Ultrasonic repellents of cockroaches: reviews and description

Cockroaches, probably, are eternal, ineradicable and breed with incredible speed. Most of all they annoy tenants of apartment buildings of old construction, in which the most diverse people can live. There have long been a lot of folk and chemical remedies against these ubiquitous insects, but almost all of them are dangerous for humans and domestic animals. They need to be constantly updated, and cockroaches get used to them. Therefore, ultrasonic repellents of cockroaches are in demand among trusting customers today, but the reviews are very ambiguous. This is not to say worse.

Principle of operation of ultrasonic repellers

Ultrasound can scare off insects, science has proven this, but ... The fact of the matter is that there is a great "but". Scare off ultrasound of a certain frequency can only be those midges and other mosquitoes that communicate with each other using ultrasonic signals. The frequency of the warning signal is simulated, the operation of the instrument is based on it. When switched on, he begins to create ultrasonic waves, from which the insects fly off or scatter. To whom that is given.

As for cockroaches, first, they must be destroyed, and ultrasound can not be done. Secondly, with the help of high frequencies these insects do not communicate, they do not have such organs. Therefore, the ultrasound repellents of cockroaches reviews are mostly negative. Well, do not hear the mustachioed signals about the danger, what can you do about it.

The effect of ultrasound on cockroaches

To say that ultrasound does not act on them at all is impossible. Acts only high power. But such a frequency a person also feels, and his four-legged favorites too.

Experiments show that high-frequency signals of a certain power affect the overall state of the cockroach, disturb its nervous system, but in an unpredictable manner. It would be okay to multiply, and that's the result. But no, the number of insects is reduced very slightly.

Therefore, reviews of ultrasound cockroaches often abound with complaints that pets stop eating, and their owners - to sleep. Most people have a headache all the time.

Vendors of the same devices recommend to be kept from the included repeller as far as possible, however, they say this already when indignant buyers try to return the harmful goods. And then they continue to sell the most inefficient and harmless for people means of getting rid of cockroaches.

Manufacturers of ultrasonic repellers

It is clear that the market is filled with similar instruments of Chinese production, and the attitude towards them is negative, rather, not from lack of effect, but from traditional rejection of the quality of goods from China.

But the ultrasonic scarecrows of cockroaches, the reviews on which do not radiate friendliness, are produced both in Taiwan, and in the USA and in Russia, and the enterprises whose products are effective enough 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, are awarded positive reviews. But there is simply no need to buy a device of this class. It is cheaper to dispense with gel for the destruction of cockroaches.

Universal scarer and insect repellers

The innovative professional device manufactured by the Russian LLC "Aifo-Technology" "GRAD A-1000 PRO" can operate in four different modes, two of which repels rodents, another one - mosquitoes, and one is for other insects. "Grad" serves an area of up to 1000 square meters. M and removes all pests for two weeks of permanent work. But its main purpose - the fight against rodents. And with this task, he is doing fine. Also good reviews about mosquito repellent. But it's specifically about scaring away cockroaches in the reviews it does not go. Maybe because it's too serious a weapon 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 spectrum of radiation 2-50 kHz. Nobody buys it for fighting alone with cockroaches. And the specifics of the content contain little, but users are happy with it. I want to believe that, in addition to mice, mosquitoes and moths, the cockroaches go to blue distances.

Ultrasonic repeller of cockroaches "Typhoon LS-500"

There are numerous reviews. But they can not be called positive. No, not so - a pleasant impression produces a blinking light in the initial period of the device. And somewhere from thirty reviews only in the tenth part users were satisfied with the result - the cockroaches left them.

"Typhoon" produced by MNPF "Alex" is also a universal powerful repellent rodents and cockroaches device. The manufacturer claims that special studies were conducted, and according to their data, the level of insect anxiety is maximum in the range of the device.

And its action extends within a radius of eighty meters. Plus, it is also possible to install the device at a distance from the outlet, because it is equipped with a long cord. The instruction states that the operation of the device does not affect domestic animals.

On ultrasound repeller cockroaches "Typhoon LS-500" reviews claim that cats react to his work painfully, however, eventually get used to.

Tornado cockroach repeller

Another domestic device, more precisely, a series of instruments - "Tornado".

An interesting model of the "Tornado OT. 02" differs in that it emits not only high frequency sound waves, but also light waves. Everyone who has had to deal with cockroaches knows how quickly these insects flutter when night lights turn on in the kitchen or bathroom, the main places of their dwelling. Maybe that's why this model is less common than other ultrasound cockroaches, reviews.

"Tornado" scares away light, not ultrasound, but scares off. And positive impressions people share less willingly than negative.

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 hanging closets in the kitchen, but also at some angle to the vertical. That is, if this condition is not maintained for some reason, the manufacturer is not to blame for the inefficient operation of the device.

However, some note of optimism in the feedback of users is present. Without special confidence, but it is said in them that not immediately, but the cockroaches become smaller, although they do not go away at all.

Repeller of cockroaches "EkoSniper AR-120"

This device manufactured by Hong Kong is magnetic resonance and emits low-frequency waves, which are destructive to affect the nervous system of cockroaches, so insects must leave their places of origin. According to the manufacturer, the radiation is transmitted through wiring in a room, even hidden, but without knocking down the settings of the home equipment and creating no interference. The main thing is to plug it into the socket as close to the floor as possible.

The main idea contained in this ultrasound cockroach repeller is "Eco Sniper AR-120" does not help at all to get rid of cockroaches. And spiders, against which the radiated waves must also fight, also do not hurry to leave their native corners. However, some users respond positively to the silent operation of the device, and someone notes that especially large cockroaches leave, but the youngsters unceremoniously walk straight on the device.

And go to understand whether it really is in adult insects the nervous system is weakened, or it is easier to destroy them with a slipper.

"Gemini brothers"

The online store sells an electromagnetic device Ixus-KY-6182, the manufacturer of which on the pages of sellers modestly silent.

At the ultrasound repeller cockroaches Ixus reviews do not contain even the slightest positive emotions, and the reviews themselves are few. The device as two drops of water is similar to the "Eco Spyer", the description of its operation and the characteristics in the instructions are practically the same, but it costs considerably less. Since it can only be purchased via the Internet, it is also not worth dreaming about the effectiveness of its work.

The same twins are the Zenet XJ-90 and Air Comfort XJ-90. In fact, this is one repeller of cockroaches ultrasonic, reviews on which are equally negative and cutting. They emphasize that the new name did not affect the effectiveness of the previously tested and completely discredited device.

Pest Reject cockroach repeller

The electronic ultrasonic repeller of cockroaches Pest Reject is produced in the USA.

The manufacturer, choking with delight, with purely American optimism extols the characteristics of its device. And the coverage area is large - 220 square meters, and a week later you can see the results. With such remarkable characteristics, the device is inexpensive. In theory, it should snap like hot pies, and praise at every turn, but there is no feedback on 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 agents in the form of gels, then why do we need a deterrent? So that the cockroaches developed a persistent reflex - where ultrasound of a certain frequency, is expected an indispensable and mass death? Then will insects from generation to generation transmit this science and quickly leave a dangerous place when the device is turned on? May be so.

Repeller "Banzai LS927"

On the Taiwanese device to a greater extent than the ultrasound repeller cockroaches "Typhoon" reviews are positive in terms of the effectiveness of exposure to insects. It is more powerful, and really in a month from the room the cockroaches leave. But the manufacturer honestly warns that radiation is harmful to humans and pets.

It turns out a kind of paradox: from the kitchen, the insects leave, it's true, but they leave to the rooms, where the device can not be used due to harmful effects. In this case, why it is needed, you can fully use effective and inexpensive means, for example, low-toxic insecticides.

Ultrasonic repeller cockroaches with your own hands

In the holy belief in the effectiveness of repelling insects with the help of ultrasound, but at the same time fearing fakes, you can make the device with your own hands. True, this work is not for everyone. It is necessary 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 the ultrasonic repeller cockroaches own scheme is available and is not uncommon. You do not even need to invent anything. Today, without any problems, one can find schemes (one of them is presented above for example), and a list of necessary details, and a detailed description of what they are needed for, and the sequence of work. Radio components are not a deficit, they can be easily bought 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 disappear in home-made clothes. The device will be either inefficient or dangerous for people. Moreover, his appearance will be far from perfect.

Finally

What can we say in conclusion? Effective ultrasonic scares of cockroaches nevertheless exist. But these are powerful industrial devices, expensive and unsafe for people. At home they do not make sense. More or less effective household appliances of high power, like "Typhoon" or "Banzai", but they are harmful to humans and their pets. And not harmful devices are safe for all living, not perceiving ultrasonic signals as a warning of danger, including cockroaches.
