How does ultrasound from bedbugs work?
The idea of repelling insects with a device that emits sound waves found a lively response among the population. Agree, it is tempting to include a small appliance in the network and enjoy a relaxing holiday all night. After all, similar devices against mosquitoes work, why then ultrasound from bugs can not help?
The principle on which the operation of an ultrasonic device is based
To find out if ultrasound helps from bugs, consider the principle of its action. The idea of an ultrasonic repeller is based on serious scientific research. So, for example, it was found that many insects are able to hear sound waves of a certain frequency. However, some sounds can inspire them with a sense of anxiety and horror.
The first mosquito repellent device was built. And it really worked! Flying bloodsuckers rushed to leave the ultrasound area. Then they started talking about the universality of the device and began to use it not only against mosquitoes, but also against bugs, cockroaches, mice and rats.
Does a repeller help against bedbugs?
So, ultrasound really scares away mosquitoes. But does he act in a similar way on bedbugs? Let's figure it out.
In the process of laboratory experiments, it was found that bugs, unlike mosquitoes, do not communicate using ultrasound. The main channel of their perception of the world is the sense of smell and touch. Therefore, they are absolutely indifferent to sound waves, as was proved by recent experiments of American scientists. They targeted insects with sounds of different frequencies and did not notice absolutely no changes in their behavior. Even the hypothesis was put forward that they did not hear ultrasound at all, which until now has not been refuted by anyone.
So, we found out that the bug repeller is a myth. An ultrasonic device does not work against this type of insect. But what about the many rave reviews on the Internet? It can’t be that they are all fake? Perhaps this is true, or maybe just the result of a coincidence and the delayed action of a previously used insecticide.
Overview of the most popular appliances
Despite the proven inefficiency of ultrasound devices, they still go on sale and they, in spite of everything, are still being bought up. Maybe some of them really work and an effective bug repeller is still a reality? Let's look at the most popular models of devices.
Eco sniper
Eco-sniper is produced by a Russian company. According to the developers, he is able to scare away not only bugs, but even mice and rats. Such a device is relatively expensive, about 1400 rubles.
Reviews of people who used it are mostly negative. As expected, he did not live up to their expectations and could not cope with his work.
Typhoon
Another development of Russian manufacturers. The developers went further in their research and improved the device with a system that changes the frequency of the waves from time to time. Similarly, they ensured that ultrasound was not addictive in insects. Allegedly it is this that is the reason for the inefficiency of previous repellers.
Unfortunately, even such an improvement did not help against bedbugs. Customer reviews indicate the absence of any effect from the device. It costs a little less than an eco-sniper, about a thousand rubles.
Emr-21
It is produced by a Bulgarian company and is designed to repel bugs, mice, rats, spiders, as well as other insects. It costs about the same as the Eco-sniper, about 1300-1500 rubles.
Amused this review about the action of this miracle device:
“At first he seemed to act, but soon the insects returned and continued to live, as if nothing had happened. With the subsequent disinfestation, it turned out that the largest accumulation of insects was observed just in the outlet where the device was connected! ”
Smart sensor
The device is made in China. It has a more than affordable price. It costs only 600 rubles. but also promises quick disposal of insects. It is hard to believe in this, and not only the low cost of the product, but the general principle of its work, which is no different from other repellers, raises doubts.
Reviews about the effectiveness of the device did not add faith in a miracle. He, like other ultrasonic devices, does not act against bugs.
