Almost everyone has encountered the problem of cockroaches in their home. Not only is this an unpleasant encounter, but cockroaches are also carriers of various viral diseases. Therefore, experts do not recommend postponing the fight against them.
There are many folk and chemical remedies that are dangerous to human health, labor costs during processing, and constant repeated disinfection is required. But I would like to get rid of pests without harming my family.
Currently, a completely safe product for humans has been invented - an ultrasonic cockroach repeller. Many repellers only act on gnats and flies, but have no effect on cockroaches. Therefore, quite powerful repellers were invented, but they do not always help. This new product can be purchased in electronics stores, online stores and simple hardware stores.
How does an ultrasonic repeller work?
Many who purchase ultrasonic repellers hope to destroy the entire cockroach population forever. Sometimes this happens, but most often the number of pests decreases slightly. Ultrasonic waves do not kill “uninvited guests,” but only force you to leave your home and run to your neighbors.
High-frequency ultrasonic waves begin to influence the nervous system of insects, causing insects to feel uncomfortable, panic, transmit information about danger to their relatives, and are not always able to find food. After this, the “mustachioed” neighbors leave the apartment with unfavorable living conditions.
The ultrasonic device for cockroaches operates from a regular outlet. Some repellers have on and off buttons.
In order for unwanted insects to leave the house forever, you need to use the drug for 2-4 weeks, it also depends on the power of the device and the radius of wave propagation.
Does an ultrasonic repeller help with cockroaches?
There is a lot of controversy about the effectiveness of ultrasonic devices against cockroaches. Scientists have proven that this device is effective in getting rid of mosquitoes and flies.
Experts say that “mustachioed” pests are less sensitive to the effects of ultrasonic waves. It has been noticed that the drug has a greater effect on adult cockroaches, they begin to leave the apartment, but on young cockroaches, high frequencies have almost no effect at all.

Cockroach repeller Tornado-800
Although the device is intended for three rooms, ours only covers 2. However, after 1.5 months, not a single cockroach. In addition, there is no heating in one room, but the repeller independently maintains a comfortable temperature for it. I don’t regret the amount spent one bit.
Advantages of ultrasound products
- Safe for your health and the health of your loved ones.
- Does not affect pets.
- Easy to use. You need to plug the repeller into a power outlet and it will start working.
- Non-toxic. There are no unpleasant odors or chemical fumes.
- Silent for humans and animals.
- Long period of use.
Advantages of the model:
- Protects a large area
- the effective area of the device is
up to 50 sq.m. That's quite a lot for such a compact device! One repeller can protect a large room or office from cockroaches. For maximum effect, it is necessary to create conditions for the unimpeded passage of the repellent signal. - Generates an ultrasonic signal
- the device was created on the basis of many years of research, which showed that ultrasonic waves of a certain frequency create unbearable conditions for the life and reproduction of insects. An ultrasound generator is built into the body of the device, which distributes this signal throughout the room. As a result, cockroaches rush to move as far as possible from the sound source. - Does not cause addiction to cockroaches
- the range of emitted frequencies of the repeller is 13-27 kHz. During operation, ultrasound is constantly being rebuilt. Thus, a so-called “floating” ultrasonic signal is obtained, to which pests cannot adapt. The sound is different all the time, so the effect of the device is always preserved! - Safe, silent operation
- the human ear cannot hear sounds emitted at ultra-high frequencies. Ultrasound is precisely this type of sound. The repeller is completely silent for people! In addition, the device does not use any toxic substances - it can be used in bedrooms and children's rooms. - Automatic operation without settings
- the device is as easy as possible to use. All it needs is a 220 V electrical outlet. The repeller does not need to be configured; it works according to the algorithm laid down at the factory. The device is designed for 24/7 operation.
Typhoon LS 500-700
A domestic product that can repel insects, even mice. The impact radius varies from 80 to 200 m, depending on the purchased model. This device shows the best results compared to all other repellers on the sales market. The power of the Typhoon repeller is 4 W.
The cost of the repeller varies depending on the region, the price varies from 920 rubles to 1500 rubles.
Universal rodent and insect repellers
An innovative professional device produced by the Russian LLC "Ifo-Technology" "GRAD A-1000 PRO" can operate in four different modes, two of which repel rodents, another one repels mosquitoes, and one is intended for other insects. "Grad" services an area of up to 1000 square meters. m and removes all pests in two weeks of constant work. But its main purpose is to fight rodents. And he copes with this task perfectly. Also good reviews for repelling mosquitoes. But the reviews do not specifically talk about repelling cockroaches. Maybe because the weapon is too serious against them.
The Belgian ultrasonic repeller Weitech WK600 operates in nine modes and serves an area of more than 300 square meters. meters and in a wide spectrum of radiation 2-50 kHz. No one buys it to fight cockroaches separately. And the reviews contain little specifics, but users are happy with them. I would like to believe that, in addition to mice, mosquitoes and moths, cockroaches also disappear into the blue distances.
Ecosniper
A very compact magnetic resonance device developed in Hong Kong. The wave propagation area is up to 200 m. The manufacturer convinces that the low frequencies of the repeller have a detrimental effect on the nervous system of insects, which forces them to leave the room without hesitation. But reviews show that the product is not effective enough. You can purchase Ecosniper in an online store at an affordable price, around 1000 rubles.
Types of repellers
The main purpose of these devices is not to destroy, but to create conditions unbearable for the life of pests. Most often, repellers are used as part of a set of preventive measures, collectively called “barrier protection.”
The devices affect the sensory organs of cockroaches through signals of a certain intensity and frequency. Based on the type of radiation, repellers are classified as ultrasonic and electromagnetic. There are also combined gadgets that combine these technologies and have additional options.
Electrofumigators, which work effectively against small flying insects, however, have little effect on the behavior of cockroaches. In addition, most of these devices are designed to destroy pests, so these devices can only be classified as repellers conditionally.
Tornado OTAR-2
The manufacturer of the Tornado brand produces many drugs against cockroaches, but the Tornado OTAR-2 model turned out to be more effective.
Characteristics:
- Russian manufacturer.
- Double impact. In addition to sound waves, the device also emits light waves.
- The best place to place the Tornado repeller is to hang the product in the kitchen under the wall cabinets.
- For convenient placement there is a swivel mount.
- Price - 1000-1500 rubles.
Tornado brand repellers have both positive and negative reviews. Many people say that the number of cockroaches has decreased significantly, but over time they come back again.
Pest Reject
The product is made in America and has a wave radius of up to 200 sq.m. There is an additional cassette inside the device, which also affects the death of insects. But it is worth noting that this does not affect the health of family members and animals.
Many people recommend using Pest Reject in conjunction with non-toxic insecticides and traps. This is when the insects will 100% leave your home. The average price of the device is 400-600 rubles.
DIY bedbug repeller
For a person who is familiar with the basics of radio electronics and knows how to work with a soldering iron, making a bedbug repeller with your own hands is not particularly difficult.
Typical diagram and description of the device operation
The KR1006VI1 microcircuit is a timing element. It generates voltage pulses, the frequency and duration of which can be adjusted by changing the values of components C1 and R2. Changing the resistance of resistor R2 gives a frequency shift from 200 Hz to 55 thousand Hz. Against small insects, including bedbugs, it is necessary to adjust the generator to a frequency of 20 thousand Hz. From the third output of the KR1006VI1 timer, an alternating voltage of the required frequency is supplied to the sensor (speaker). Variable resistor R3 adjusts the signal power. In the absence of a KR1006VI1 controller, the device can be assembled using its closest foreign analogues, for example, the NE555 chip.
WK-600
This ultrasonic cockroach repellent is most often used in the food industry; it has a large coverage radius and is safe. The cost of the device is approximately 5,000 rubles.
To summarize: there are many opinions about the effectiveness of ultrasonic cockroach repellers. You can find many positive and negative reviews. But which side you noticed can only be found out by trying one of these devices in operation. It should only be said that not a single repeller kills the cockroach population, but only creates uncomfortable living conditions for insects, forcing them to leave your home. But there is no guarantee that they will not come back.
What manufacturers say
Commercials strongly recommend installing an ultrasonic cockroach repeller in your apartment. Since this is not the most budget-friendly purchase, you need to carefully study the information that manufacturers provide about their devices.
How it should work
Apartment owners, desperate to get rid of red pests using usual means, place great hopes on an electronic cockroach repeller. The manufacturers themselves describe the operating principle of the ultrasonic device as follows:
- by inserting the anti-cockroach device into a socket, the user activates high-frequency waves;
- insects, picking up signals, begin to panic and inform each other about the danger;
- with prolonged exposure to an electromagnetic field, coordination of movements occurs, insects lose interest in eating and mating;
- pests leave the premises - as the living conditions in it become unbearable.
Ultrasonic devices have low energy consumption. They can be connected to the network around the clock, without the risk of damaging the family budget.
How inefficiency is explained: 5 user mistakes
In response to increasing negative reviews of electromagnetic cockroach repellers, manufacturers have suggested that the users themselves are partly to blame for the ineffectiveness. Five errors are identified.
- Inattention. Perhaps the buyer was careless in reading the instructions and did not take into account all the recommendations for use.
- Wrong place. Ultrasound does not penetrate walls, carpets, thick curtains and furniture.
- The room is too big. Perhaps the range of the device is less than the area of the apartment.
- Extreme temperatures. A room climate that is too cold or too hot can negatively affect the performance of the repeller.
- Saving. Budget devices emit low-frequency waves, which pests quickly get used to.
Since cockroaches most often “walk” along the floor, it is recommended to install the device no higher than 1 m above the baseboard. It is important that the device is in an upright position.
