Trying to get rid of bedbugs, many people turn to high technology, namely, ultrasonic repellers. This is done for a number of reasons:
- Ultrasonic bedbug repellers are cheaper than a good insecticide.
- Ultrasound is harmless to humans, unlike most insecticides, which can cause poisoning if handled incorrectly.
- Ultrasound does not cause allergies.
Manufacturers of ultrasonic repellents claim that their products can repel and kill bedbugs, and some even claim that ultrasound prevents the insects from reproducing. However, does this product really help in the fight against bedbugs? This is exactly what this article will be about.
Market offers
Now on the market you can find several types of ultrasonic devices against crawling insects. Manufacturers promise quick and long-term expulsion of bedbugs and cockroaches from your home or apartment. Take, for example, the Bulgarian engineering miracle EMR-21, which can repel rodents, ants, mosquitoes, flies, cockroaches, centipedes, bedbugs and even annoying neighbors.
Russian manufacturers produce several devices at once, the most famous of them are the Eco-Sniper 9BLS-989 and Typhoon LS-500. In the second, the developers installed a microcircuit that is responsible for constantly changing the frequency of the ultrasonic wave. This is done so that insects cannot get used to the irritating signal coming from the device.
There is also a specialized ultrasonic bedbug repeller UP-116T on the market, made to combat crawling insects exclusively. Since the device is special, its price is at a special high level.
Not without Chinese manufacturers, who offered a whole range of repellent devices operating on ultrasound and magnetic fields. For example, in the AR-130 Smart-Sensor, parasites are dealt a double blow at once and such a miracle of technology costs only about $10.
What is the composition of insecticide?
Insecticide is a fairly modern remedy. It was developed by an institute that deals with problems of this nature. This is practically the only product that is designed specifically to kill bedbugs. It does not work for other insects.

As a rule, when choosing a bedbug killer, people want it to be effective and safe. In terms of effectiveness, this product is one of the best. But his security is not very high
Therefore, if you decide to use this remedy, pay special attention to protecting your body and your loved ones
The product contains substances such as piperonyl butoxide, permethrin and cyperiethrin. The drug has a shelf life of about two years. Do not store it near food under any circumstances. You can get severe poisoning. Insecticide is developed on a natural basis; it is recommended to dilute it with warm water. And also if you are allergic, it is better not to use this remedy, as a serious allergic reaction may develop.
Laboratory tests
Scientists could not help but react to such an active growth in the production of new ultrasonic devices for insect control. Tests were carried out on rodents and various types of insects, both in Russia and in the USA. Typically, the work was carried out on behalf of private companies who wanted to determine the most effective type of device before its mass purchase to protect warehouses, work areas and other premises. Among other things, scientists tried to find the optimal bedbug repeller available on the market.
After analyzing the data from these studies, the following conclusions can be drawn. Only every fifth device is suitable for rodent control (tested on rats). At the same time, these devices belong to the professional category, are expensive and are produced in limited quantities, but they allow you to achieve long-term results. But the emitters, which are widely represented on the market, have a beautiful design, colorful packaging and are promoted in the media, almost all turned out to be dummies. At best, they give only a short-term effect: rodents become inactive for a short period, but very quickly adapt to the new stimulus and completely stop paying attention to it.
During tests on insects, the optimal result was obtained on mosquitoes. These flying insects communicate using ultrasonic waves, including signaling danger to their relatives. Devices in which the mosquito alarm signal has been copied fairly accurately will reliably protect your home from flying bloodsuckers.
The effect on ants and cockroaches was short-lived and only caused disorientation and decreased activity. The insects temporarily curtailed their vigorous activity of colonizing the room, but had no intention of leaving. But ultrasound did not make any impression on bedbugs at all.
How do bedbugs react to ultrasound?
To understand why bedbugs remained indifferent to ultrasonic repellers, it is worth taking a closer look at the structure of insects. Only bed bugs drink blood, which, unlike most of their relatives, do not have wings - and their insects are used not only for flight, but also for creating the necessary sounds.
Blood-sucking bugs do not have other organs with which they could create sounds. And if there is nothing to talk about, then what is the point of hearing something?
Now many scientists adhere to the theory that the hearing organs of bedbugs are not just in an embryonic state, but do not function at all.
That is, in fact, when installing an ultrasonic sensor to expel bedbugs, you are trying to annoy your deaf neighbor with loud music. If you make the music very loud, then your neighbor’s walls and windows will shake and he may notice your efforts, but you won’t be able to force him to look for another house in this way.
But folk remedies such as lavender and wormwood, on the contrary, can work much better than electronics. Bed bugs receive basic information about the environment through their sense of smell, and therefore prefer not to live in rooms with strong odors.
Why ultrasonic repellers are a myth
Like many insects, bedbugs use smells rather than sounds to communicate and feed. These insects have a sense of smell that any dog will envy - it is by smell that they find their victims, places to build nests and ways to enter the apartment.
But their other senses are greatly dulled, so they are unable to listen to ultrasound. This is why ultrasonic repellents against bedbugs are absolutely useless.
The commercial success of these devices is explained by the trust of consumers in technology, fear of “chemistry” and, of course, the unscrupulousness of sellers who are ready to attribute any properties to their products.
Remember: ultrasonic waves cannot repel, kill, disrupt the reproduction cycle, or otherwise affect bed bugs in any way. This is pure myth, as evidenced by numerous reviews from deceived customers.
Pest Reject from bedbugs
Today a new ultrasonic drug against bedbugs has appeared on the market - Pest Reject. The bedbug repellent device is inexpensive, but if you evaluate it from the point of view of customer reviews, they are mostly positive.
An ultrasonic device for bedbugs produces ultrasound as well as electromagnetic pulses. All this together affects the nervous system of the bug. After activating the device, the bug begins to feel restless, cannot orient itself in space and is forced to run away from the room in panic.
Unlike other forms of pest control, this device has a number of advantages:
absence of extraneous strong odors; safety for human health and pets; no attachments or additional components are needed; does not cause addiction to parasites; effective over a large area.
A device for killing bedbugs can be used as a means of controlling or preventing parasites. Its average price is about 1,500 rubles, and the operation of the device does not put a large load on the network.
Despite the fact that scientists have discovered that parasites do not perceive ultrasound, the drug also affects them using an electromagnetic pulse, which has the desired effect.
According to reviews of the device, it has a positive effect. After 2-3 days of exposure, all adult individuals leave the apartment, and after 2-3 weeks, the remains of the parasites, which will hatch from the eggs at this point, leave. In this case, there is no need to carry out repeated treatments, leave the apartment for the duration of the device’s operation, or carry out general cleaning. Ease of use, minimum effort and high efficiency – these are the main advantages of the drug, which can be bought at any household store.
How to use it correctly
The product is sold in the form of a concentrated liquid, which must be used to prepare a solution. The drug is accompanied by instructions for use, which provide information regarding the proportion for preparing the solution for each type of insect. Changing the proportions yourself is prohibited. To kill cockroaches, use the following proportions: 5 ml should be used per liter of water. facilities.
Remember that you will be working with a toxic chemical, so the use of protective equipment is required. All safety measures must be observed so as not to harm the health of people and animals living in the apartment.
At the first stage, it is necessary to prepare the premises. You always need to take into account the degree of contamination of the room. If the infection is severe, a full treatment of the entire room will be required; if the infection is minor, you can apply the product in the kitchen, toilet and bathroom.
Required:
- Move the furniture away from the walls so that you can treat the baseboards and back walls of the furniture.
- Hide all food products in sealed bags and containers.
- Remove all dishes, kitchen utensils, towels and personal hygiene products.
- Next, sweep, remove cobwebs and dust, and wet clean.
Treatment
The preparation of the solution, as well as the treatment itself, is carried out using protective equipment. It is necessary to wear protective overalls, you can use pants and a long-sleeved jacket. Choose shoes that can be easily washed off with water after the procedure. Rubber gloves, safety glasses and a respirator are also used. The substance must not be allowed to come into contact with the skin, mucous membranes or respiratory tract. When the solution is prepared, it is poured into a spray bottle.
It is necessary to apply the substance to those surfaces where the Prussians have been seen, as well as to those places where they are most likely to appear. Treat baseboards around the entire perimeter, the back and bottom of cabinets, behind the refrigerator, radiator; be sure to treat pipes, the bottom of the sink, and washbasin. In the bathroom and toilet we apply the substance to corners, pipes, and ventilation holes.
After the procedure, you need to remove protective equipment, change clothes, wash your hands with soap, and wash your face. The room must be left for at least 2 hours, with the windows closed.
Upon returning to the apartment, it is necessary to ventilate it well, it is better to create a draft. Next, prepare a soap solution and treat absolutely all surfaces with which a person comes into contact.
It is especially important to pay attention to cleaning when children and animals live in the apartment. Contact with the drug may cause serious consequences. The pesticide remains only in hard-to-reach places
The pesticide remains only in hard-to-reach places.
Preventive actions
After the procedure, it is imperative to pay maximum attention to preventive actions, as this will protect against the appearance of new pests. Do wet cleaning more often, wash dishes after each preparation and meal.
Keep the table and work surfaces clean and remove crumbs. Do not leave food on surfaces. Take out the trash daily and wash the trash can. After washing dishes, wipe the sink dry. Eliminate water leaks and seal all cracks. Use preventive measures, you can turn to traditional methods.
Conclusion
Summarize. Ultrasonic repellers have a right to exist, but they will not have the desired effect in the fight against bed bugs. Their maximum is a short-term decrease in parasite activity, but even this effect is observed very rarely.
Such sensors can be used as a preventive measure after chemical treatment of a room, in order to prevent a re-invasion. Perhaps the radiation will prompt the insects to think about finding more hospitable hosts, although, as laboratory studies show, bedbugs ignore ultrasonic arguments very well.
As for the manufacturers of such devices that promise protection against bedbugs, the most honest of them are the Chinese, who at least set minimum prices.
