Finding a house without cockroaches is almost impossible. Black, red or red insects settle with equal pleasure in clean, lived-in apartments and in garbage dumps, abandoned houses and sewer mines. Not only is the neighborhood unpleasant from an aesthetic point of view, pests are carriers of pathogenic microorganisms and can cause allergies and transmit cholera and other diseases.
It is also worth knowing that cockroaches do not disdain to feast on all possible products and enjoy damaging wiring, mechanisms and electrical appliances. The female’s fertility is enviable; in one season she is capable of completely renewing the ranks of the “cockroach army,” which causes significant damage to a person’s peace of mind. Pest control has been going on for several millennia, but today a way to eliminate it has been found - these are cockroach repellers. Safe for human health and pets, the anti-cockroach device will successfully deal with insects of any type and in any quantity.
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.
Fumigators - cockroach repellers
The operating principle of electrofumigators is based on heating special chemicals and their subsequent evaporation into the air. Evaporation negatively affects the sense of smell of insects. There are a lot of options for carriers of irritating chemicals, since the operation of the devices is based on a single principle.
Inside the device there is a ceramic element with a spiral. During operation, the latter is heated to a temperature sufficient to slowly evaporate the contents of the carrier.
Fumigators that work well against mosquitoes work poorly against cockroaches
Manufacturers of such devices claim that their devices are safe for humans, but the odors emitted when the poisonous plate is heated or the liquid evaporates are quite pungent. Vapors can cause people to feel worse, so being in the same room with a working electric fumigator is extremely undesirable. After turning off the device and ventilating the room, the effect on pests stops.
Despite all the disadvantages, electrofumigators are not without steady demand in the market. This is due to their relative effectiveness and reasonable price.
By the way, much more effective aquafumigators for the most part are not repellents, but work to exterminate pests.
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:
- 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.
- 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.
- 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.
- To avoid accidentally stumbling upon a fake, it is best to buy the device in specialized and trusted stores.
- 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).
Effect on the body of insects
Electronic cockroach repellers An electronic cockroach repeller produces ultrasound of a certain frequency.
The human ear cannot detect it. According to manufacturers, the work of the exterminator does not affect the well-being or health of a person, therefore the products are classified as safe. Ultrasound prevents insects from finding food, a pair for mating, and does not allow them to orient themselves in space. Ultrasound can repel some insects, but not cockroaches. The mechanism of action on Prussians is somewhat different.
Interesting!
There is also an ultrasonic trap that does not repel insects, but attracts them to itself. The pests approach the sound source; there is a grid on it with an electric current supplied. The insect receives a shock and dies instantly. In this way it is capable of destroying all flying insects. An example of such devices is the Terminator lamp range.
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:
- 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.
- 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.
- 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.
- 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.
- 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.
- Along with the repeller, it is also possible to use other methods to get rid of cockroaches.
- Experts believe that ultrasound does not give instant results. Ideally, the repeller should work for about a month.
- The device must not be disconnected from the network even for a short time, otherwise the cockroaches will return.
- After installing the device, you need to monitor its temperature. Avoid overheating or excessive cooling.
Measures to prevent the appearance of cockroaches
It is not enough to install cockroach repellers; you need to create the most uncomfortable conditions for the subsequent appearance and reproduction of pests. As soon as domestic cockroaches appear, you should get rid of the uninvited guests. Prevention is as follows:
- Conduct a general cleaning of the premises (if possible). Remove food from public access, shake all bags of cereals and pasta. The easiest way is to place supplies in airtight glass or plastic containers. Pay special attention to bread, pastry and sugar - these are the favorite delicacies of pests.
- Check the pipeline for leaks. The main areas where insects are located are damp and dark places. Cockroaches need a source of water for rapid growth and raising offspring.
- Do not leave dirty dishes with food out overnight, put food away, clean out cabinets, and keep the kitchen, bathroom, and powder room clean. Crumbs on the floor will quickly attract hordes of pests, but getting rid of them will be more difficult.
- In damp rooms, ensure good ventilation. Condensation on the walls, remnants in the soap dish, rot in the area of pipe joints, mold - all this is the favorite food of insects.
If a garbage or ventilation shaft in a multi-story building is clogged and has not been cleaned for a long time, it is a breeding ground for insects. A cockroach repellent device will help here for a short time. To clean the channels, be sure to call a technician from the management company. In order for the cleaning to be done quickly, you need to write an application addressed to the director of the management company - according to the law, the director is obliged to respond to the signal and put the common property in order as quickly as possible.
It is interesting that in private houses made of wood, cockroaches practically do not appear. But here you can find various woodlice, spiders and other equally unpleasant guests in abundance. The electronic repeller also works against these “neighbors”, and at the same time will prevent the appearance of “red mustaches”.
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.
Reviews
Reviews about the use of ultrasonic and electromagnetic repellers have different responses, since much depends on the degree of contamination of the room, correct use and selection of the appropriate device.
I once tried an ultrasonic repeller. Yes, it works, but not for long. When its effectiveness ends, the Prussians appear again. So I decided to carry out chemical treatment together with my neighbors and let’s see what comes of it.
Marina, Saratov
It so happened that the cockroaches themselves disappeared, since we live on an avenue where there are a lot of different communications. They most likely couldn't handle all the noise and we haven't had them for several years.

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:
- 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.
- 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.
- We saved on quality and purchased a cheap repeller from an unknown brand that does not inspire any trust.
- 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.
Operating principle of the device
Many owners hope that after installing an insect repeller, the “longhorned beetles” will disappear forever. In some cases this happens, but more often the insect population decreases slightly. Ultrasound does not destroy pests; sound waves only repel cockroaches.
In the instructions, manufacturers indicate the following principle of operation of the device:
- when plugged into the network or installed lithium ion batteries, the device emits high-frequency waves;
- insects feel a negative influence, panic, transmit danger signals to their relatives;
- with prolonged exposure to ultrasound and electromagnetic pulses, cockroaches move randomly, lose interest in mating relationships, and do not always find food;
- pests gradually leave the home with unfavorable conditions.
Important! To achieve a positive result, you need a sufficiently powerful device so that the impact on the processes of nervous regulation is maximum. When using a low-power device, cockroaches are unlikely to leave the room.
Advantages and disadvantages of electronic repellers
Positive sides:
- most often works quietly;
- safe for animals and people;
- a large assortment;
- the device operates at a distance;
- used several times.
Negative sides:
- May be harmful to rodents and small animals;
- high price;
- unpleasant smell.
