Cockroaches are probably eternal, indestructible and breed with incredible speed. Most of all they annoy the residents of old-built apartment buildings in which the most motley people can live. Since ancient times, there are many folk and chemical means of combating these ubiquitous insects, but almost all of them are dangerous for people and pets.
They need to be constantly updated, and cockroaches get used to them. Therefore, ultrasonic
repellents of cockroaches are in demand today among gullible customers
, reviews for which, however, are very mixed. This is not to say worse.
The principle of operation of ultrasonic repellers
Ultrasound can scare insects, it is proved by science, but ... The fact of the matter is that there is a big "but." It is possible to scare away by ultrasound of a certain frequency only those midges and other mosquitoes that communicate with each other using ultrasonic signals. The frequency of the hazard warning signal is simulated; the operation of the device is based on it. When connected to the network, it begins to create ultrasonic waves, from which insects scatter or scatter. To whom is given.
As for cockroaches, then, firstly, they need to be destroyed, but this cannot be done with ultrasound. Secondly, with the help of high frequencies, these insects do not communicate, they do not have such organs. Therefore, reviews on ultrasonic cockroach repellers are mostly negative. Well, the mustachioed signals of danger do not hear what can be done.
The impact of ultrasound on cockroaches
It is impossible to say that ultrasound does not affect them at all. Valid only high power. But man also feels such frequencies, and his four-legged favorites, too.
Experiments show that high-frequency signals of a certain power affect the general condition of a cockroach, disrupt its nervous system, but in an absolutely unpredictable way. It would be nice to stop multiplying, and then the result. But no, the number of insects is reduced very slightly.
Therefore, reviews on ultrasonic cockroach repellers are often replete with complaints that pets stop eating and their owners sleep. Most people have a headache all the time.
Sellers of devices recommend that they be as far from the included repeller as possible, however, they talk about this even when outraged buyers try to return harmful goods. And then they continue to sell the most ineffective and harmless to people means of getting rid of cockroaches.
Ultrasonic Repeller Manufacturers
It is clear that the market is filled with similar devices made in China, and the attitude towards them is negative, rather, not from the lack of effect, but from the traditional rejection of the quality of goods from the Middle Kingdom.
But ultrasonic cockroach repellers, reviews of which do not radiate friendliness, are produced in Taiwan, the USA and Russia, and enterprises whose products are quite effective in the fight against rodents, bats and mosquitoes.
Powerful expensive devices, as a rule, are universal and designed to scare away insects and rodents from large areas, they receive positive reviews. But there’s no reason to buy a device of this class. Cheaper gel for the destruction of cockroaches.
Universal repellents of rodents and insects
The innovative professional device manufactured by the Russian LLC Aifo-Technology GRAD A-1000 PRO can operate in four different modes, on two of which it repels rodents, on another mosquito, and another is designed for other insects. Grad serves an area of up to 1000 square meters. m and removes all sorts of pests in two weeks of constant work. But its main purpose is the fight against rodents. And he copes with this task perfectly. Also good reviews on mosquito repellent. But specifically about the repellent of cockroaches in the reviews we are not talking about. Maybe because the weapons are too serious against them.
The Belgian ultrasonic repeller Weitech WK600 operates in nine modes and serves an area of more than 300 square meters. meters and in a wide spectrum of radiation of 2-50 kHz. Nobody buys it to fight separately with cockroaches. And the specifics of the reviews contain a little, but users are satisfied with it. I would like to believe that, in addition to mice, mosquitoes and moths, cockroaches also go to blue distances.
Ultrasonic cockroach repeller "Typhoon LS-500"
Reviews on it are numerous. But they cannot be called positive. No, not like that - a blinking light makes a good impression during the initial period of operation of the device. And somewhere out of thirty reviews in only a tenth of the users were satisfied with the result - cockroaches left them.
"Typhoon" manufactured by MNPF "Alex" is also a universal powerful device that repels rodents and cockroaches. The manufacturer claims that special studies were carried out, and according to their data, the level of insect anxiety in the zone of the device is maximum.
And its action extends within a radius of eighty meters. A plus is the ability to install the device at a distance from the outlet, because it is equipped with a long cord. The instructions state that the appliance does not affect pets.
On the ultrasonic cockroach repeller “Typhoon LS-500”, reviews say that cats react painfully to his work, though they get used to it over time.
Cockroach repeller "Tornado"
Another domestic device, or rather, a series of devices - "Tornado".
An interesting model “Tornado OT.02” is different in that it emits not only high-frequency sound waves, but also light waves. Everyone who had to deal with cockroaches knows how quickly these insects scatter when the lights in the kitchen or bathroom, the main places they live, turn on at night. Maybe that's why this model is less common than other ultrasonic cockroach repellers, reviews.
"Tornado" scares away light, not ultrasound, but it scares away. And people share positive impressions less readily than negative ones.
What is especially interesting in using the Tornado OT.02 device is that it needs to be installed in a special way. Not only at a certain height, slightly above the work surfaces, but under the wall cabinets in the kitchen, but also at a certain angle to the vertical. That is, if for some reason this condition is not met, the manufacturer is not to blame for the inefficient operation of the device.
However, some note of optimism in user reviews is present. Without much confidence, but they say that it’s not immediately, but the cockroaches become smaller, although they do not go away at all.
Cockroach repeller "EcoSniper AR-120"
This Hong Kong-made device is magnetic resonance and emits low-frequency waves, which are designed to have a detrimental effect on the nervous system of cockroaches, so insects must leave their homes. According to the manufacturer, the radiation is transmitted through the wiring in the room, even hidden, but without knocking down the settings of the home equipment and without interfering. The main thing is to plug it in as close to the floor as possible.
The main idea that reviews contain on this ultrasonic cockroach repeller is that EcoSniper AR-120 does not help to get rid of cockroaches at all. And the spiders, against which the emitted waves must also fight, are also in no hurry to leave their native corners. True, some users respond positively to the noiseless operation of the device, and someone notes that especially large cockroach individuals leave, but the young growth unceremoniously walks right around the device.
And go understand, whether the nervous system is really shaken in adult insects, or it is easier to destroy them with a slipper.
“Twin brothers”
In online stores, the electromagnetic device Ixus-KY-6182 is sold, the manufacturer of which is modestly silent on the pages of sellers.
On the ultrasonic cockroach repeller Ixus, the reviews do not contain even the slightest positive emotions, and the reviews themselves are few. The device, like two drops of water, is similar to the Eco Spyer, the description of its operation and characteristics in the instructions are practically the same, only it costs much cheaper. Since you can only purchase it via the Internet, you should not even dream about the effectiveness of its work.
The twins are Zenet XJ-90 and Air Comfort XJ-90. In fact, this is one ultrasonic cockroach repeller, reviews for which are equally negative and cutting. They emphasize that the new name did not affect the efficiency of the previously tested and completely discredited device.
Cockroach Repeller Pest Reject
The electronic ultrasonic cockroach repeller Pest Reject is made in the USA.
The manufacturer, choking with delight, with purely American optimism extols the characteristics of his device. And the coverage area is large - 220 square meters, and after a week you can already see the results. With such wonderful characteristics, the device is inexpensive. In theory, they should grab him like hotcakes and praise him at every step, but there are no reviews for him.
Most likely, because the instruction recommends the use of traps and gels at the same time during the first week of use. But if there are effective agents in the form of gels, then why is a repeller needed? In order for cockroaches to develop a stable reflex - where there is an ultrasound of a certain frequency, an indispensable and massive death awaits? Then insects from generation to generation will transmit this science and quickly leave a dangerous place when you turn on the device? May be so.
Repeller "Banzai LS927"
On the Taiwanese device to a greater extent than on the ultrasonic cockroach repeller "Typhoon" reviews are positive in terms of the effectiveness of exposure to insects. It is more powerful, and indeed a month later the cockroaches leave the premises. But the manufacturer honestly warns that radiation is harmful to people and pets.
It turns out a paradox: insects leave the kitchen, it’s true, but go to rooms where the device cannot be used due to harmful effects. In this case, why is it needed, you can quite take advantage of effective and inexpensive means, for example, low-toxic insecticides.
DIY Ultrasonic Cockroach Repeller
In the holy faith in the effectiveness of repelling insects using ultrasound, but at the same time fearing fakes, you can make a device with your own hands. True, this work is not for everyone. You need to understand radio engineering at least at the level of the school circle and be able to work with a thin soldering iron to assemble the device.
On an ultrasonic cockroach repeller, a do-it-yourself circuit is available and is not uncommon. You don’t even have to invent anything. Today, without problems, you can find schemes (one of them is presented above as an example), and a list of necessary details, and a detailed description of why they are needed, and the sequence of work. Radio components are not in short supply; you can safely buy them in specialized stores or on radio markets. You can make a repeller of the desired power and in practice check its effectiveness for little money, while enjoying your own creativity.
But the trouble is that the shortcomings of industrial devices will not go anywhere in homemade products. The device will be either ineffective or dangerous for people. Moreover, his appearance will be far from perfect.
Finally
What can be said in conclusion? Effective ultrasonic cockroach repellers do exist. But these are powerful industrial devices, expensive and unsafe for people. At home, it makes no sense to use them. More or less efficient household appliances of high power, such as “Typhoon” or “Banzai,” work, but they are harmful to humans and their pets. And non-harmful devices are safe for all living things that do not perceive ultrasonic signals as a warning of danger, including cockroaches.
