It would be hard to find more problematic household pests than rats and mice. They carry deadly infections, damage electrical wiring, which leads to fires, and destroy food. All attempts by people to cope with them with the help of mousetraps and poisons have short-term success and have not solved the problem globally and are not solving it. On the contrary, they have driven her into a cycle with no end in sight.
Poisons and traps are dangerous for children and pets. A dead rat outside the home can poison predators and pets. Inside the house, it becomes a source of foul odor from a decomposing corpse (although this has been avoided with modern mummifying baits).
At this time, rodents, in order to replace dead individuals, multiply intensively, increase the number of young animals, and instead of long-term disposal of them, people get thriving populations of household pests.
Rodents are a unique order of mammals, with their own anatomical and physiological characteristics. It seems that nature itself has made them pests. They have an almost entirely cartilaginous skeleton, allowing them to easily penetrate into any cracks and holes. They have quite complex behavior. They prefer to move carefully along walls rather than in open space. Active at night.
Operating principle
The main advantage of the devices is that there is no need to kill animals and get rid of their corpses. Repellers provide room protection in a different way. They emit high-frequency impulses that act on the nervous system of rodents. Thanks to this, they try to leave the territory as quickly as possible. During operation of the device, the wave frequency changes in the range of 20-70 kHz so that rodents do not get used to it.
Some models combine the combined effects of high-frequency ultrasound and low-frequency electromagnetic waves. They are more effective; animals do not have time to adapt to them.
Types of devices
When choosing this device, you need to take into account the characteristics of the room where it will be used, the principle of operation, and power. The presence of a power source is also important. If there is no electrical wiring in the room, then it is better to take devices that run on a battery or battery.
Based on their operating principle, rodent repellers are:
ultrasonic; electromagnetic; combined.
To make your choice easier, you need to know all the advantages and disadvantages of different types of devices.
The rating of the best robotic vacuum cleaners and characteristics of the models can be seen in this article.
Electromagnetic
They emit electromagnetic pulses along electrical wires, which have a negative effect on pests. During the initial operation of the device, the number of rodents may increase significantly. This is caused by the fact that they begin to crawl out of secluded places in search of a way out from the action of electromagnetic waves.
Advantages of this type of repeller:
environmental safety; possibility of continuous operation; absence of harmful chemical compounds; no impact on the operation of other electrical appliances in the house; the ability to lure parasites out of voids and ceilings.
The main disadvantage of electromagnetic repellers is that to achieve the desired result, the electrical wiring must be installed around the perimeter of the entire room. This is not always possible. In other cases, using the device will be pointless.
Ultrasonic
They emit ultrasonic waves that have a detrimental effect on the nervous system of mice and rats. They lose their orientation, they are overcome by a sense of danger, and the rodents begin to look for an opportunity to escape from the field of influence of the repeller.
For humans, ultrasound is invisible and safe. Therefore, ultrasonic repellers can be used in any premises. They are also safe for rodents, but create conditions under which they cannot be in the area of their influence.
Advantages of ultrasonic rodent repellers:
environmental friendliness; possibility of continuous operation; repels both rodents and insects; safety; do not contain chemicals.
Minuses:
valid only within the boundaries of one premises; The ultrasound does not pass through walls; To completely get rid of pests, you need to use several devices simultaneously. The effectiveness of ultrasound is reduced if there are a large number of textiles, soft and paper objects in the room.
To prevent rodents from adapting to constant ultrasound, it is better to purchase devices in which the frequency of ultrasound vibrations can be adjusted in different ways.
What devices does the market offer?
There are many models for protecting a home, apartment, industrial premises, etc. Some devices are equipped with additional functions. They differ in the type of power supply and connectors.
Some devices additionally generate electromagnetic pulses along the wiring. Combined devices better cover the entire building, since the radiation passes through partitions and walls.
average cost
The average cost of repellers in online stores and retail outlets differs depending on the model and manufacturer. The price of devices for apartments and private houses rarely exceeds 3,000 rubles.
Selection criteria and features
To find a high-quality repeller, you need to focus on a number of indicators and characteristics. With these devices, you need to pay attention to the cost. The larger it is, the higher the likelihood that the repeller will work effectively. This does not mean that budget devices are absolutely useless. In rare cases there are exceptions. But, as a rule, devices costing less than 1000 rubles are ineffective against rodents.
Based on the technical characteristics, you can determine the capabilities of the repeller. There are cases that the actual characteristics do not correspond to what is indicated in the description.
What you need to pay attention to when choosing a device:
Operating principle: it is better to use ultrasonic or combined devices against rodents. The area of influence of the device must be larger than the intended protected area. In this case, it is necessary to take into account the intensity of the pulses of the emitted waves, the presence of obstacles in the room (curtains, upholstered furniture). For domestic conditions, the optimal exposure area is 400-800 m2. Sound pressure - it should be in the range of 80-120 dB. The lower limit of the audio frequency range should not be less than 20 kHz. A person should not hear how the device operates. Periodically, the frequency of the waves needs to be varied so that the rodents do not have time to adapt. Wave radiation pattern - the larger it is, the better. High-quality repellers have a range of close to 360°. But even directionality within 200-270 ° is a good indicator.

Which model is better to choose in your case?
Tornado 200
There is such a variety of ultrasound devices on the market that a person unfamiliar with the topic may get confused. Let's start with the basic model Tornado 200, intended for use at home. It can protect a room of up to 200 m2 from rodents (according to the manufacturer), in fact, the effective area of the device is much lower.
We are talking about residential and office premises where there is no food. The fact is that rats and mice, overcoming panic and fear of ultrasound, nevertheless do not leave the premises where food supplies are available.
The cost of the model is 1500 rubles. Most suitable for empty rooms and areas. In crowded rooms (furniture, appliances, etc.) more powerful ultrasound emitters should be used.
This is the “weakest” (in terms of its characteristics) device and reviews about it are quite contradictory - users often say that the device’s power is clearly not enough and advise them to switch to older models in the line.
Tornado 300
For a larger area, more powerful devices are needed, such as the Tornado 300. It has 2 emitters . Under its reliable protection there can be a 3-room apartment with a kitchen and dining room.
Recognized as the most optimal device against rodents in terms of price and quality ratio. Today Tornado 300 is the most powerful in its class ( household appliance for use in an apartment/house/shed/garage) ultrasonic repeller of rats and mice , including bats.
The sound pressure created by the Tornado-300 does not exceed the permissible limits of SNiP.
The cost of the device is 1900 rubles.
Tornado 400 and 800
The time has come for the “heavy artillery.” The next two devices are real “professional tools” among ultrasonic rodent repellers.
To protect commercial organizations and warehouses from rats and mice, you can use the Tornado 400 and 800 models. The first can clear rodents from, for example, a dining room, grain storage, warehouse or attic of a country house. The device is also suitable for residential areas if maximum coverage of the territory is required. When installing repellers near doors, it is possible to protect areas along the walls along which pests most often move.
- The cost of the Tornado ultrasonic repeller is 400 - 2100 rubles (effective area - up to 400 m2)
- Tornado 800 - 3150 rubles (effective area - up to 800 m2)

The Tornado 800 model, due to its design, is effective in:
- elevator shafts;
- hangars
- corridors, underground communications and tunnel corridors,
- at dachas in cellars;
- in poultry farms and cattle breeding complexes;
- in sanatoriums and children's camps;
- storages of vegetables and grains.
Reasons for the lack of effect from the repeller
If a repellent device was installed, but rodents still remain, this may be caused by several factors:
Low-quality, cheap device, the technical characteristics and parameters of which do not correspond to the assigned tasks. Wrong location. You need to buy a repeller that will take into account the characteristics of the room. Exposure to low temperatures. Battery-powered devices are especially susceptible to temperature changes. They can break quickly. Incorrect operation. The new device should work continuously for 3 weeks. Then you need to pause.
Note! If the manufacturer claims that the repeller is universal against rodents, insects, moles and other pests, then this is impossible. Most likely, the device will be useless or not as effective as stated in the description.
Popular models
The choice of repellers for the home is huge. Some models are especially popular due to their efficiency and technical characteristics.
