An ultrasonic bedbug repeller is a device that emits sound waves in the high frequency range. They are not perceived by the human ear. Many insects, animals and birds are able to hear these sounds. But why should they be afraid of ultrasound? Scientists have found that some insects communicate with each other using high-frequency sounds. The powerful ultrasonic signal emanating from the device should be associated with danger in insects and encourage them to immediately leave the room.
On a note!
The ultrasonic waves that the device is supposed to emit cannot be heard. If the device makes any sounds at different volume levels, it is faulty.
At the moment, researchers have not proven whether house bugs produce sounds at the same frequencies that most repellents emit. According to advertising, an ultrasonic device can repel bedbugs and force them to leave the apartment. Some manufacturers claim that their electronic products can kill insects by emitting low-frequency waves that have a detrimental effect on the nervous system of bedbugs.
Types of devices
Among the wide variety of ultrasonic repellers, there are three types:
- expensive professional devices equipped with broadband emitters capable of disseminating ultrasound 360° around at different frequencies;
- more affordable semi-professional devices with narrow-band emitters, resulting in less effective action on bed bugs;
- cheap home-made devices, inside of which sensors are installed that do not have any effect on the well-being of parasites.
The principle on which the operation of an ultrasonic device is based
To find out whether ultrasound helps against bedbugs, consider the principle of its operation. The idea of an ultrasonic repeller is based on serious scientific research. For example, it was found that many insects are able to hear sound waves of a certain frequency. However, some sounds can instill in them a feeling of anxiety and horror.
The first device to repel mosquitoes was built. And it really worked! The flying bloodsuckers hurried to leave the ultrasound coverage area. Then they started talking about the versatility of the device and began to use it not only against mosquitoes, but also against bedbugs, cockroaches, mice and rats.

Review
Last summer I worked as a teacher at a children's camp. And we got bedbugs. They couldn’t poison them with insecticides; the season would have to be disrupted. We purchased the ultrasonic cleaner WK-0600 based on reviews on the Internet. According to the instructions, we selected the ultrasound mode and turned it on for 4 days. The bugs have disappeared somewhere. No one else bit the children.

The effect of ultrasound on bedbugs
The main argument according to which ultrasound is not effective against bedbugs is that this type of insect does not have organs that produce sound, and therefore they do not have hearing organs. But scientists still have not come to a consensus on whether bedbugs make sounds. After all, not only the fluttering of wings or the friction of legs against legs can serve as a source of sound in insects.
Linen bugs
Bedbugs have sensitive hairs connected to nerve endings on their legs and abdomen. With the help of sensilla, insects sense thermal radiation and air vibrations. No hearing organs have been found in bedbugs, but high sensitivity to odors and temperature allows them to find food and a sexual partner.
Bacteria and viruses also do not have hearing organs, but ultrasound, thanks to the cavitation effect, successfully fights them. It is used to sterilize products, medical instruments, and drinking water. Under the influence of ultrasound, bubbles appear in biological fluids, which increase in size with prolonged exposure to sound. When bubbles burst, they have a shock and thermal effect, destroying the tissues of living organisms. The parasite does not have to listen to ultrasound to feel discomfort from repelling with ultrasonic waves.
The lower the ultrasound frequency, the easier it is to produce cavitation and the more aggressive its effect on living organisms. Therefore, many devices use a frequency of 20-22 kHz. It is impossible to say for sure whether ultrasound helps against bedbugs, since studies have not confirmed the effectiveness of repellers. But the synergistic effects of ultrasound and insecticides have been studied.
The ultrasonic agent creates cavitation in the parasite’s body, which increases its sensitivity to insecticides. Ultrasound against bedbugs together with insecticides are effective even against resistant insects. The combined effect, which has synergistic properties, also occurs when an electromagnetic bedbug repeller is used. It combines the action of ultrasound with magnetic radiation, enhancing each other's effectiveness.

Review
I don’t know where, but bedbugs appeared in the apartment. We started reading reviews about ultrasonic bedbug repellers. We opted for Ecosniper 919. We plugged it in, it worked for 2 weeks - no results, the body was still covered with bites. As a result, they called specialists from the sanitary service and carried out sanitation against bedbugs.

Advantages of repellers
Bedbug repellent devices are easy to use. There is no need to carry out complex manipulations that involve the use of pesticides. Repellers are absolutely harmless to humans , which means there is no possibility of getting poisoned or having an allergic reaction while working with insecticides.
The device allows you to easily reach hard-to-reach places , which often remain untouched when treated with various poisons. He will get pests in every nook and cranny where those pesky insects have found their way. Its effect extends to the entire area of the room, and insects have no chance to hide from the effects anywhere.
In addition, bedbugs gradually adapt to any chemicals, which cannot be said about a repeller. Insects cannot get used to its effects , so the effect of its use will last as long as it takes to completely cleanse the apartment of uninvited guests.
Tornado Impact FP-003
A universal device against bedbugs, the operating principle is based on two types of influence: ultrasonic and electromagnetic. The device emits ultrasound, which negatively affects the well-being of insects, and electromagnetic radiation, which travels through the wiring throughout the apartment and creates vibrations that are unpleasant for bedbugs. Such comprehensive repelling of pests forces them to leave the premises in a short time.
The operation of the repeller does not affect the functioning of other electrical devices operating from the same network. The energy consumption of the device is insignificant, which will not affect monthly utility costs. Ultrasound does not have any effect on apartment residents.
- overall dimensions: 155x90x65 mm;
- device weight: 170 grams;
- supply voltage: 220V;
- Signal coverage area: 650 sq. m;
- price: 1000 rubles.
Review
My grandfather had bedbugs in his village house. He is an elderly man and will not poison parasites with insecticides. We decided to buy him a Tornado repeller. Based on reviews on the Internet about it, we came to the conclusion that it was worth taking. It can work in different modes. We installed a repeller, turned on the ultrasound, and after two weeks the bedbugs disappeared. I recommend Tornado to anyone looking for a reliable home protector against pests.

Development prospects
Currently, radio frequency devices are being tested that do not repel bedbugs, but, on the contrary, attract them. The action is similar to ultrasonic traps for cockroaches and ants. Only in the case of bedbugs it is much more difficult to do this. The principle of operation is based on the fact that when an insect enters a certain area, it is subjected to a fatal attack of sound waves. The body continues to remain in its place. As a result of further exposure, it begins to emit pheromones, which attract “relatives” better than any bait.
It is difficult to imagine the cost of the device when it appears on the market. But the possibility cannot be ruled out that in 10 years it will replace insecticidal preparations and other means of combating bedbugs.
How effective the miracle device is can be judged from the reviews of ordinary users. Because even the opinions of scientists on this matter are divided. Some argue that bedbugs are completely insensitive to this kind of sound, while others cite examples of effective research in favor of repellers.
However, the fact remains that ultrasonic waves are not a lethal weapon for bedbugs. If we assume that everyone starts using them, insects will simply wander from place to place. One day they will come see you again.

Fumigators and sections against parasites as a remedy against bedbugs
It is impossible to destroy all bed bugs in an apartment with fumigators: even if the insects die from these agents, they will die slowly and not all of them. But fumigators are quite suitable for repelling parasites for a short period of time.
So, for example, they can be used:
- if necessary, spend the night for a short time in premises of questionable cleanliness;
- and also in your home for cases when it is not possible to immediately destroy bedbugs - there is no time or the necessary insecticidal agents.
It is also useful to read: Tsifox bedbug repellent
And one more thing: Since bedbugs drink blood, can they transmit AIDS or hepatitis from one person to another? Let's find out...
Fumigators should be plugged into an outlet located as close to the bed as possible. The deterrent sections should be hung directly on the bottom rails of the bed frame. For such short-term repelling of bedbugs, you can use Mosquitall, Raptor and Raid fumigators, as well as Mosquitall and Raptor moth sections.
Review
“After buying a new apartment, it turned out that there were already tenants living in it - moths and bedbugs. It's good that we discovered them before entering. For butterflies we bought special Mosquitall sections with the scent of lavender, they helped. It even seemed to us that there were fewer bedbugs after placing these sections. But we were able to get them out only when we called the SES. The guys handled everything very quickly; there was no good furniture in the apartment.”

On a note
Before using repellents, you should check that there are no bedbugs in the bed itself, the mattress or the bedding - in this case, regardless of the use of fumigators and repellent sections, the bedbugs will still reach the body.
