Ultrasonic cockroach repeller is slow and not always reliable

An ultrasonic cockroach repeller is quite expensive, but it is not an ideal insect repellent. There are many popular models advertised in the market, but there is no guarantee that the customer reviews are genuine. Use only in combination with other exterminators

Ultrasonic electronic insect control devices claim that their high-frequency sound waves are insect-resistant.

However, simply plugging in one of these devices probably won't end your troubles. It's important to understand exactly what these devices can do before investing in them.

The operating principle of ultrasonic repellers

If you take a deep dive into the different models of repellers, you will find that the research on their effectiveness is mixed. In general, some ultrasonic pest control devices show some results with certain pests. But all this is very vague and unreliable.

These products are by no means a quick fix and none of them claim to be 100% effective on any pest, so they should be considered as a possible contribution to an overall pest control system rather than a magic weapon.

Types of repellers

Electronic devices for fighting Prussians are compact devices that begin to work immediately after being plugged into a power outlet. The products create electronic waves or sounds inaudible to humans that are unbearable for cockroaches.

The devices consist of a high-frequency pulse generator and a speaker that amplifies them and transmits them to the stated distance.

Depending on what type of pest control is used, the devices are:

1. Ultrasonic. High-frequency sounds put cockroaches in a state of panic, which is why the insects leave the home.
2. Electromagnetic (magnetic resonance). They create an electromagnetic field that has a depressing effect on the nervous system of Prussians.
3. Combined. Both types are combined.

It is visually impossible to distinguish one type of device from another. The devices do not have any distinctive features or characteristics, and the method of action is indicated only on the packaging.

The efficiency and price directly depend on the range of the device: the larger the area the device cleans of pests, the more expensive it will cost the apartment owners.

Kinds

It is believed that these universal devices differ in parameters, properties, operating principle and range. If you think critically, these devices seem too good to be true. I mean, you just buy an inexpensive gadget, stick it on your wall, and you're done with all your cockroach problems? No traps, poisons or even effort? Hm …

Ultrasonic

Each device emits high sound frequencies that reflect off hard surfaces and create severe auditory stress for cockroaches. This prevents them from happily living and reproducing in your kitchen, so they go elsewhere. Blocks begin to push away immediately after connection.

The service life of the device is 3-5 years. While the LED indicator is flashing, the device is still working.

Ultrasonic waves do not bother cats and dogs. However, it can poison the lives of rodent pets such as rats, hamsters or guinea pigs.

The blocks do not interfere with pacemakers, garage door openers or any other electronic equipment.

Magnetic resonance

The devices emit low-frequency electromagnetic waves, which are unpleasant to cockroaches. They leave for another resort. The safety of a repeller directly depends on its power. Devices emitting low frequencies are unproductive: the devices only repel pests without killing them, but do not harm people and animals. Industrial magnetic resonance repellers are considered more effective, but they have a bad effect on the human body.

There is a preventative, barrier option. Just a magnetic insect screen. An effective way to prevent pests and insects from entering your home. The screen has a magnetic seal that is easy to remove and clean. It is designed to be virtually invisible and will not cause any damage to your windows.

Electrofumigators and aquafumigators

A fumigator is another huge solution when it comes time to disinfect premises infested with crawling and flying insects.

The very fine particles released by the fumigator spread quickly into areas that are difficult to reach with sprays and aerosols. The electric fumigator produces a dry mist with strong penetrating power. The aquafumigator accordingly distributes tiny drops of water containing poison.

The fumigator is an ideal solution for treating commercial premises and hotel rooms, for areas where electrical and computer equipment are stored, in libraries, etc. It does not leave soot or stains.

Aquafumigators work on the principle of the effect of a reaction to the dissolution of a substance in water. Fumigators do not require a lighter or matches to activate: simply pour water into the bottom of the container up to the dotted line to cause the insecticide to spread throughout the room. There is no combustion or use of fuel. Heat is limited, and the use of the fumigator is without the risk of explosion or flammability.

Precautionary measures

A fumigator, which is an effective insect repellent, requires some precautions. Windows must be closed, people and animals must be removed, dishes and food must be hermetically sealed. You need to let the fumigator act for 4-5 hours. Then the room needs to be ventilated.

Tips for choosing the right model

Just choose a reputable brand. Don't try to save money. Their effectiveness has been poorly proven, and cheap crafts will bring you nothing but loss of money.

Why is it profitable?

The ultrasonic device for cockroaches is notable for the following advantages:

1. Drives out pests. All models eliminate insects. Many products repel not only cockroaches, but also bedbugs, fleas, ticks and rodents. If you follow the manufacturers' instructions, it takes no more than one month to leave the entire population of animals, and they do not come back. Not all anti-parasite products can boast such effectiveness.

2. Requires minimal effort. It’s easy to use cockroach repellers - customer reviews indicate this. We connected the device to the outlet and that’s it. Nothing further is required from you - the insects are expelled automatically. It is only important to place the device in a place where nothing will interfere with the propagation of ultrasonic waves.

3.Helps you save money. Any solution against pests requires money. In this regard, sound devices are more profitable than chemical products. If you buy one or several devices, you will spend no more than a few thousand rubles. Then, for many years, you pay a pittance for electricity consumption - and that’s it. You spend more money on chemicals over the same period of time.

In addition to all of the above, the ultrasonic cockroach repeller can work continuously for many years - the electronic filling has a corresponding resource.

How to properly install and use electronic repellers

1. Buy both ultrasonic and electromagnetic repellers.
2. Ultrasonic waves reflect off hard surfaces in a room and do not pass through walls, while electromagnetic energy penetrates walls. Essentially, electromagnetic waves pulse through the home along electrical circuits. Therefore, if you bought a device for ultrasound only, you will need to place it in every room. On the other hand, you can use one ultrasonic + electromagnetic repellent for every 300 meters if you have a large house.
3. Look for non-repeating waves so that cockroaches don't get used to the sound over time. Some cheaper products don't mention whether they emit repeating waves or not.
4. Use enough appliances
5. Don't block ultrasonic waves from pest repellents with furniture. Position the repellers wisely for maximum results: hard surfaces reflect ultrasonic waves, while softer surfaces absorb it. For this reason, you should not place the device behind the sofa because the sound waves will be absorbed.
6. Place them lower on the walls

Tips for choosing a device

To choose a good cockroach repeller, it is worth considering a number of key criteria for evaluating models:

• device dimensions;
• repeller power;
• functional fullness of the model;
• method of powering equipment.

There are devices from foreign and domestic manufacturers on the market. Based on customer reviews, it can be argued that the following models of devices have become the most popular and well-proven:

1. Tsunami. Product from a domestic manufacturer. Powered by mains. The device is compact in size and can operate in an unheated room. When you turn on the equipment, a blue indicator appears on the device body and a ticking sound is heard, which “speaks” of a constantly changing wave frequency. The repeller does not have advanced functionality. Can be used in a room up to 200 m2.
2. Electric cat Turbo. The device is capable of operating in a room up to 400 m2. The domestic repeller operates from the network and in autonomous mode changes the frequency of ultrasonic oscillations. In this case, both light and sound influence the pests. The device can be turned on during the day and at night.
3. Hail. In the ranking of the best repellers, this device is the most powerful - it is capable of expelling cockroaches from a room of up to 1000 m2. The equipment can be used not only in the room, but also outdoors - the effectiveness of the Grad does not change when conditions change. The equipment is powered from the mains, battery, cigarette lighter. The power indicator of the device can be adjusted . The model has advanced functionality and is capable of operating in the following modes: silent, influence on mosquitoes, repels rodents, exterminate small pests (can scare off cockroaches, ants, beetles).
4. Pest Reject. American device model. Equipment is used on an area of ​​no more than 200 m2. Judging by customer reviews, the device is considered one of the most effective, fast and reliable. The model can be used in the fight against cockroaches, moths, ants, and mosquitoes. The repeller is even more effective when traps are used together.
5. Clean house. Model from a Russian manufacturer. Can be used in rooms up to 150 m2. The repeller emits ultrasonic waves all the time without changing their frequency. The functionality of the device has not been expanded. Among the shortcomings of the equipment, it is important to emphasize the impossibility of using the device in a room without heating.
6. Typhoon. The country of origin of the device is Russia. The model is made in the shape of a square, it affects pests all the time by changing the frequency of ultrasonic radiation. Reviews about the device are satisfactory - after 1-2 weeks the parasites partially disappear.
7. Ultrasonic duet. A favorite among competitors. The device operates in three modes, differing in ultrasound frequency. The range is about 550 m2. The first effect from using the device can be noticed after 2-3 days.

How effective are repellers?

Some studies conducted under ideal laboratory conditions show that ultrasonic sound can be fatal, so the humane idea of ​​pests simply running out of your property with a bad headache isn't entirely true either. But due to the variable nature of pest infestations, these results have not been replicated in real homes. Researchers using higher quality ultrasonic generators have shown that sound can be effective in disrupting the mating or feeding habits of certain insects and animals. These generators, however, are several levels above any consumer-available device, which cannot reproduce complex sound patterns and prove to be largely useless.

They emit ultrasonic sounds at frequencies of 22-65 kHz. These sounds are too loud for the human ear to detect - much like a dog whistling.

Insects and other pests can hear them quite easily, though. For them, sounds are extremely annoying and they try to avoid them.

The controversy arises because during the first few weeks of use, pest activity actually increases because the sounds excite them and drive them out of their homes. After this, insect activity decreased sharply.

But if you choose this method of struggle, you need to approach ultrasonic testing not as a black or white proposition, but as a game of percentages. Play numbers and you will be happy. Want perfection, and nothing will satisfy you.

Terms of use

Experts advise adhering to the following rules to ensure that your network-connected tool operates at maximum productivity:

1. The device is placed in close proximity to the suspected colony of cockroaches.
2. The device must not be blocked by furniture, interior items or other obstacles.
3. The repeller is connected in a vertical position.
4. The height of the device should not exceed 90–100 cm from the floor level.
5. To ensure that insects leave your home, using the device once is not enough. The repeller must operate around the clock for at least 14 days. After 3 weeks, the eggs hatch into larvae that were not affected by radiation or ultrasound before, so the treatment is repeated.
6. When purchasing, it is recommended to carefully study the instructions: in addition to the power button, such devices often provide the ability to regulate the radiation power.
7. It is prohibited to use faulty or broken devices and avoid getting liquid into them.
8. The device should not be overheated or overcooled, so it is advised to observe the temperature regime in the room where the device is used.

Reasons for the ineffectiveness of the device against cockroaches

Unfortunately, the science on ultrasonic repellers for cockroaches and other pests is very shaky.

Ultrasonic sound waves have a frequency higher than what human ears can hear, but cockroaches can hear them. The sound is designed to irritate cockroaches and prevent them from building their cozy worlds near the source of noise.

But this only makes sense in theory. In fact, some cockroaches seem to get used to the noise, while others simply don't bother at all.

The most effective brands of ultrasonic devices

"Typhoon"

A device from a Russian manufacturer, outwardly very reminiscent of an old, Soviet-era radio.

This is a small square box with a power cord. According to the manufacturer, the ultrasonic cockroach repeller is capable of operating at different frequencies.

It has two modes: the first is a weak ultrasonic signal, the second is a stronger one.

The range of action (if, again, you rely on the honesty of the manufacturer) is approximately 80-82 meters.

Unable to withstand the painful sounds, cockroaches leave the room within 7-14 days.

According to buyers who have already tested the device, Typhoon is relatively effective, although it does not produce particularly impressive results.

The price of the device is about 1000 rubles or a little less.

American made cockroach repeller – Pest Reject

The American manufacturer confidently states that his brainchild works on an area of ​​about 200 square meters, but it produces noticeable results only after a week of using the device.

What is especially interesting is what is written in the instructions for the device - in it the manufacturer recommends using this repeller in combination with the use of gels and traps for cockroaches.

It is necessary to expel insects from your home in this way for at least seven days. Of course, the effectiveness is obvious, because the poison and traps will do their job, most of it, even without the help of a repeller, and the manufacturer will be able to sleep with a clear conscience.

But the price for such a cunning device is low, only 600 rubles.

A device with the pathetic name “Tornado”

This is another invention of our Russian engineering geniuses. In their opinion, it is this device that includes those important characteristics that are necessary to create the most uncomfortable living conditions, as well as the rapid reproduction of cockroaches.

The device creates a powerful ultrasonic signal without causing any harm to pets and people.

It has no analogues, but our manufacturers are honest with their customers: they advise not to expect instant results, since cockroaches will begin to leave your home after 2 or even 3 weeks.

As for the price, it is within a thousand rubles.

Repeller "Banzai"

If you do not trust American developments, and do not strive to support the Russian manufacturer always and in everything, then perhaps you will like the Banzai repeller.

It was developed in Taiwan, and this device is considered one of the best and most effective. Reviews from enthusiastic buyers say that the insects actually leave the apartment within three weeks.

But the device itself is not entirely safe. For example, it is prohibited to install cages with pets or sleep near it, since the device emits an unpleasant squeak that is audible to humans.

If you think about it, wouldn’t it be easier to just poison the cockroaches with the usual means - crayons, gels or boric acid?

Magnetic resonance repeller AR120

The device with the strange name AR120 is declared by the manufacturer as magnetic resonance. This means it is capable of creating low frequency waves, and it is these waves that will torment the cockroaches, create discomfort for them, surviving the insects from your home once and for all.

It is inaudible to the human ear, does not pose any danger to animals, and begins to act almost immediately after switching on. According to the manufacturer, the device will leave absolutely no chance for the small, mustachioed inhabitants, but buyers have a slightly different opinion.

Judging by the reviews, the device really gets rid of cockroaches, but only in the room where it is turned on. Apparently, it's all about the small radius of action.

Advantages and disadvantages of electronic repellers

Positive sides:

• Repellers are easy to use. All you need to do is plug it into a power outlet and follow the instructions supplied with the device by the manufacturer.
• It does not use toxic substances and does not produce annoying noise. After all, the frequency range of its radiation is beyond the capabilities of our hearing organs.
• It can be used multiple times depending on working conditions. After expelling cockroaches from your home, you can let your family or friends use it.
• Unlike cockroaches, you don’t hear anything;
• Safe for the nervous system of people and some households; animals;
• Presented on the market in a large assortment;
• Covers the problem over large areas;
• Long-playing.

Negative sides:

• Your beloved rodents and guinea pigs will suffer;
• Expensive;
• Sometimes emits an unpleasant odor
• Ultrasonic devices do not pass through walls, significantly reducing the radius of sound propagation.
• The device repels cockroaches, but does not kill them.

The principle of operation of repellers: how does the device work on cockroaches?

The device for repelling cockroaches includes a high-frequency pulse generator and a speaker. Does the device really have such a detrimental effect on cockroaches?

If you believe the results of scientific research, the principle is to influence the nervous system of mustachioed pests - the parasites experience discomfort and leave their previous home . Thus, the cockroach repeller does not kill the insect, but only creates an unfavorable environment.

Before you figure out how to install and get rid of cockroaches once and for all, it’s worth taking into account a few recommendations for choosing an ultrasonic device.

Rating of the 12 best repellers

There is high competition among electronic repellers on the market. Some people swear that ultrasonic repellers have worked wonders on their bug problems, while others swear just as vehemently that they did nothing.

Since ultrasonic techniques rely on the propagation of ultrasonic sound waves, we suspect a lot of this has to do with the placement of the devices, interference from upholstered furniture (which absorbs sound), and other physical obstacles.

Russian repeller "GRAD A-1000 PRO"

A universal device that has 4 operating modes (against cockroaches, mosquitoes, low power and high). The range is up to 1000 square meters. The repeller can be used in different rooms (both residential and industrial). The desired result appears within 2 weeks. The device does not overheat.

31st century UP-118

The device is absolutely safe for humans. Pests are leaving their hiding places.

The advantage is the high frequency of the device (30-65 thousand Hz). The sound pressure level reaches 140 dB. It is also convenient that there is a power adapter available. The ultrasonic domestic cockroach repeller covers large areas (230 sq.m.). In addition to cockroaches, you will also get rid of moths, fleas and other parasites.

Tornado OT.02

According to the manufacturer's plan, the device is equipped, because it is known that they are no less afraid of sunlight than ultrasound. The ultrasonic domestic cockroach repeller weighs very little, has small dimensions, temperature control (from -30 to +80 degrees), but, unfortunately, it covers an area of ​​only 50 square meters.

LS-968

The model has a stylish and functional design, in addition, it can be placed on the wall and ceiling. The frequency of ultrasonic waves reaches 27 thousand Hz, sound pressure is 130 dB. Adjusting the temperature of the ultrasonic cockroach repeller from -10 to +50 degrees Celsius

During this time, the device has been constantly improved, and this product is the latest development. In the manufacture of the repeller, high-quality components of Russian and foreign production are used. Each device undergoes a cycle of tests and monitoring of compliance with the stated technical characteristics.

The first signs of insect disappearance are observed after 1-2 weeks of continuous work. Complete disappearance is observed after 3-4 weeks of continuous operation of the device, after which it can be turned on in a cyclic mode: for example, at night, when insect activity increases.

WK-600

The Belgian ultrasonic repeller Weitech WK-600 is a powerful device with nine operating modes for the most effective fight against specific types of rodents and insects, including cockroaches. Provides impact on a large area up to 325 square meters. m. A special algorithm for generating non-repeating signals makes it impossible for pests to get used to the effects. Equipped with two speakers and a regulator of the intensity of emitted ultrasound. In many modes it operates absolutely silently, so it does not interfere with the work and rest of people around you.

Since the Weitech WK-600 can be configured for mixed sonic-ultrasonic and pure ultrasonic radiation, it can be used both at home and in industrial environments. 9 operating modes allow you to select the most optimal frequency and radiation power to repel specific pests. There is a silent operating mode - you can turn off the audio frequency and use exclusively ultrasonic signals (over 20 kHz).

Will save you from almost all pests! It affects not only rodents (mice, rats), but also insects: cockroaches, fleas, moths, spiders, ants, etc. But it is also expensive, about a hundred euros.

Banzai LS927

The Thai ultrasonic domestic cockroach repeller has earned the trust and recognition of many people for its good results. The only drawback of the repeller is that it is not recommended to be placed near pets or near the bed. The sound produced by the device is quite loud and unpleasant.

Zenet XJ-90

The coverage area of ​​this ultrasonic cockroach repeller is 30-40 square meters. The manufacturer offers stylish design and long service life. However, it is important to keep in mind that this device is a modification of the Air Comfort XJ-90, which has already been poorly effective against cockroaches and has earned a bad reputation.

Reviews about the effectiveness of ultrasound against cockroaches

We have been struggling with a cockroach problem at work for several years now. You poison them, call the special services, spend a lot of money - but they don’t care. They disappear from sanitary treatment for a couple of weeks, and then return in full. Our work involves serving people, so it is important for us that people do not shy away from running insects. And it’s scary to bring them home with your things. And so we purchased a device that, it would seem, should, if not get rid of the problem, then at least somehow improve the situation by reducing the number of insects - the Pest Reject ultrasonic repeller. We started using this device, we have been using it for about four months, if not more, but there is no effect at all. Cockroaches live at their usual pace of life - crawl where they usually do, run next to the device, and under it, and even on it. In my opinion, they even liked living in the surge protector where this device was plugged in. It’s scary to take out the device - you already know that a bunch of Prussians are sitting under it. The device does not perform one percent of its function. It's all a scam for money. We are currently testing Dohlox cockroach gel. So far the result is pleasing.

Ultrasonic cockroach repeller MPPF Alex Typhoon LS-500 - Mental trauma for the cat, but the effectiveness remains in question.

Electromagnetic and ultrasonic rodent and insect repeller Riddex Plus Pest Repeller - It turns out there is a way to deal with cockroaches! I live on the fourth floor. The dishes are washed immediately, everything is clean. The garbage bag is closed. And suddenly cockroaches appeared. I started asking neighbors - the same problem. It turns out that they were crawling all the way from the second floor, there is a wonder woman there. Chemical remedies helped, but not much. I bought such a device. I keep it on in the kitchen at night. Or when I leave home for a few days. The cockroaches disappeared in about ten days. Of course, in combination with chemicals. And with conducting preventive and explanatory work with neighbors. This infection can only be overcome together, so that everyone simultaneously takes measures to eliminate it!

I bought it because of cockroaches, as per the instructions they disappeared after 8 weeks of continuous use, and there were a ton of them, now it also saves ants from mosquitoes

I accidentally learned about the existence of such a miracle of modern technology. I don’t even remember how exactly, but it doesn’t matter. The important thing is that this device works and works, I must say, excellently.

With the birth of the baby, we immediately bought an ultrasonic repeller, we have been using it for more than a year, it works effectively and we forgot what insects are in the house, the baby and we sleep peacefully at night, forgetting that a mosquito or a fly might fly in, nothing interferes with our sleep. It is also very convenient; the repeller glows like a flashlight at night, everything is visible and very beautiful, the baby has already grown up and we don’t have to turn on the light at night, thanks to the repeller, the light in the room is not bright, but at the same time everything is visible and the child calmly goes to the potty.

It all started with the fact that we had cockroaches, we couldn’t get them out, nothing helped, no Velcro, no boric acid, nothing at all. And then we saw in an advertisement this, as they called it, “Miracle device”, so we decided to try it, we ordered it, the most important thing was delivered quickly, we gave the money, we paid, after that we put it in the socket and watched what would happen, they wrote that it should take about four weeks before it starts working and the insects run away, the first time I looked, cockroaches began to accumulate and live on it due to its heating, I thought, okay with them, maybe they’ll leave, and when two months passed and they didn’t go anywhere, I I realized that this device is not working, and that it is just a scam. After that, I collected some money and simply called dez. service, after which I live peacefully.

In one of our rented apartments there were cockroaches crawling in swarms in the kitchen and bathroom. There was no room in the room because they didn't eat there. The former neighbors tried everything they could. nothing helped, there was only one option: move out for a month and poison. But no one was going to move out, I decided on this ultrasound machine, bought 2 pieces at once, everyone said that it was nonsense, it wouldn’t help. But after 2 months of intensive operation of the device in the bathroom and kitchen, the cockroaches simply disappeared, completely. No harm to people and animals. The sound is not very pleasant, but you can get used to it in order to get rid of insects.
