Ultrasonic bug repellers

30 years ago, urban residents stopped meeting bugs in their apartments. But in the last decade, the frequency of occurrence bed bugs increased by 10%. Scientists attribute the growth of the bloodsucking parasite population to the emergence of insecticide-resistant insects. New means of combating synanthropic pests are created, among which are the ultrasonic bug repeller.

The principle of operation of the device

The ultrasonic device from bugs produces sound in a range inaudible to humans. Modern industry markets a ton of ultrasound devices with different characteristics. Ultrasound has a low wave frequency, 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 supplied to the generator, the more effective the device. Through the speaker, sound acts on the air, creating elastic vibrations. They spread in the air and cannot overcome dense environments - walls, furniture.

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

The ultrasonic device from bugs does not destroy insects, but creates an irritating effect, which, according to the manufacturers, repels them. The effectiveness of the impact of the repeller is not proven by scientific research. In publications, there are isolated references to private research in small samples that do not have scientific significance.

Interesting!

In 2002, Kansas State University conducted research on the effectiveness of an ultrasonic repeller against dogs, rats, mice, flying and crawling insects. It has been found that dogs and rodents respond to ultrasound. He leads them into anxiety, cause panic and take to flight. With respect to insects, the effect was ambiguous. The apparatus had the most pronounced effect on crickets, mosquitoes, and flies. Controversial results were obtained regarding bugs and cockroaches.

Therefore, reviews about ultrasonic bug repellers are different. You can understand why this happens if you consider the physiology of the bug.

The impact of ultrasound on bedbugs

The main argument that ultrasound from bugs is not effective is that this type of insect does not have organs that make a sound, and therefore they do not have hearing organs. But scientists still have not come to a consensus - do bugs make sounds. After all, not only the flutter of the wings or the friction of the leg against the leg can serve as a source of sound in insects.

In bedbugs, legs and abdomen have sensitive hairs associated with nerve endings. With the help of sensilla, insects feel heat radiation, air vibrations.Hearing organs were not found in bedbugs, but their high sensitivity to smells and temperature allows finding food and a sexual partner.

Bacteria and viruses also do not have hearing organs, but ultrasound, thanks to the effect of cavitation, successfully fights them. It is used to sterilize products, medical instruments, and drinking water. Under the action of ultrasound in biological fluids, bubbles arise, which with prolonged sound exposure increase in size. Bursting, the bubbles have a shock and thermal effect, destroying the tissues of living organisms. The parasite does not have to listen to ultrasound at all in order to feel the discomfort of scaring away with the help of ultrasonic waves.

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

An ultrasonic agent creates cavitation in the body of the parasite, which increases its sensitivity to insecticides. Bedbug ultrasound combined with insecticides are effective even against resistant insects. The combined effect, which has synergistic properties, is also manifested when an electromagnetic bug repeller is used. In it, the action of ultrasound is combined with magnetic radiation, enhancing each other's effectiveness.

Overview of popular repellers

There are many ultrasonic repellers on the market now, 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 repeller manufactured in Bulgaria. The device works from a network. The manufacturer guarantees that when used after 4 weeks, the parasites will disappear from the house. With severe infection, you need to extend the effect of the ultrasonic repeller for another 4 weeks. The device generates ultrasound and bugs disappear from the house. The price of the device is 1100 r.
• Typhoon LS-500 - a domestic product based on the effects of ultrasound on insects. The advantage of an ultrasonic repeller is the presence of an automatic frequency switch, which prevents insects from getting used to waves of a certain frequency. Price - 1100 p.
• EcoSniper ls 919 - has a high degree of coverage. One device can operate on an area of ​​180-200 m². Also has a frequency switch. The manufacturer (Taiwan) claims that within 2-6 weeks, bedbugs leave the apartment. The price of the device is 660 p.
• Tornado Punch FP-003 - A new development in the market of ultrasonic repellers. In addition to ultrasound, the device generates electromagnetic waves that penetrate the thickness of the walls, spreading through the wiring, driving the bugs out of 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.
• Bug Repeller Pest Redjekt combines ultrasonic and electromagnetic effects, so manufacturers have special expectations on the device. The coverage area is 200 m2, which allows you to limit yourself to one device for treating a room from bugs. The price of the device is 2000 p. You can order the device through the online store.

Electronic tools have different efficiencies, which depends 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 repellers have many fakes.Counterfeit is slightly 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 fake.

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

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

Reviews

Have bought ultrasonic repeller pest bug repeller, since we live in a private house and insects, mice and rats simply do not allow to live. We chose a repeller by watching ads on TV. I will not say that they were completely disappointed - the rats and mice disappeared, but nothing happened with the insects. Bedbugs on the couch both nested, and remained in it.

I got bugs after a trip to the holiday home. Tried to deduce folk remediesso as not to poison yourself with poisons. They began to bother a little less, but after a while they appeared again. I decided to purchase an ultrasonic repeller. Bought via the Internet AR-130 Smart-Sensor. He did not give anything, although I used it according to the instructions. But when I applied Reid facilitythen the bugs disappeared. And it took less than the drug was written. So, the device brought some benefit, although not the one I was hoping for.

Bought Tornado Beat FP-003. I heard a lot about him from friends. The device is nice-looking, it consumes a little electricity, it works silently. At first, the mice that gnawed under the floor disappeared. Then the cockroaches fled. I had to tinker with the bloodsuckers, but in the end get rid of bedbugs also succeeded. I don’t know for how long, but so far I haven’t turned off the unit. Let it work again.

I want to share my experience from using the ultrasonic repeller Ecosniper ls 919. I bought it from home bugs that just tortured the whole family. Insects to us crawled away from the neighbors. Called out professional disinfestation service. The respite was only 4 months, and then it all started again. I still did not like that the smell after pest control lasted a long time. Therefore, I decided to buy a repeller. not to breathe chemistry. The device has been working for a month, but there is no sense. I'll wait a bit more. If there is no effect, you have to look effective remedies for bedbugs and poison chemistry.
