The problem with rodents worries many owners of apartments and private houses. These animals not only spoil things, but also spread diseases that are dangerous to human life. Fortunately, today a large number of rodent repellers have appeared, the operating principle of which is based on the emission of electromagnetic or ultrasonic waves. The device emits a wave of a certain frequency and amplitude, which has a negative effect on the senses of large and small pests, forcing them to leave the occupied areas.

When choosing a repeller, you should pay attention to the following characteristics:
- Power. A parameter that directly affects the operating range of the device. If we are talking about ultrasonic repellers, then it should be remembered that the acoustic wave is not able to pass through walls and spreads within a limited space. In turn, radiation from electromagnetic devices can spread through walls, simultaneously expelling rodents from the voids of partitions.
- Distribution range. Ultrasonic repellers, compared to electromagnetic repellers, have a larger area of propagation of the acoustic wave, which reaches about 400-1000 square meters. m. In turn, magnetic models are limited to 200 sq. m, however, they give a more uniform field that does not deviate from the spread when encountering obstacles. Before making a choice, pay special attention to the environment in the “cleaned” room.
- Sound pressure. The higher this parameter, the more effectively the repeller works. The optimal pressure indicator varies in the range of 110-120 dB - when choosing a device, proceed from these values.
- Power supply type. Repellent devices powered by electricity usually have high power and a larger wave coverage area. In turn, autonomous devices are more convenient to place in non-electrified rooms, but their efficiency will be lower than that of stationary models.
- Operating frequency, which must be strictly above 20 kHz. To determine how accurately the repeller reproduces this parameter, you need to turn the frequency control to minimum and listen - if the device makes a squeak, it means that the technological requirements are not met.
The best repeller manufacturers
Before a detailed review of the list of the best, it is worth mentioning the leading companies in this market segment.
- "Tornado". One of the oldest manufacturers on the Russian market, developing traps for 25 years. It enjoys a reputation as a distributor of inexpensive and very effective repellers of various power levels.
- "EcoSniper". A young Russian company that started operating in 2013. It is interesting because in such a modest time frame (only five full years) it managed to break into the top in sales of traps in the country.
- i4Technology. The company that owns the most famous brand of repellers “Grad” in Russia. Engaged in the development of a wide range of special traps that are very popular among consumers.
- Weitech. The Belgian company is one of the few representatives from abroad that has managed to gain a foothold in the domestic Russian market. It has gained popularity due to its commitment to humanism: Weitech traps do not require the involvement of poisons in the process of repelling rodents - their effectiveness is achieved solely through the creation of an ultrasonic barrier.
- SITITEK. A Chinese corporation engaged in the production of household appliances and electronics for two decades. In 2013, the official sales representative office of the company was opened in Russia. It is a strong middle peasant in the domestic market in terms of sales of rodent repellers.
- Chiston and Co. Another representative of Russia, who launched production back in 1991. Having started out as suppliers to the military-industrial complex, mechanics and electronics, the company gradually moved into the development of household goods. It is one of the segment leaders in the production and sales of rodent repellers.
Ultrasound radiation power is the most important indicator in the device
Another misconception used by careless manufacturers. They claim that “our device is more powerful, which means it performs better.” But the power indicator is important only in one case - when calculating the area of influence.
For example, devices with coverage up to 800 sq. m. will differ from models of the same type, but designed for 400 sq. m. For example, Tornado repellers with a power of up to 1200 sq. m. are equipped with two or more emitters. This explains their increased power.
Conclusion: Before checking whether repellers work in a room or house, pay attention to the power of the device and the area of the room. For compact rooms, too “strong” devices are not needed - increasing the power rating will not make the devices work better!
The best electromagnetic rodent repellers
Unlike ultrasonic repellers, the action of electromagnetic devices is based on the creation of a single magnetic field of a special kind. It is generated thanks to the home electrical network and spreads throughout the protected area in pulses at certain time intervals. The main advantage of such devices is the virtual absence of interference, since the electromagnetic field, unlike ultrasonic waves, can “pass” through the wall. The disadvantage is expressed in the small area of action - the radiation of the most powerful devices can cover only up to 200 square meters.
Ultrasound power affects its effectiveness
Absolute nonsense! Sounds and ultrasounds are different physical phenomena with their own wave vibration parameters. People do not hear ultrasonic repellers, but insects and animals catch them.
Mice, rats, and other rodents clearly distinguish noise waves with a frequency of 1 GHz. For them, this is a real acoustic attack, in which their nerves are tense to the limit and there is only one instinctive feeling - to run.
A person cannot hear wave vibrations up to 20,000 Hz. This means that if the device is audible, it will harm not rodents and pests, but the owner himself.
Conclusion: High-quality EcoSniper repellers operate in the range of 18-70 kHz (written in the instructions). This is quite enough to expel uninvited “guests”.

What to look for when choosing
To purchase a quality device, consider the following characteristics:
- radius of action;
- signal frequency;
- power supply;
- safety and comfort.
With range, everything is simple. You should purchase a repeller that is powerful enough to scare away mice and rats in your premises. Ultrasonic devices have the widest range of action: they can emit vibrations that can be heard within a range of up to 1000 square meters. But remember that manufacturers measure the range of their devices in empty rooms. As already mentioned, upholstered furniture, curtains, textiles, paper and soft objects will dampen ultrasound.
Now about the signal frequency. It must be at least 20 kHz. It's quite simple to check: if you hear a crackling or squeaking noise when you turn on the device, it means it's ineffective. Also, to purchase the best rat repeller, you need to consider the sound pressure. The optimal option is considered to be a pressure in the range of 110-130 decibels.
As for the power source , choose a device based on your needs. If you plan to repel rodents in areas without electricity, you should purchase a battery-powered device. As a rule, such devices have a shorter range than those that operate from the mains.
Of course, one cannot exclude such factors as safety and comfort. The best mouse repeller is the one whose operation does not interfere with you. Cheap devices can be noisy and cause headaches. They can also negatively affect pets. If you have decorative rodents in your home, it is better to get rid of rats and mice using another method.
Positive and negative!
There are a huge number of methods to combat cockroaches in an apartment. What is good and bad about this repeller? First, let's clarify about several types of such devices. The most effective are ultrasonic and electronic repellers.
- they are non-toxic;
- available compared to the disinfestation procedure;
- easy to use;
- effective in the fight against insects and rodents;
- suitable for use in small and large areas;
- no need to leave your living space.
- Ultrasonic and electromagnetic waves do not pass through walls, significantly reducing the radius of sound propagation.
- The device repels cockroaches, but does not kill them. That is, in the future the insects will return and then you will have to buy the device again. It turns out to be a vicious circle. As a result, the price of constant updating of the device can be equal to time-tested pest control.
There are advantages and disadvantages to using repellers. You can choose this device or use another method of struggle, depending on your preferences and goals.
Flaws
Does the device have any disadvantages? I would like to believe that it is not. But we all understand perfectly well that there are no ideal things.
There are many restrictions here:
- You cannot bathe an animal in the device;
- the device cannot be removed, you must walk in it constantly;
- The action begins, according to manufacturers, after 2-4 weeks.
The last one is the biggest drawback. If the device begins to operate only after such a long time, then the animal is left without protection from fleas. Accordingly, the use of other means is required - drops, suspensions, flea collars. These are additional expenses that the dog owner was trying to avoid.
From a health point of view, everything is also ambiguous. Some animals under the influence of ultrasound begin to behave restlessly or, on the contrary, become apathetic and stop playing. If we remember that prolonged exposure to ultrasound is detrimental to a living organism, then the recommendation to wear it without removing it begins to worry dog owners.
And the last drawback is the cost. A flea device with ultrasound is much more expensive than drops.
Environmental conditions
Fleas cannot tolerate certain conditions, the creation of which can lead to their disappearance. Like other insects, bloodsuckers are afraid of negative temperatures. Even a drop in air temperature to +10 degrees does not allow the “horses” to reproduce. This fear makes it possible to quickly defeat fleas in winter - you just need to let the frost get into the room. And if doing this with an apartment is somewhat difficult, then freezing a barn, a chicken coop or a separate summer kitchen is not at all difficult.
Fleas, their eggs and larvae
Fleas are afraid of water, so while bathing the animal, you can reduce the number of insects. To do this, you need to pour enough water into the bath so that the animal is completely covered. You can water your head from a ladle, avoiding getting water into your ears. The fleas will move to the remaining dry areas where they can be easily collected. The sun also repels fleas - bloodsuckers try to run away from an animal lying in the sun.
Instructions for use
The Ridex repeller looks like a rectangular white body with light indicators that signal a change in operating mode.
Attention. On Riddex, sometimes you need to switch electromagnetic pulse modes. This is a necessary measure that will help prevent pests from adapting to the action of the device, as well as increase its efficiency.
It is enough to connect Ridex to the network for it to start working
The pest repeller comes with instructions in Russian, which explain in detail how to use it:
- Open the package, connect the device to the network.
- Try to choose an outlet in an easily accessible location with low humidity. Make sure that it is not blocked by curtains, cabinets, or other furniture, and that heat sources (heating radiator or fireplace) are kept away from the switched on device.
- Immediately after connecting to the power source, a green light comes on, indicating that the repeller has started working.
- If the red light comes on, this means that electromagnetic waves have begun to spread throughout the area. Don't worry when the red light goes off. After a few minutes it will turn on again. The work cycle is constantly repeated.
- There is a button on top of the device, by pressing it you will turn on the backlight; it lights up in blue. At night it can be used instead of a night light.
- Ridex is suitable for continuous operation, that is, there is no need to turn it off, it does not overheat.
For a room whose area exceeds 180 m², it is recommended to use 2 devices. In this case, the repellers are connected to the network at the most remote ends of the house so that they cover the entire territory.
As a rule, it takes from 7 to 28 days to completely clear an area of pests. Mosquitoes that are most sensitive to Ridex ultrasonic waves disappear the fastest. Small rodents leave the house a little later - after about 20 days. The longest wait will be for the migration of cockroaches, which can last up to 4–6 weeks.
Important. You should not turn off the repeller during the first month of exposure, as the electromagnetic field will disappear and everything will have to start again. The device has an original design, thanks to which excessive power consumption or short circuit is excluded.
Do not rush to disconnect the device from the network even after the pests have completely disappeared. Leave it on for another 2 – 5 days to consolidate the results. Then the repeller can be connected periodically for several hours, 1 - 2 times a week, so that cockroaches or mice do not decide to come back.
Do not be alarmed if the pests become more active the first time after turning on the device. This indicates that they feel discomfort, which means they will soon begin to leave their home.
Do not wash the device with water, as its body is not sealed. Try to avoid dropping it because it is fragile.
Devices don’t have to be expensive, smartphone apps are also suitable
One myth and two misconceptions:
1. Cheap devices of the unknown. Yes, yes, that’s exactly what you can call boxes of 100 rubles. per piece, which are sold at every turn. A beautiful module with a light bulb will not protect against pests, and the alarm does not indicate whether ultrasound is working or not. The cheerful backlight means only one thing – the device is plugged into a power outlet or left without power.
EcoSniper certified ultrasonic repellers undergo multi-stage testing. Researchers are constantly working to improve characteristics and offer complex impact devices. These developments require money, which means that the devices cannot be cheap. To avoid buying an expensive fake, models are ordered on the company’s website. This will be a guarantee of quality.
2. Smartphone apps do not work as a repeller for mice, rats and other pests. You can check whether the ultrasound from the gadget works on mosquitoes and flies. You don’t even need to check this on dogs, it can all end in disaster.
Mobile gadgets are not designed to emit ultrasound waves of the required power. Any and all destruction programs and repellers are just an advertising gimmick. Even worse, such exposure can negatively affect the health of the user. Loud sounds cause nervous stress and negative emotions. Ultimately, the mice will feel great, and the owner of the program will suffer from a migraine.
Air temperature unacceptable for fleas
For normal existence and reproduction, certain conditions are required, namely +30, and not higher than +45 degrees. At -10 they stop reproducing, and at -15 they begin to look for a new shelter. Therefore, in winter they are frozen out from everywhere, wherever they are.
Fleas are also afraid of water, but only when there is a lot of it. In this case, they experience oxygen starvation, and accordingly, they begin to die en masse. When bathing cats and dogs, you probably noticed that fleas gradually begin to move from the body to the head. Therefore, it must be moistened generously and washed with shampoo, but at the same time, do not forget about the ears. To prevent water from getting in there, you can insert a little cotton wool into the animal’s ears.
Who are fleas?
Before you learn how to cure a bite and destroy the cause of its occurrence, you should understand who fleas are.
Fleas are parasitic insects whose bites are dangerous to humans and animals. Despite the fact that they are selective in choosing a host, they can nevertheless live and feed on the blood of not only humans, but also animals. Dog fleas, for example, prefer dogs, as well as foxes and wolves. These parasites are transmitted to humans from animals: cats, dogs and others; they are not only unpleasant, but also bite painfully.
It should be noted that there is a human flea that by nature feeds on blood. Such an insect cannot live long on a human body. Parasite bites are dangerous. They jump on people and bite them, after which they feed.
The human flea is quite large in size and reaches 3 millimeters in length. She can jump 50 centimeters in length. The body of these parasites has a laterally flattened shape. Fleas in humans easily move among hair, but they cannot live there for long, just like on the body of cats or dogs.
But, despite the fact that the flea is human, it can often be found in cats or dogs.
Human fleas, despite the fact that they look almost the same as other species, can be distinguished. This can only be done by an entomologist under a microscope. Parasites of this species look like small brown grains. They can be seen on the floor or body. They are very common in the hair on people's heads and can be confused with lice, but their bite is different. Fleas are more mobile and can jump.
Flea larvae are similar in appearance to fly eggs. They are white, small in size, and have a worm-shaped body.
Bites from adults are dangerous, regardless of the species: cat, human or dog, since they all feed on blood. They bite warm-blooded animals and humans. For most of their lives, parasites are found in secluded places where humans, cats and dogs are present. In such areas they multiply, larvae develop, the main food of which is: rotting organic remains and flea excrement. As soon as the fleas get hungry, they jump on a person, where, having pierced the skin with their proboscis, they begin to drink the blood of a person, cats and dogs, leaving a bite. Having had enough, the flea leaves the human body or animal.
The average lifespan of bloodsucking fleas is several months, however, the maximum flea can live is up to 1.5 years.
In addition to human fleas, the following can be transmitted to people: cat, dog, rat, and rabbit fleas. However, they all attack humans when their natural owners are not around. They bite humans as well as animals. Flea bites are dangerous because they transmit various diseases. Cat fleas are smaller than human fleas, but they are more common. Especially if the cat not only lives at home, but also goes for walks. Cat fleas often live in hallways and basements, so the animal can bring them into the house on itself. Accordingly, as soon as at least one bite is noticed on the animal’s body, you should carefully examine the pet and take action.
