Ultrasonic scarers are rapidly filling the market today. Successfully used against several groups of parasites, they are gaining wide popularity among consumers and are beginning to be used indiscriminately against all pests. Not surprisingly, the ultrasonic emitter from bedbugs today is a very popular thing.
But whether this repeller works in real conditions is a separate question that few people seriously ask before buying.
The principle of the ultrasonic repeller
Initially, ultrasonic repellers were actively and very successfully used in the fight against mosquitoes. The idea of developing such repellents was based on the scientific evidence that mosquitoes actively use hearing to communicate and find a partner to reproduce, and to recognize the threat and ensure security.Such a signal system in the animal world is a common thing.
So, a mosquito, pursued by a predator, makes a squeak during flight, more subtle than, for example, when grooming a female or feeding. Accordingly, other mosquitoes, hearing such an alarming squeak, rapidly fly away from a dangerous place.
Some of the sounds made by insects are within the ultrasound spectrum and are not audible to humans. For mosquitoes, they are a normal communication tool.
This is interesting: in the same way, mosquitoes react to ultrasound, with which the hunting bat “probes” the space. Since mice feed on mosquitoes as well, its ultrasound screams are also an alarming signal for these insects.
Accordingly, creating an effective ultrasonic repeller was a matter of time for engineers. The frequency of the alarming squeak of mosquitoes was measured, after which the device saw the light, capable of generating the sound of the desired height.
And this device really turned out to be effective. But only against mosquitoes. With other unpleasant human neighbors, the situation is quite different.
Why bugs are not afraid of ultrasound?
Bedbugs do not communicate with ultrasonic signals.Bed bugs do not have wings with which they could hum, like mosquitoes, and they lack other tools for generating sounds.
For bed bugs in communication, searching for food and avoiding hazards, smell is more important. It smells they cause clear and unambiguous reactions. To the sounds they are rather indifferent. And to ultrasound - as well. Science has not yet been verified, but it is possible that bugs do not hear it at all. Like, for example, a person does not hear a squeak of a bat.
Therefore, the anti-bed bug ultrasound does not work, and buying an ultrasonic bug bug is the same as simply throwing money away.
To the note: some theorists tried to explain the indifferent attitude of bedbugs to ultrasound by the fact that these insects settle mainly in sofa mattresses and under beds. Say, the ultrasound is absorbed and suppressed by the mattress, and therefore does not reach the bugs.
But recent experiments by American scientists in which bugs were directly affected by ultrasound showed that the presence or absence of ultrasound does not affect the behavior of the parasites. Ultrasound bugs are simply ignored.
Moreover, ultrasound has virtually no effect on the activity of cockroaches and ants. And for the same reason - for these human cohabitants, high-frequency sounds are not alarms.
But rats and mice are sensitive to powerful ultrasound, but there are only a few devices that really help to get rid of them.
Feedback: “In our laboratory, a serious company (I will not call it in order not to advertise) ordered the testing of the maximum number of ultrasonic pest control products.
Allocated money more than the state allocates for the maintenance of the laboratory for six months. We bought rats, bought all the devices that we could find, conducted tests at a special test site.
According to the results, it turned out that out of more than 30 repellents of different brands and manufacturers only 3 turned out to be really effective against rats. Against bedbugs these scarers don't work. The main part of the devices is frank trash, whose sellers use the fact that the public cannot verify its effectiveness before buying ... ”
Nevertheless, the bugs ultrasound continues to be actively advertised and used by unenlightened citizens until the parasites begin to really bother them.And manufacturers of numerous devices use this, actively promoting them, for example, in online stores.
Ultrasonic devices on the market
Ultrasonic devices for bedbugs are produced by Russian, Ukrainian, European and Chinese manufacturers. The most famous and popular of them are the following ...
- EMR-21 - Bulgarian device, has a plug for direct connection to the outlet. According to the manufacturer, it repels almost all insects and rodents, as well as woodlice, spiders and centipedes. The price is 1350 rubles.
Feedback: “We then tried EMR-21. For a couple of nights the bugs did not disturb us, and then it all began again. Maybe they got used to the sound. But not the point. I was killed by what after bullying bugs Karbofos the largest nest was destroyed just under the outlet in which the device was included. In short, this is a one-time thing. Only Karbofos really helped. ”
- Typhoon LS-500 is an ultrasonic device for bed bugs produced in Russia. In it, the developers even introduced a system of constant changes in the frequency of the sound so that the parasites did not have time to get used to it. The price of the device - 900 rubles.
- Eco-Sniper 9B LS-989 - also a Russian development, judging by the reviews - absolutely ineffective. Price - 1350 rubles.
Reviewed: “Eco-Sniper - Wasted Money. Unscrupulous manufacturers produce unnecessary junk and earn on other people's problems. Bought for children in the hostel. Ordered over the Internet.
We are not alarmed by the fact that according to the instructions, he scares everyone away - bedbugs, mice, and rats. As if they all fear the same sounds. The remedy did not give any result. I had to buy poisons and poison along with my neighbors. Do not buy these devices, they do not work, but they are expensive. Only throw out money. ”
- UP-116T - positioned as a repeller only crawling insects. According to the manufacturers, it realizes the possibility not only of ultrasonic scaring, but also of magnetic resonance effects on bugs. The effect of the latter does not exceed that of ultrasound. The price of the funds - 1850 rubles.
- AR-130 Smart-Sensor, Chinese Ultrasound insect repellent. It works the same way as most analogs. According to Chinese tradition, it costs the least - when ordering online, you can find offers for $ 10.
The average price of an ultrasonic repeller today is 1200-1300 rubles. For the same money, you can buy 20 bottles of the proven “Executor” parasite insect repellent, with the help of which the bugs will be literally destroyed, and with the right approach they will never return.
Therefore, if insects begin to be really disturbing, you should immediately stop all experiments with ultrasound and begin to take serious and more effective methods of struggle.

Reading it all, it just becomes interesting, and who generally consults before buying with the specialists selling these devices (I agree that there are few such specialists). In order for the instruments to perform their tasks, i.e. drove out pests, many factors affect, ranging from choosing a device for each individual case, the required number of devices, their combination, when to turn on the devices and when they should be turned off, and ending with their proper installation.
That's just the right installation of devices and is the foundation. Our company has been selling scarers, traps, etc. for the past 5 years. During this time, we selected decent manufacturers of devices, and the sale of the device always begins with the question: “Who cares about you, where the pests come from,an approximate diagram of your home "and some other questions, and only then we advise the devices. And for all this time, believe me, not a single return and complaints. On the contrary, the recommendations, as they say, on word of mouth.
So, if you are ready to spend money on devices not in vain - just get advice and listen to the recommendations of experts.
Ha. Let's agree on this: come, fix the bedbugs, install and leave. In a week, you will come and see if it helps, then I will cry, and if not, then NO. Agreed?
Well said, but no one will go. And under the contract "free warranty for 1-2-3 years," also have their mulk. We will come to you, but pay for the drugs ... The cost is 50 percent of the contract and at least a thousand rubles.
Contact better in SES of the area. And it's better to rummage around in the internet, buy it yourself and process it.
In the world, rodents, termites, bugs and other miscellaneous destroy up to 40% of food stocks, both during storage and in the fields. This is the greatest problem. Imagine the loss in dollars? And if the ultrasound somehow helped against pests, then there would be generators in each warehouse.Attempts to pair the unsuspecting customers of the miraculous generators have been going on with varying success for 50 years now. And no device has yet shown the stated characteristics.
All sold scares - just a hoax, flavored with pseudo-scientific chatter.
Ultra repellers - it's just a hoax and garbage, until you are treated with Geth, and after Reid from bugs. Could return this piece to the store, but the red tape with sending more, that's lying ...
Ultraparager does not help.
Thanks for all the advice. I'll try to hang the plants (wormwood, tansy, calamus, you can chamomile). If it does not help, I’m looking for a rented apartment more decently)
What will help from bedbugs? We got it.
Slippers - tested by time. Slap - and no bug. Have a buggy safari.
I rubbed finely the garlic, insisted in vinegar for a day, added chalk - it turned out to be a paste. The bugs are gone, and the smell has gone through the week. Two years no bugs.
Excuse me, but in what proportions did you make the remedy?
