Ultrasonic bug bugs

Thirty years ago, city dwellers stopped meeting bugs in their apartments. But in the last decade the frequency of occurrence bed bugs increased by 10%. Scientists have attributed the growth of the blood-sucking parasite population to the emergence of insect-resistant insects. New means of combating synanthropic pests, including the ultrasonic bug repeller, are being created.

Principle of operation of the device

An ultrasonic device from bedbugs produces sound in the inaudible range for humans. Modern industry puts on the market a mass of ultrasonic devices with different characteristics. Ultrasound has a low frequency of the wave, compared with sounds in the audible range. It obeys the same physical laws, but audible and ultrasound have different effects on the environment. Ultrasound has long been successfully used in biology, medicine, physics, chemistry.

Ultrasound is reproduced using a piezo emitter. Repellers can work from different power sources - batteries or sockets. The higher the voltage applied to the generator, the more effective the operation of the device. Through the speaker, the sound acts on the air, creating elastic vibrations. They are distributed in the air and can not overcome the dense environment - walls, furniture.

Ultrasonic Repeller

Devices have a device that changes the wavelength. Electronic bug repeller can change the frequency of ultrasound in automatic mode or manual tuning.

The bugs ultrasound device does not destroy insects, but creates an irritant effect thataccording to the manufacturers, scares them. The effectiveness of the effect of the repeller is not proven by scientific studies. In publications there are single mentions of private research on small samples that have no scientific value.

In 2002, Kansas State University conducted research on the effectiveness of an ultrasonic repeller for dogs, rats, mice, flying and crawling insects. It was found that dogs and rodents respond to ultrasound. He worries them, causes panic and leads to flight. In relation to insects, the effect was not unambiguous. The apparatus had the most pronounced effect on crickets, mosquitoes, and flies. Controversial results were obtained for bedbugs and cockroaches.

Therefore, reviews of ultrasonic repellers bugs are different. To understand why this is possible, if we consider the physiology of the bug.

The impact of ultrasound on bedbugs

The main argument, according to which the ultrasound from the bugs is not effective, is that this type of insect has no organs that emit sound, and therefore they have no organs of hearing.But scientists still do not come to a common opinion - whether bugs make sounds. After all, not only the fluttering of wings or the friction of a leg on a leg can be a source of sound in insects.

Bed bugs

Bedbugs on the legs and abdomen are sensitive hairs associated with nerve endings. With the help of sensible insects feel the heat radiation, vibrations of the air. The organs of hearing have not been found in bugs, but a high sensitivity to odors and temperature makes it possible to find food and a sexual partner.

Bacteria and viruses also have no organs of hearing, but ultrasound, thanks to the effect of cavitation, successfully fights them. It is used to sterilize products, medical instruments, drinking water. Under the action of ultrasound, bubbles appear in biological fluids, which increase in size with prolonged acoustic exposure. Bursting bubbles create shock and thermal effects, destroying the tissues of living organisms. The parasite does not need to listen to ultrasound in order to feel the discomfort from scaring with the help of ultrasonic waves.

The lower the ultrasound frequency, the easier it is to get cavitation and the more aggressive its effect on living organisms. Therefore, many devices use a frequency of 20-22kHz. Whether ultrasound helps from bedbugs can not be said for sure, since studies have not confirmed the effectiveness of the repellents. But the synergistic effects of ultrasound and insecticides have been studied.

Ultrasound means creates cavitation in the body of the parasite, which increases its sensitivity to insecticides. Bed bugs ultrasound together with insecticides are effective even against resistant insects. The combined effect, which has synergistic properties, manifests itself even when using an electromagnetic bug repeller. In it, the action of ultrasound is combined with magnetic radiation, enhancing the effectiveness of each other.

Overview of popular scarers

Ultrasonic Repeller

On the market now there are many ultrasonic repellents, both professional and semi-professional. To choose the most effective device, you need to study its characteristics. The most popular and advertised are:

• EMR-21 - Ultrasonic bug repeater, manufactured in Bulgaria.The device works from the network. The manufacturer guarantees that when using it after 4 weeks the parasites will disappear from the house. With a strong infection, you need to extend the effect of the ultrasonic repeller for another 4 weeks. The device generates ultrasound and the bugs disappear from the house. The price of the device - 1100 p.
• Typhoon LS-500 - domestic product based on the effects of ultrasound on insects. The advantage of an ultrasonic repeller is the presence of an automatic frequency switch that prevents insects from getting used to waves of a certain frequency. Price - 1100 p.
• Eco Sniper ls 919 - has a high degree of coverage. One device can act on the area of ​​180-200 m². Also has a frequency switch. The manufacturer (Taiwan) claims that within 2-6 weeks the bugs leave the apartment. The price of the device - 660 p.
• Tornado Beat FP-003 - New development in the market of ultrasonic repellers. In addition to the ultrasonic device generates electromagnetic waves that penetrate into the thickness of the walls, spreading through the wiring, expelling bugs from sockets, electrical panels, household appliances. It can be used both on an industrial scale and in apartments.The manufacturer claims that the device does not affect the operation of electrical appliances, mobile phones, the human body.
• Pest Redjekt bug bugs It combines ultrasonic and electromagnetic effects, so manufacturers place special hopes on the device. The coverage area is 200 m2, which makes it possible to limit one device for the treatment of a room from bugs. The price of the device is 2000 p. You can order the device through the online store.

Pest reject

Electronic tools have different efficiencies, which depend not only on the characteristics of the device, but also on the manufacturer.

Like many advertised insect repellents, the cost of which is quite high, ultrasonic repellents have many fakes. Counterfeit is somewhat cheaper than the original and is not able to destroy insects, as it generates waves of insufficient power. When buying a repeller, you must make sure that the purchased device is not a fake.

Many devices are similar in appearance to the adapter, which is enough to insert into the outlet to get started. The loudness of the sound during operation is minimal, but some reviews contain complaints about the fact that the device beeps.In order for the protection of the house to be complete, you need to choose the right place to install the device, set the volume in order to ensure complete destruction of insects and to withstand the time specified in the instructions for which the ultrasound will be issued.

You can buy the device in stores of large cities such as Moscow or order it online. Delivery is made in the most remote settlements of the country. The ultrasonic defender has different reviews that can be found on the forums.

Reviews

Have bought Ultrasonic repeller Pest repeller from bedbugssince we live in a private house and insects, mice and rats simply do not allow to live. Chose a repeller, watching ads on TV. Not to say that they were completely disappointed - the rats and mice disappeared, but nothing happened with the insects. In the couch bedbugs both nested and remained in it.

I had bugs after a trip to a holiday home. Tried to withdraw folk remedies, so as not to poison yourself with poisons. They began to bother a little less, but after a while they appeared again. I decided to buy an ultrasonic repeller. I bought via the Internet AR-130 Smart-Sensor.He did not give anything, although I used it according to the instructions. But when applied Reid facilitythen the bugs are gone. And it took the drug less than it was written. This means that the device has brought some benefit, although not the one I hoped for.

Acquired Tornado Strike FP-003. Heard a lot about him from friends. The device looks pretty, consumes a little electricity, it works silently. Initially, the mice disappeared, which gnawed under the floor. Then cockroaches fled. I had to tinker with the bloodsuckers, but in the end get rid of bedbugs also succeeded. I do not know for how long, but until the unit is turned off. Let him work more.

I want to share my experience on using the Ekosniper ls 919 ultrasonic repeller. I bought it from home bugs, which simply tortured the whole family. Insects to us crawled from neighbors. Caused Professional Pest Control Service. The respite was only 4 months, and then it all began again. I did not like the fact that the smell after disinsection lasted a long time. Therefore, I decided to buy a repeller. so as not to breathe chemistry. The device has been working for a month, but there is no sense. I'll wait for more.If there is no effect, you will have to look effective remedies for bedbugs and poison chemistry.
