Ultrasonic cockroach repeller: description and principle of operation

Kinds

Devices that repel cockroaches are distinguished by their versatility, parameters, properties, operating principle and range.

Ultrasonic

The device does not kill, but repels cockroaches using ultrasound. The waves travel quite far. Only when the frequency is high do cockroaches leave their habitat. Such devices do not have a negative effect on the human body or pets.

Magnetic resonance

The devices emit low-frequency electromagnetic waves. This forces insects to change their place of residence. The safety of a repeller directly depends on its power. Devices emitting low frequencies are unproductive: the devices only repel pests without killing them, but do not harm people and animals. Industrial magnetic resonance repellers are considered more effective, but they have a bad effect on the human body.

Electrofumigators and aquafumigators

Electrofumigators against cockroaches look the same as their anti-mosquito counterparts. To operate the device, special tablets are used, which emit a specific odor when heated. The aroma spreads throughout the room and repels pests.

Aquafumigators are considered a fairly strong and universal remedy. The device is connected to an outlet and a substance is released along with the water that repels and poisons cockroaches. Compared to other devices, the devices are low cost, easy to use, and quite effective. Cons: the substance may have an unpleasant odor and be harmful to health.

Ultrasonic cockroach repellers: features, operating principle

The device is a small device that is plugged into an outlet; battery-powered models are also available.

The operating principle of an ultrasonic repeller is quite simple: the device generates and delivers high-frequency sound waves, which have an effect on the nervous system of cockroaches. As a result, an unfavorable environment is created for insects: they cannot navigate in space, find food and water, and constantly feel discomfort. All this leads to cockroaches leaving the room and looking for a more suitable habitat.

The repeller operates in several modes, sending ultrasonic waves of different ranges. This is necessary to increase its effectiveness and prevent addiction in cockroaches. The area of ​​influence depends on the power of the device.

People and animals do not pick up waves of such frequencies, so the device is completely safe for them. Although rodents (guinea pigs, rats, hamsters) may be an exception, the device may cause discomfort for them.

For the device to be effective, it must not be placed behind a closet, under a bed, or in other similar places where waves will be reflected or absorbed. You need to choose a place as close as possible to the center of the zone where there should be no insects.

In addition, you should not expect all cockroaches to disappear immediately. The device should work for several weeks.

Tips for choosing the right model

The market is full of different types of repellers. Practice shows that not all proposed models cope with their task. Highly effective repellers are more expensive and get rid of pests. And dubious, low-cost ones cannot even repel mosquitoes, let alone cockroaches. In this regard, it is worth following certain tips when choosing the right model:

1. If the residents of a house or apartment purchase an expensive and undoubtedly powerful device, then it is unsafe to stay at home during its operation (about 4 weeks). The best solution would be to move out of the living area.
2. There are devices whose action extends to no more than a square meter. Such devices are best used in rooms where people do not live, or on the street. It is allowed to place several repellers in one room, which operate at a distance of up to fifty square meters.
3. It is necessary to carefully select the type of food. If you go on a trip or are outdoors, then it is better to use a battery-powered repeller. At home, it is recommended to use the mains power method.
4. To avoid accidentally stumbling upon a fake, it is best to buy the device in specialized and trusted stores.
5. When purchasing, you should pay attention to the range of the repeller. The device is not able to influence parasites through obstacles (furniture, walls, carpets).

Recommendations for using ultrasonic repellers

Are we scaring or luring?

If you decide to get rid of rodents using an ultrasonic repeller, then you will have to abandon other methods of “baiting”.

All other baits and traps must be removed. You cannot scare and attract at the same time. These are two opposing ways to get rid of mice and rats.

Using them together will not give any positive result at all. You will have the feeling that the ultrasonic repeller is not working.

Baits with poison do not enhance the effect of the repeller, but, on the contrary, reduce its effectiveness to zero. Rats (or mice) under the influence of ultrasound would have left your premises long ago, but the smell of food in baits or traps makes them come back.

Therefore, if we install a rat repeller, then we remove all the bait. Then it will be possible to really drive away all the rodents.

By the way, if you installed a mouse repeller the day before yesterday, this does not mean that you can now leave half-eaten sausage on the table.

Ultrasound does not pass through walls

First of all, let's take into account that ultrasound travels through the air, similar to light rays.

Imagine a table lamp. Will it illuminate the next room? 2nd floor? Basement and attic at the same time? Most likely no. Ultrasound works in much the same way. It does not pass through barriers.

It is reflected from hard objects and absorbed by soft ones. You can partially protect yourself from ultrasound even by covering yourself with a cape - just like from light.

Therefore, any ultrasonic repeller works effectively only within one room.

Ultrasound does not pass through walls and ceilings (floor, ceiling). And even the most powerful ultrasonic repeller is no exception.

Reflection and absorption of ultrasound

If there is no upholstered furniture, curtains, carpets or other soft objects in the room, then ultrasound, due to multiple reflections from the walls, ceiling and floor, fills the entire space as much as possible (Figure 1).

In this way, the best effect of the rodent repeller is achieved.

In rooms where there is upholstered furniture and other objects that absorb ultrasound, there will be a minimum of reflected ultrasound, or there will be none at all (Figure 2).

Here you can only count on the direct impact of the rodent repeller. In this case, it is better to use a more powerful ultrasonic repeller. The power reserve to a certain extent compensates for the lack of reflected ultrasound.

Nuances of effects on rodents

Ultrasonic repellers are designed to drive existing rodents out of the house, not to protect against one that is not there.

According to manufacturers who have actually tested their repellers, rats and mice simply get shocked by the ultrasound and appear numb at first.

From the point of view of their perception, it is unclear from where something unpleasant hits their “nerves”, causing severe discomfort. They are not able to immediately understand what is happening, so it often happens that in the first days of the repeller’s operation, people may see a rat running in circles or frozen in a daze.

After some time, the rodents begin to “understand” that something wrong is happening to them and try to get out of the ultrasound range. Therefore, the passports of repellers say that the time for rodents to leave is from 3-4 days to 3-4 weeks.

The manufacturer of the Tornado ultrasonic repeller said that one of his customers installed 4 powerful devices in the bathhouse, each of which could serve 400 m². And by morning, 16 mice were lying with their paws up - they had nowhere to go. The bathhouse was made to last, there was not a single hole in it.

There was another similar situation. One morning, after installing the appliances, the buyer opened the door to his shed and a whole family of rats with bloodshot eyes rushed past him through the door.

After such cases, a note appeared in the technical data sheets stating that it is advisable to leave a gap or hole into which animals can escape.

Battery repellers

Very often, with the onset of the winter season, people ask to be offered a battery-powered ultrasonic rodent repeller for installation in a room that is unheated in winter.

Dear comrades, batteries do not work in winter, they freeze.

On Chinese devices, which are mostly produced on batteries, the operating temperature of the device is not even noted. They only work at above-zero temperatures.

If you need to install an ultrasonic repeller in an unheated room where there is no electricity, then it is best to use a car repeller (for example, “Tornado-200 - 12K”), powered by a car battery.

Here the ultrasonic power is greater than that of a battery repeller, and the duration of continuous operation is many times longer.

Features of accommodation

Especially for small rooms (multi-room offices), we offer the Tornado-200 repeller for installation in each room. For apartments and country houses, we recommend installing at least one rodent repeller per floor, in the basement, or in the attic. In the basement - in each isolated compartment.

In apartments - in the kitchen or bathroom (where they penetrate through the riser). In warehouses, the number of devices is selected depending on the workload of the room.

Read more. It has been noticed that if there are canvas bags with food, feed, or something porous on the shelves, then the ultrasound simply “gets stuck” there. If you install one repeller in such a room, it will serve a very small area around it.

Therefore, in such a room it is better to install several ultrasonic rodent repellers. In other words, if there are racks, then the devices are installed in the spaces between the racks, regardless of the total area of ​​the room.

And finally, the only room whose footage can correspond to the footage specified in the technical specifications of the device is a room with shelving around the perimeter.

In this case, for a room of 200 square meters, you can install one repeller designed for 200 square meters. In all other cases, more devices are required.

How to properly install and use electronic repellers

The effectiveness of a repeller directly depends on the ability to place and use it correctly. To do this, there are some rules that must be followed:

1. It is advisable to use several repellers at the same time. This will certainly help get rid of a large number of parasites. One device is allowed in each room.
2. In order for the device to cover a larger area, it should be placed at a height of 1 m and only in a vertical position.
3. Due to obstacles in the room, the effectiveness of the ultrasonic repeller is reduced. The solution to this problem is to place multiple devices in the room.
4. After installing the device, be sure to monitor the condition of people nearby. If the action of the device negatively affects them, then it is better to refrain from using it and choose another method of combating parasites.
5. If the equipment has any damage or does not work correctly, it should be sent for repair. It is not permitted to use a damaged device.
6. Along with the repeller, it is also possible to use other methods to get rid of cockroaches.
7. Experts believe that ultrasound does not give instant results. Ideally, the repeller should work for about a month.
8. The device must not be disconnected from the network even for a short time, otherwise the cockroaches will return.
9. After installing the device, you need to monitor its temperature. Avoid overheating or excessive cooling.

Homemade devices are no worse

In some cases, a rodent and cockroach repeller can be created with your own hands from available radio components. The design is quite simple and undemanding in terms of exact adherence to denominations; prototyping is accessible even for beginners.

You can make a high-quality ultrasonic cockroach repeller with your own hands literally in one evening. There are many different schemes on the Internet, and spare parts for creating the device can be found in Chinese and Soviet radio equipment (old radios, players, tape recorders). The repeller circuit is very simple. Just one evening - and a pile of non-functional rubbish turns into an extremely useful device for any household or private apartment. It will become a real disaster for cockroaches, bedbugs and rodents. You can protect your home from these parasites by independently developing a device according to the diagrams provided on the Internet, or simply by purchasing a ready-made device.

It has been scientifically proven that ultrasound is quite effective against cockroaches. However, the tonality and frequency of radiation from homemade and industrial devices is not always critical for insects. This explains the low efficiency of devices sold on the market.

How effective are repellers?

There is still no consensus on what the results of using cockroach repellents are. Some people think that the product does not cope well with its intended purpose and negatively affects the health of its owners, while others admire its work and believe that it really helps.

The fight against parasites has been ongoing for a long time. Chemicals and toxic substances are used, but this is an extremely unsafe method. An electric repeller is easy to use, hassle-free and less dangerous. The devices produce sound at a high frequency from 18 kHz. Animals and people are not able to perceive such a frequency, but harmful insects are susceptible to its influence. Fumigators drive away cockroaches best if sound waves of different frequencies are used.

Reasons for the ineffectiveness of the device against cockroaches

Scientists conducted various experiments and found out how insects communicate - through ultrasonic signals. Most often, mosquitoes communicate in this way. Cockroaches are less sensitive to this type of repeller. The study showed that adult individuals do indeed leave their habitat when exposed to ultrasound, but this does not frighten juveniles so much. However, it cannot be said that the repeller is completely ineffective. The unproductivity of the device may be due to several reasons:

1. The equipment is incorrectly selected. Before purchasing, carefully study the area of ​​the apartment or house. Based on this information, a repeller suitable for the living space is selected.
2. The device is not installed correctly. Ultrasound does not pass through walls and other obstacles. Also, sound frequencies are reflected from a hard surface and absorbed by soft objects.
3. We saved on quality and purchased a cheap repeller from an unknown brand that does not inspire any trust.
4. Inattention. If the battery is low, the device stops sending ultrasound and becomes completely useless.

The cockroach repeller gives good results if you follow the manufacturer's instructions and advice. A high-quality repeller can be purchased from 900 to 7,000 rubles. Talk to specialists if you have any difficulties making your choice.

Advantages and disadvantages of electronic repellers

Positive sides:

• most often works quietly;

• unpleasant smell.

Universal rodent and insect repellers

Repellers of this kind will help get rid of different types of pests. They are used both in production and at home.

Russian repeller "GRAD A-1000 PRO"

A universal device that has 4 operating modes (against cockroaches, mosquitoes, low power and high). The range is up to 1000 square meters. The repeller can be used in different rooms (both residential and industrial). The desired result appears within 2 weeks. The device does not overheat.

Belgian ultrasonic repeller "Weitech WK600"

A powerful professional remedy against rodents and insects. Weitech WK-0600 is recommended for use in enterprises, warehouses, shops, etc. It can also be used for residential areas, but in the absence of animals and people. The power of the device was confirmed by laboratory tests. The model can operate in several modes. It is possible to adjust the range and signal level. When someone is present in the room, the device can be switched to “quiet mode”.

Ultrasonic “death” – myths and reality

Some irresponsible marketers have developed advertising concepts that a device emitting ultrasound can kill insects and even rodents at high intensity. Actually this is not true. Living beings simply do not like such sound effects, and it is incorrect to say that it is destructive for them. It is more likely that your cat or dog will suffer when the device is turned on than that insects will begin to die in shoals. In addition, if the technological process and settings do not match, the device may be useless for everyone - both animals and insects. The so-called destruction sound is nothing more than a fiction in the context of such devices. On the other hand, if we talk about low-frequency intense radiation of several Hertz, then it has a detrimental effect on both humans and animals (causes insanity, failure of internal organs). However, if you remember the ultrasound from cockroaches, then due to its physical characteristics it has a short range and intensity, while infrasound (low frequency sound) travels very far and is extremely dangerous for humans.

How to quickly get rid of cockroaches and why an ultrasonic repeller is the best solution

Pests cause a strong desire to get rid of them immediately. What methods are there?

• sprays, aerosols, dusts;
• powders, pencils, baits, gels;
• traps, repellers.

The most expensive way is to invite an exterminator, but you will have to pay a hefty sum for the services, which is not always rational. The best option is to buy an ultrasonic device for cockroaches. Why?

• a) Chemicals, solid, bulk, sprayed, can negatively affect the well-being of residents and pets.
• b) Most have a strong unpleasant odor and irritate the mucous membranes of the eyes, nose, throat, and respiratory tract.
• c) Dangerous when a person suffers from allergies; apply with caution if children and pregnant women live in the house.

New generation insecticides are less toxic, but they must be used with extreme caution.

Ultrasound is devoid of these disadvantages; devices based on it are positioned as the best remedy against cockroaches. High frequency sound has unique characteristics, which has given impetus to the production of various devices. It is not perceived by the human ear, but it scares away and throws insects, rodents, dogs, and any warm-blooded creatures into panic.

• Ultrasound depresses the nervous system, forcing you to leave your habitat against your will, and has the same effect on large and small cockroaches. Inside the organs and tissues of pests, the normal circulation of fluids is disrupted. The cells literally burst due to the fact that the water turns into a thick substance (colloid).
• Another spectrum of effects of ultrasonic waves is the ability to create increased intracellular pressure. Pests entering the affected area experience a sharp increase in temperature, which causes accelerated cell vibration. Metabolism and neural connections are disrupted, the creature experiences discomfort and leaves the dangerous place.

Why are supersonic waves harmless to humans and pets? It has been experimentally proven that there is a species-specific sensitivity to ultrasound of a certain frequency. Those that repel cockroaches, bedbugs, and other insects are not audible to humans. The hearing aid simply misses them.

Advantages of repellers

• operate silently, maintaining the room microclimate favorable for work, rest, and living;
• the room does not require preliminary preparation, as before treatment with chemicals;
• safe for humans and pets, will not cause allergies, diseases, nervous breakdowns, or discomfort;
• act quickly, the result is long-term, for reliability it is secured by periodically connecting the device for a short time (2-3 days);
• e) the device is reusable, works remotely, one (depending on the power) is enough to treat an area of ​​50-200 m2.

The ultrasonic cockroach repeller works 100%; you can read reviews and opinions about manufacturers and devices on our website.

Using a device to prevent cockroaches

The repeller is recommended to be used as a preventive measure, especially if there were already cockroaches in the house before. It is enough to use the device once every six months or a year. There is an ideal opportunity to turn on the device if residents leave for at least 10 days. It is advisable to use it in conjunction with other means. For example, cleaning regularly and keeping the house clean.

Modern efficient equipment, unlike chemicals, does not pose a danger to humans.
It is necessary to take into account the parameters, properties and characteristics of the devices in order to know for sure which one is best and most suitable for your home. Did you like the article? Was she helpful?
