do not always harm a person.

However, the case of the disruptors has reached a new level with the advent of electronic devices. Among them are electronic cockroach repellers. It would seem how a regular high-tech toy can prevent such tenacious parasites? I talk in detail about such repellers in my material!

Electronic Cockroach Remedy

Cockroaches Ultrasonic repellers Typhoon from cockroaches Repeller Grad Riddex and Ar-120 from cockroaches It is difficult to find a person who would not have faced such a problem in his life as the appearance of cockroaches in the apartment. The centuries-old struggle with these insects has given rise to many ways to destroy them.

From a banal hit with a slipper, people learned to act on parasites and low temperature, and deadly insecticides, and even folk remedies.

More recently, an ultrasonic cockroach repeller has entered our everyday life. Like any innovation, it has its own advantages and disadvantages.

Therefore, it is imperative that the electronic tool you prefer is effective in home battles.

Features

Ease of use is the main advantage of any electronic device against cockroaches. Simply plug the appliance into a power outlet and you don’t have to spray the apartment with toxic chemicals, move furniture or relocate households for the duration of the treatment.

Often, to achieve the maximum effect, the manufacturer of electric repellers recommends combining the device with the use of chemical or folk remedies.

And the fight will have to start all over again. Therefore, it is important to drive out insects and destroy their eggs at the same time. To do this, you can use aerosol Raptor, Raid, Global and others.

The entire range available to consumers is divided into electromagnetic and ultrasonic cockroach repellents. In appearance, the devices of both types practically do not differ, and you can only learn about the features of the device from their instructions.

Summarizes these devices is that when plugged into the outlet, the device repels insects in a certain radius of action. The larger this area, the more efficient and expensive the product.

It is worth noting that many of the models on the market are ineffective in practice, therefore, the choice of repeller must be approached very responsibly.

Ultrasonic devices

The ultrasonic cockroach repeller is very popular among consumers today. The principle of operation of such a trap is based on the creation of ultrasonic vibrations, the wavelength of which is not perceived by the human hearing organ, but for insects it is extremely unpleasant.

Manufacturers assure that by inserting the device from cockroaches into the outlet, it is possible to clean the room from insects. It is important to understand that ultrasound does not kill the parasite, but only scares it off. Therefore, do not trust sellers who claim that an electronic cockroach repeller is capable of killing them.

Ultrasonic Repellers

Electromagnetic and ultrasonic devices only scare off cockroaches. You do not need to trust the advertisement stating that such devices can kill insects - this is a hoax.

The principle of operation of the trap is quite simple: there is a bait inside the house, the smell of which attracts cockroaches. Trying to eat it, the parasite dies under the influence of electric current. Electric traps should be periodically cleaned from dead insects and change the bait.

Ultrasound duo

Among modern electronic devices, the Ultrasonic Duo is the most advanced device. The high-frequency band that the device creates affects the nervous system and hearing of not only mice and cockroaches, but also moths, flies, ants, rats and spiders.

Ultrasound can scare away insects, causing them pain, under the influence of which the "unsolicited neighbors" have to leave the house.

The ultrasound created by the device from cockroaches is safe for people and most pets. It does not affect the work of other electrical appliances and telecommunications facilities.

The device has 3 operating modes, which allow you to automatically change the frequency from 25 000 to 65 000 Hz. The exposure radius of the ultrasonic repeller is about 550 square meters. m. The result of the work will be on the face in a few days.

Such an ultrasonic trap acts only on adults, it does not affect eggs and larvae. Therefore, to avoid the repeated spread of cockroaches, the device is best used in combination with chemical or folk remedies.

Pest reject

Modern American-made Pest Reject repeller. The range is about 200 m. One of the most effective devices that helps to get rid of not only cockroaches, but also other parasites in the house. At first it is recommended to combine its use with insecticidal agents and traps for cockroaches.

Typhoon LS 500

Typhoon LS 500 - an ultrasonic repeller of mice and cockroaches of domestic production.The radius of the device is about 80 m, that is, it is enough to have one cockroach repeller in the apartment.

The presence of a long cord makes it possible to place the device at a distance. Typhoon can be ordered not only on the Internet, but can also be bought at many hardware stores in Moscow at a price of about 1000 rubles.

Wk-600

The powerful WK-600 insect repeller is often used in food processing plants. Ultrasound from cockroaches is able to protect entire workshops and halls. Its cost can reach 5000 rubles.

Hail

Ultrasonic device Grad domestic production repels not only insects, but also small rodents. Sound negatively affecting their nervous system forces them to leave their habitat. Distinctive features of the device are:

• Reliability;
• Efficiency;
• Long term of operation;
• Simple application method.

GRR09

An ultrasonic device with a GRR09 switch provides cockroach repellent without the use of harmful chemicals.

The presence of three modes makes it possible to deter fleas, mosquitoes, small rodents, cockroaches and even martens. The area of ​​action is 40 square meters. m

EcoSniper

This magnetic resonance cockroach repeller developed in Hong Kong. The device is capable of emitting low-frequency waves that are detrimental to the nervous system of cockroaches, which makes insects leave their favorite places.

But contrary to the claims of the manufacturer, the reviews on the EcoSniper ultrasonic cockroach repeller say that the device is not effective enough.

The analogues of this model are:

• Ixus KY-6182 is a cheaper option with similar characteristics. You can purchase it through the online store;
• Zenet XI-90;
• Air Comfort XI-90.

Tornado

There is a whole series of Tornado devices of domestic production. Of particular interest is the OT 02 Tornado repeller model. In addition to sound vibrations, the device can also emit light waves.

It is important to correctly install the ultrasonic repeller not only in height, but also at the desired slope. Failure to comply with the manufacturer's recommendations may result in a lack of a positive result.

Banzai LS927

Taiwanese insect repeller, according to consumer reviews, has a much more effective effect on cockroaches than many of its brethren.

Thanks to their high power, insects really leave the room. However, the manufacturer warns that the waves emitted by the ultrasonic repeller are unsafe for the health of people and pets.

Electromagnetic devices

Electromagnetic repellers act on the nervous system of insects by electromagnetic waves. The cost of such devices varies depending on the range.

Ridgedex repeller

This democratic electric cockroach repeller has an area of ​​about 200 square meters. m. The universality of the device lies in the presence of settings that make it possible to get rid of not only insects, but also from small rodents.

AR-120

This cockroach device is designed for an area of ​​up to 50 square meters. m. The expiration dates set by the manufacturer (from 2 weeks to a month) depend on the level of infection in the room. The device is quite expensive, the price is about 2000 rubles.

Any electronic device from cockroaches is designed for a long period of work. It should not be plugged into an outlet, not only at night. With irregular use of the repeller, the likelihood of repeated spread of insects is high.

Reviews

Ekaterina, Samara: We installed a Pest Reject repeller in the country - we got rid of not only cockroaches, but also mice. In addition, mosquitoes did not bother in the evenings.

Sergey, Moscow: We installed GRR09 insect repeller in the bathroom. A few days later there were no cockroaches, but in other rooms the pests moved freely.

Olga, Volgograd: I want to express my deep gratitude to the producer of the Ultrasonic duet. There are no cockroaches in our house for more than 3 months.

The seller advised not to turn off the device for a long time, only then you can achieve the effect. So we did, the result is on the face.

Using Electronic Cockroach Repellers

Cockroaches are warm-blooded insects that came to us from tropical countries and settled in houses and apartments. Cockroaches are very unpleasant neighbors that cause significant harm.

And although recently the total number of cockroaches has sharply decreased, people who are "lucky" to get hold of such neighbors are looking for ways to get rid of them as soon as possible.

Some do not want to spend time fighting cockroaches, or simply don’t know how to deal with cockroaches, and therefore they call health workers.

Others fight cockroaches on their own using various methods - poisonous agents (aerosols, gels, pencils), traps, various folk remedies, unpleasant odors, etc. One of the effective ways to get rid of unpleasant insects is an ultrasonic cockroach repeller.

Ultrasonic waves act on the nervous system of pests, causing them to experience unpleasant sensations, as a result of which the cockroaches themselves leave the home.

In addition to cockroaches, ultrasound is also afraid of other harmful insects - bugs, fleas, ants, mosquitoes, etc. When working, electronic means against cockroaches are safe for people and animals.

Benefits of Electronic Cockroach Remedies

The use of ultrasound from cockroaches is good because such products are safe for people and animals, do not affect the environment.

Electronic repellers are easy to use - just plug the device from the cockroaches into a power outlet and the cockroaches will leave by themselves. They are convenient, do not bother anyone when used.

Ultrasonic repellers protect a sufficiently large amount of space, are safe to use, absolutely inaudible to people.

Due to their low power consumption, they can work around the clock without overheating and without consuming a large amount of electric energy.

Using ultrasonic repellers, you can get rid of cockroaches in a short time, without putting much effort into it, without wasting time, without using toxic substances and without harming people, pets and the environment.

Do repellers help get rid of cockroaches

Cockroaches are carriers of various dangerous diseases and infections. They create dirt, spoil food, and can cause allergies.

Under unsanitary conditions, parasites begin to multiply even more and faster. There are a huge number of effective methods for pest control.

The principle of operation of ultrasonic repellers

The device is connected to a power source, processes pulses of the desired frequency, high frequencies affect the nervous system of parasites. Insects are uncomfortable to exist in such conditions, and their number is significantly reduced.

Kinds

Devices that repel cockroaches are distinguished by universality, parameters, properties, the principle of operation and radius of action.

Ultrasonic

The device with the help of ultrasound does not kill, but repels cockroaches. Waves travel far enough. Only at high frequencies do cockroaches leave their habitat. Such devices do not have a negative effect on the human body and pets.

Magnetic resonance

Devices emit electromagnetic waves of low frequency. This causes insects to change their place of residence. The safety of the repeller is directly dependent on its power.

Industrial magnetic resonance repellers are considered more effective, but they badly affect the human body.

Electrofumigators and aquafumigators

Electrofumigators against cockroaches look the same as their counterparts against mosquitoes. For the operation of the device, special tablets are used, which, when heated, emit a specific smell. The scent spreads throughout the room and repels pests.

Compared with other devices, devices have a low cost, are convenient to use, and are quite effective. Cons: The substance can have an unpleasant odor and damage health.

Tips for choosing the right model

The market is crowded with different types of repellers. Practice shows that not all proposed models cope with their task. Highly effective repellers are more expensive and eliminate pests.

And dubious, with low cost, can not scare away even mosquitoes, to say nothing of cockroaches. In this regard, it is worthwhile to adhere to certain tips when choosing the right model:

1. If the residents of a house or apartment acquire an expensive and without a doubt a powerful device, then staying at home during its operation (approximately 4 weeks) is not safe. The best solution would be to move out of the living space.
2. There are devices whose effect extends to no more than a square meter. Such devices are best used in rooms where people do not live, or on the street. It is allowed to place several repellers in one room, which operate at a distance of up to fifty square meters.
3. You must carefully select the type of food. If you went on a trip, are outdoors, it is better to use a battery-powered repeller. At home, it is recommended to use the mains supply method.
4. In order not to stumble upon a fake by mistake, it is best to buy the device in specialized and trusted stores.
5. When buying, you should pay attention to the range of the repeller. The device is not able to influence parasites through obstacles (furniture, walls, carpets).

How to properly install and use electronic repellers

The effectiveness of the repeller directly depends on the ability to properly place and apply it. To do this, there are some rules that you must adhere to:

• It is advisable to use several repellers at the same time. This will certainly help get rid of a large number of parasites. It is allowed to place one device in each room.
• In order for the device to capture a large area, it should be placed at a height of 1 m and only in a vertical position.
• Due to obstacles in the room, the effectiveness of the ultrasonic repeller is reduced. The solution to this problem is to place several devices in the room.
• After installing the device, be sure to monitor the condition of people nearby.If the action of the device negatively affects them, it is better to refrain from using it and choose another way to combat parasites.
• If the equipment has any damage or does not work correctly, then it should be returned for repair. It is not permitted to use a damaged machine.
• Together with the repeller, other methods are allowed to be used to get rid of cockroaches.
• Experts believe that ultrasound does not give an instant result. Ideally, the repeller should work for about a month.
• The device can not be disconnected from the network even for a short time, otherwise the cockroaches will return.
• After installing the device, you must monitor its temperature. Overheating or excessive cooling must not be allowed.

How effective are repellers

For a long time, the fight against parasites has been ongoing. Chemical and toxic substances are used, but this is an extremely unsafe method.

Animals and people are not able to perceive such a frequency, but harmful insects are subject to its influence. Fumigators best drive cockroaches away if sound waves of different frequencies are used.

Causes of apparatus inefficiency from cockroaches

Scientists conducted various experiments and found out the way insects communicate using ultrasonic signals. Most often, mosquitoes communicate in this way.

Cockroaches are less sensitive to this type of repellers. The study showed that adults, when exposed to ultrasound, actually leave the habitat, but this is not so scary for young people.

However, it cannot be argued that the repeller is completely ineffective. Productivity may be due to several reasons:

1. The equipment is incorrectly selected. Before buying, carefully study the area of ​​the apartment or house. Based on this information, a repeller suitable for the living area is selected.
2. The device is not installed correctly. Ultrasound does not pass through walls and other obstacles. Sound frequencies are also reflected off a hard surface and absorbed by soft objects.
3. They saved on quality and acquired a cheap repeller of an unknown brand that did not cause any confidence.
4. Inattention. If the battery is discharged, the device stops sending ultrasound and becomes completely useless.

Cockroach repeller gives a good result if you follow the instructions and advice of the manufacturer. High-quality repeller can be purchased from 900 to 7000 rubles. Talk to specialists if you have any difficulties choosing.

It is necessary to take into account the parameters, properties and characteristics of devices in order to know for sure which is the best and most suitable for your home.

Electronic Cockroach Repellers

Cockroaches are the oldest creatures. Over the centuries of forced coexistence, many means have been invented to combat them. Ultrasonic repellers appeared not so long ago, but now they are becoming more and more popular.

Of course, repellers are somewhat more expensive than conventional means, but after using them there is no need to clean insect corpses.

To activate the device you only need to connect it to the mains. It works completely silently. But the result of the repeller will not be immediately visible. Most likely, this is its main disadvantage.

It will take several weeks to completely destroy the cockroaches. Manufacturers talk about the absolute effectiveness of repelling devices. But is it?

What is the matter here. In this article we will try to give an objective assessment of the work of ultrasonic cockroach repellers.

How repellers work

Such devices are humane means, because they do not destroy cockroaches, but simply expel them. The cockroach is unbearable to hear these sound vibrations, and they are in a hurry to get away.

Almost all modern models have the ability to control the power level and frequency of the signal. The ultrasound emitted by the device may be at the frequency at which the insects send alarm signals. From time to time, the frequency of the signal must be changed to prevent insects from getting used to a certain signal level.

There are types of repellers aimed at repelling other insects, such as mosquitoes. Once invented a device that makes sound made by bats. Not all insects are affected by ultrasound, but cockroaches do not belong to them.

Ultrasound Against Cockroaches

The complexity of the moment lies in the fact that adjusting the desired signal level is not easy. If the signal is too weak, then it will not work on cockroaches, and too strong a signal will drive away not only cockroaches, but also cats and dogs.

The specialists selected exactly the level that negatively affects cockroaches, without causing any inconvenience to other living creatures in the apartment. But to achieve absolute efficiency, the signal must be very powerful.

Experts agree that repellers cannot completely get rid of insects, with their help you can only reduce their number. This is due to the fact that when exposed to ultrasound, cockroaches lose their ability to reproduce.

But from manufacturers of deterrent devices you will not hear this. They unanimously reiterate that their products are 100 percent effective.

And consumers are attracted by the fact that the device only needs to be connected to a power source, and it will save them from the presence of insects without spilling poisonous powders. After all, we are not so willing to deal with the application of toxic substances in our apartment.

But unfortunately, one hundred percent efficiency from the work of repelling devices is not always possible to achieve.

There is no shortage of ultrasonic repellers today. They are sold both in specialized stores and on the Internet.

A lot of types of such devices are produced in China. But buying them is not recommended, as they are of poor quality.

Below will be presented the best brands of cockroach repellers that you can buy in our country. Introducing our TOP 5.

Typhoon LS 500

This device emits ultrasonic signals that are completely not perceived by humans or pets.

But cockroaches hear this signal, and they do not like it at all. Here the possibility of the insect getting used to the signal is completely excluded, since its level is subject to change.

Manufacturers talk about its absolute efficiency, but it’s hardly worth trusting, so at the end of the article you can read real user reviews about this device.

The device can be powered by a household electrical network. The emitter is enclosed in a box having a white color. A typhoon can be installed anywhere.

Most often it is used in residential premises, but it is used both in warehouses and in other areas. When installing this device, you need to keep in mind that various obstacles will greatly interfere with its operation. These include wall partitions and furniture.

The location of the device in the room should be such that the signal arrives in all its corners. To do this, it is better to remove excess objects. There is another option - to install several repellers.

And if you use the device in a multi-room apartment, then you definitely need several devices. Also, several devices will have to be used if the protected space exceeds 80 square meters. Typhoon has both its pros and cons. Let's talk about this in more detail.

Pros:

• When installing the device does not need any complex actions, it just needs to be connected to a power source, and it is activated.
• He is not making noise. He also does not emit odors.
• The device can not be turned off for a long time.

Minuses:

1. There have been no studies regarding the safety of sounds emitted by the device. This data is based on manufacturers claims.
2. The cost of the device is much higher than the price of chemicals, which, by the way, can destroy insects very quickly. But the effect of the repeller will not be immediately visible.
3. Typhoon fakes sometimes appear on sale.
4. Under the influence of a Typhoon, cockroaches do not die, they only leave the apartment, which may be fraught with their return.

Typically, cockroaches are most in the kitchen, and this is where it is worth installing a repeller. Once again, it is worth recalling that various obstacles greatly reduce the effectiveness of the device.

The first results can be seen in a few days. It is impossible to name a more accurate time, since much depends on the number of parasites. Remember, the device is unlikely to completely eliminate the presence of parasites, it only reduces their number.

IXUS KY-6182

The characteristics of this device are identical to the characteristics of the previous device. It emits ultrasonic vibrations that negatively affect the nervous system of cockroaches.

This encourages them to leave the limits exposed to waves. But he also has some differences from the previous device - this is a lower price and lower weight.

According to the manufacturers, this device does not affect people and animals in any way, but it forces insects to leave the territory under its control. The signal propagation area is 80 meters. The price is 820 rubles. It is sold both in ordinary stores and in chain stores.

ZENET XJ-90

It's no secret that ultrasonic repellers have gained a bad reputation among users. The manufacturers of this device are aware of this, and they say that they have created a fundamentally new device that scares off parasites not in words but in deeds.

The effective area is 40 meters. The device consumes little electrical energy. There is a nightlight function that can be turned on and off at the request of the user.

Appearance is modern, and it will harmoniously fit into any interior. According to the manufacturers, the device does not break at all. It is used in rooms of various types.

AIR COMFORT XJ-90

According to manufacturers, this device is designed to scare away a variety of insects. It runs silently. No harmful substances are released.

Use in rooms of all types is possible. If the area to be covered is more than forty meters, then several devices must be used.

About the advantages of this device:

• no smells;
• covers 40 meters;
• for humans completely harmless;
• there is no need to insert poisonous records.

PEST REJECT

But this is a universal device. According to manufacturers, he expels not only insects (cockroaches and mosquitoes), but also rodents.

PEST REJECT - a real shield against insects entering the apartment. It emits electromagnetic waves unbearable for parasites.

These fluctuations diverge over the entire area where the wiring is carried out. In addition, the device generates ultrasound.

The complex of these actions provides high efficiency. But all of the above are manufacturers' claims. Let's see what users say about this.

Should I buy an electronic cockroach repeller

Among the many different means for controlling insects, electronic cockroach repeller is very popular.

Those people who have already encountered this problem know about how difficult it is to get these parasites out of the living room.

Not a single remedy helps the first time. Therefore, chemical sprays, traps, crayons and other drugs have to be used again and again.

The dream of a man who was attacked by cockroaches is a means of instant effectiveness. This is exactly what manufacturers of electronic repellers describe their products.

But lately, the range of repellents against cockroaches is becoming more and more. Manufacturers claim that the operation of the device is safe for humans, but also harmful to insects. Therefore, one device can easily replace chemical insecticides in aerosol, traps, powders and crayons.

What are electronic cockroach repellers

In recent years, the range of such products has expanded significantly. Electronic repellers have become in demand due to safety for humans and ease of use.

Electronic repellers differ in the type of exposure to cockroaches. They can emit ultrasonic or electromagnetic radiation. At the same time, experts assure that such waves are absolutely safe for humans.

In turn, those who have already managed to test the action of electronic cockroach repellers in their home, note that there was no discomfort during the operation of the device.

Ultrasound repellers are very easy to use.The device is absolutely not difficult to connect to the network, and after that powerful waves will begin to come out of it.

They should be perceptible to cockroaches, but the person does not feel them. Thus, unbearable conditions are created for parasites to live and eat, so they just go away to look for a more favorable territory.

According to manufacturers, ultrasonic devices should immediately act on cockroaches. However, not all products of this type are quite effective.

In this case, only one thing can be said. Do not expect that a cheap ultrasound machine from an unknown manufacturer will be able to cope with pests in an apartment or at home. Such a purchase will be a waste of money and effort.

The second type of instrument is an electromagnetic cockroach repeller. The instructions for such devices say that after connecting to the mains, the device immediately creates a magnetic field in a certain area, which cockroaches cannot take.

The waves must act on their nervous system, so the parasites stop eating, multiply, and also try to quickly move away from the dangerous field for them. For a person, spending time inside a magnetic field should be harmless.

In appearance and type of inclusion, both varieties of repellers are exactly the same. Therefore, more often than not, on what exactly is the principle of operation of the apparatus based is possible only from the instructions.

When choosing a device, you need to pay attention not only to such a moment as the principle of operation, but also to the range of the device.

If it turns out to be too small, the repeller will not be able to perform its work efficiently, and cockroaches will periodically flicker in the person’s field of vision.

The price of the electronic device directly depends on the range of the electronic device. The availability of additional options is slightly less likely. It is worth noting that when it comes to the cockroach repeller, there is no need for any super-functions.

They can only run away in search of a more favorable place, but parasites cannot be directly exterminated with the help of special waves.

Therefore, if in one room it was decided to use an electronic repeller against cockroaches, it must be borne in mind that a problem may arise in the next room or apartment.

The principle of operation of ultrasonic devices

With regard to these devices, it is worth noting that cheap repellers will not work. They can only drive the cockroaches out of the kitchen, and they will move to the ventilation or to the bathroom and will still occasionally flash before people's eyes.

The big advantage of such devices is safety. They are not toxic, like aerosols and other forms of insecticides, and the waves themselves do not pose a danger to humans.

In addition, it is unlikely that it will be possible to find a remedy for cockroaches, which would be easier to use. Simply plug the device into a power outlet so that it begins to function actively and disperse parasites. But only high-quality ultrasonic cockroach repellers work this way.

Ultrasound machines are not capable of killing cockroaches. They work on a certain wave, which should inform the cockroaches that they are in danger.

As for cockroaches, the question is complex, since they should not respond to ultrasound. But manufacturers assure that all insects in a certain radius scatter after the device is plugged in.

How useful are ultrasonic repellers

If you understand in more detail, you can understand that devices of this type will work, but you should not expect a quick effect from them.

If you strengthen the action of the waves, then they will be dangerous not only for cockroaches, but also for humans, therefore, such devices cannot be used in a residential building.

Nevertheless, it cannot be argued that such devices give absolutely no result. Studies have shown that prolonged exposure to ultrasonic waves on parasites makes them weakened.

As a result, they cease to multiply, and after that they simply die out. In addition, such an effect causes persistent disorders in the nervous system.

Therefore, if you try to remove cockroaches with ultrasound, you need to be patient. But there is no guarantee of their complete extermination.

To a greater extent, you can count on the fact that the number of parasites in the house will decrease. This is due to the fact that the ultrasonic repeller prevents pests from multiplying.

Popular ultrasound type repeller models

Nowadays, a wide range of products from this category is offered. In the domestic market, both Russian, and Chinese, and European models are presented.

One of the sales leaders is the Typhoon LS500 device. It is convenient to use, since it has a long wire, so it can be used even away from the outlet. The cost of such a device is 900 rubles.

Most often, such devices are used in catering. The price of the device reaches five thousand, and its weight is slightly more than half a kilogram.

According to user reviews, the most useless option will be the Air Comfort and Zenet device. This is the same device, but under different names.

After one of them discredited itself as completely useless, the manufacturer tried again to put this device on sale, but under a different name.

However, this device has one undeniable minus, namely the excessive action of the waves. They are so powerful that they negatively affect not only cockroaches, but also people with pets. You cannot keep the Banzai device turned on in the bedroom or in the resting place.

The worldwide network has a lot of video rollers on how to make an ultrasonic cockroach repeller with your own hands.

But, if the master does not have a clear idea of ​​exactly how such a device works, you should not waste time in vain.

Should I buy an electromagnetic cockroach repeller

The principle of operation of the device in this case will not differ much from ultrasonic devices. And the efficiency is almost the same.

But in theory, everything is very different from reality. As a result, devices based on magnetic waves were no more productive than ultrasonic counterparts.

And yet, in our time, the choice of such units is very large. One of the most popular is the Eco Sniper AP120 device.The cost of such a device is 800 rubles.

But this repeller has a cheaper Chinese counterpart. At the same time, experienced users note that the action of both the original and the fake is no different.

In addition, it is worth highlighting and the device, which was called Pest Redzhekt. This device generates electromagnetic radiation, which should repel parasites.

But this is in theory, but in practice, everything comes out a little differently. Moreover, the manufacturer himself admits that the device may be ineffective.

Therefore, the instructions indicate that Pest Reject works better if used together with sticky tapes and cockroach traps.

But experienced users claim that without a device, and with it, there is no difference. All work on the destruction of parasites is done by traps, not an electromagnetic field.

Which repeller choose consumers

It can not be argued that no tool based on magnetic waves will be effective. There are different reviews about the same device.

Cockroaches, rats and other pests react negatively to such radiation, so they immediately flee in search of a more suitable place.

But powerful ultrasound and a magnetic field are harmful not only for parasites. They have a negative effect on human health. In addition, animals also suffer from the waves.

In concluding, it is worth noting that insecticides are still a more reliable option for the elimination of cockroaches. No matter how hard scientists try to invent an apparatus that will immediately remove all parasites from the living quarters and at the same time be safe for warm-blooded ones, nothing comes of it yet.
