Cockroaches are probably eternal, indestructible and multiply at an incredible rate. Most of all, they annoy the residents of old apartment buildings, in which the most motley people can live. Since ancient times, there have been many folk and chemical remedies to combat 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 cockroach repellers are in demand today among gullible buyers, reviews of which, however, are very ambiguous. This is not to say worse.
The principle of operation of ultrasonic repellers
Ultrasound can repel insects, science has proven it, but… The fact of the matter is that there is a big "but". Only those midges and other mosquitoes that communicate with each other using ultrasonic signals can be scared away with ultrasound of a certain frequency. The frequency of a hazard warning signal is simulated and the operation of the device is based on it. When turned oninto the network, it begins to create ultrasonic waves, from which insects scatter or scatter. To whom what is given.
As for cockroaches, firstly, they need to be destroyed, and this cannot be done with ultrasound. Secondly, these insects do not communicate with the help of high frequencies, they do not have such organs. Therefore, reviews on ultrasonic cockroach repellers are mostly negative. Well, they don’t hear mustachioed danger signals, what can you do.
The impact of ultrasound on cockroaches
It is impossible to say that ultrasound does not affect them at all. Works, only high power. But a person also feels such frequencies, and his four-legged pets too.
Experiments show that high-frequency signals of a certain power affect the general condition of the cockroach, disrupt its nervous system, but in a completely unpredictable way. It would be nice to stop breeding, and then the result. But no, the number of insects is declining very slightly.
Therefore, reviews of ultrasonic cockroach repellers are often replete with complaints that pets stop eating and their owners stop sleeping. Most people get headaches all the time.
Sellers of appliances recommend staying as far away as possible from the included repeller, however, they talk about this even when outraged buyers are trying to return harmful goods. And then they continue to sell the most ineffectiveand not harmless to people means of getting rid of cockroaches.
Ultrasonic Repeller Manufacturers
It is clear that the market is filled with similar Chinese-made devices, 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, and in the USA and in 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 repel both insects and rodents from large areas, receive positive feedback. But there is simply no need to buy a device of this class. Cheaper to get by with gel to kill cockroaches.
Universal rodent and insect repellers
The GRAD A-1000 PRO, an innovative professional device manufactured by the Russian Aifo-Technology LLC, can operate in four different modes, two of which repel rodents, another one repels mosquitoes, and one is designed for other insects. "Grad" serves the area up to 1000 sq. m and removes any 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 repelling mosquitoes. But specifically about scaring away cockroaches in the reviews we are not talking. Maybe because the weapon is too serious against them.
Belgian ultrasonic repeller "Weitech WK600"operates in nine modes and serves an area of more than 300 square meters. meters and in a wide emission spectrum of 2-50 kHz. Nobody buys it to fight separately with cockroaches. And the reviews contain little specifics, but users are satisfied with them. I would like to believe that, in addition to mice, mosquitoes and moths, cockroaches also go into the blue distances.
Ultrasonic cockroach repeller "Typhoon LS-500"
Reviews on it are numerous. But they cannot be called positive. No, not so - a pleasant impression is made by the flashing of the light in the initial period of the device. And somewhere out of thirty reviews, only in a tenth of the users were satisfied with the result - the cockroaches left them.
"Typhoon" produced by MNPPF "Alex" is also a universal powerful repellent device for rodents and cockroaches. The manufacturer claims that special studies were carried out, and according to their data, the level of insect disturbance in the area of the device is maximum.
And its action extends within a radius of eighty meters. The ability to install the device at a distance from the outlet is also considered a plus, because it is equipped with a long cord. The instructions state that the operation of the device does not affect pets.
On the Typhoon LS-500 ultrasonic cockroach repeller, reviews claim that cats react painfully to its work, however, they get used to it over time.
Tornado Cockroach Repeller
Another domestic device, more precisely, a series of devices - "Tornado".
An interesting model "Tornado OT.02" differs in that it emits noonly high frequency sound waves, but also light waves. Everyone who has had to deal with cockroaches knows how briskly these insects scatter when the lights turn on at night in the kitchen or bathroom, their main habitats. Maybe that's why this model is less common than other ultrasonic cockroach repellers, reviews.
"Tornado" scares away with light, not ultrasound, but it scares away. And people are less willing to share positive experiences 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 this condition is not met for some reason, then the manufacturer is not to blame for the inefficient operation of the device.
However, there is some hint of optimism in user reviews. Without much confidence, but they say that not immediately, but there are fewer cockroaches, 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 electrical wiring in the room, even hidden, but without knocking down the settings of home equipmentand without interfering. The main thing is to plug it into an outlet as close to the floor as possible.
The main idea contained in this ultrasonic cockroach repeller reviews - "EcoSniper AR-120" does not help to get rid of cockroaches at all. And the spiders, against which the radiated waves must also fight, are also in no hurry to leave their native corners. True, some users speak positively about the silent operation of the device, and someone notes that especially large cockroaches leave, but the young unceremoniously walk right on the device.
And go and understand whether adult insects really have a more shattered nervous system, or they are easier to destroy with a slipper.
Twin Brothers
In online stores, an electromagnetic device Ixus-KY-6182 is sold, the manufacturer of which is modestly silent on the pages of sellers.
On the Ixus ultrasonic cockroach repeller, the reviews do not contain even the slightest positive emotions, and there are few reviews themselves. The device is like two drops of water similar to Eco Spier, the description of its operation and characteristics in the instructions are almost the same, only it costs much less. Since it can only be purchased via the Internet, it is not worth dreaming about the effectiveness of its work.
Zenet XJ-90 and Air Comfort XJ-90 devices are the same twins. In fact, this is one ultrasonic cockroach repeller, reviews of which are the samenegative and harsh. 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 Pest Reject cockroach repeller is made in the USA.
The manufacturer, choking with delight, extols the characteristics of his device with purely American optimism. And the coverage area is large - 220 square meters, and in a week you can already see the results. With such wonderful characteristics, the device is inexpensive. In theory, it should be snapped up like hot cakes and praised at every turn, but there are no reviews for it.
Most likely, because the instruction recommends using traps and gels at the same time during the first week of use. But if there are effective remedies in the form of gels, then why do we need a repeller? In order for cockroaches to develop a stable reflex - where ultrasound of a certain frequency awaits an indispensable and massive death? Then insects from generation to generation will pass on this science and quickly leave the dangerous place when the device is turned on? Maybe so.
Repeller "Banzai LS927"
On the Taiwanese device, to a greater extent than on the Typhoon ultrasonic cockroach repeller, the reviews are positive in terms of the effectiveness of the impact on insects. It is more powerful, and indeed in a month the cockroaches leave the premises. But the manufacturer honestly warns thatradiation is harmful to people and pets.
It turns out a kind of paradox: insects leave the kitchen, it's true, but they go to rooms where the appliance cannot be used due to harmful effects. In this case, why is it needed, you can completely use effective and inexpensive means, for example, low-toxic insecticides.
Do-it-yourself ultrasonic cockroach repeller
In the holy faith in the effectiveness of insect repellent using ultrasound, but at the same time being afraid of 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 a school circle and be able to work with a thin soldering iron in order to assemble the device.
There is a diagram for an ultrasonic cockroach repeller with your own hands and is not uncommon. You don't even need to invent anything. Today, you can easily find diagrams (one of them is presented above for an example), and a list of necessary parts, and a detailed description of why they are needed, and the sequence of work. Radio components are not in short supply, they can be easily bought in specialized stores or on radio markets. You can make a repeller of the desired power and in practice test 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 a homemade product. The device will be either ineffective or dangerous to people. Moreover, its appearance will be far from perfect.
In conclusion
What can be said in conclusion? Effective ultrasonic cockroach repellers do exist. But these are powerful industrial devices, expensive and unsafe for people. There is no point in using them at home. High-power household appliances, like Typhoon or Banzai, work more or less effectively, 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 danger warning, including cockroaches.
