What are rat and mouse repellers? The operating principle of the devices, which one is better to buy

Rodents are omnivorous and ubiquitous; they can live in an apartment, house, barn, and even a car. They easily adapt to circumstances: comfortable conditions, their absence. The population actively reproduces regardless of environmental conditions. Each mature female is capable of producing abundant offspring: 5-15 cubs 5-6 times a year. Don't know how to deal with an annoying neighbor? You can get a cat, set mousetraps, use poisons and chemicals. However, it is safer and more effective to buy a repeller against rats and mice; let’s try to figure out which one is better.

Types and principle of operation of rat and mouse repellers

There is a special repellent device that causes high-frequency vibrations that irritate the nervous system and disrupt the functioning of rodents.

• creatures stop sleeping, eating, experience anxiety, and other psychosomatic disorders;
• Some devices are so strong that rodents may experience physical pain from the effects.

The repeller is effective not only for rats and mice. There are devices with a wide spectrum of action that can stop the invasion of moles and other animals, and drive away insects and birds. How to choose the best and most effective device that expels rodents and other pests? To do this, first consider what types of models exist.

By type of impact there are:

• ultrasonic;
• electromagnetic;
• combined.

Operating by type of power source:

• battery operated;
• from the mains;
• solar powered;
• combined.

Ultrasonic

Ultrasound was invented a long time ago, but it began to be used as a panacea for rats and other pests relatively recently. How does an ultrasonic rodent repeller work:

• 1) the human ear does not perceive ultrasonic frequencies, but animals hear, but react to the sound signal depending on its frequency;
• 2) if you set the bioguard to vibrations of 20-70 kHz, this causes panic in individuals and forces them to leave the territory.

Ultrasound generators that can be adjusted and changed the sound frequency are considered effective. This eliminates the possibility of animals adapting to constantly changing conditions. The device operates over a distance of approximately 50 m2, but if there are obstacles, you will need several pieces. Any obstacles cause wave attenuation, which must be taken into account during installation.

How to use the device:

• the ultrasonic rat and mouse repeller is placed on a stool, a chair 1.4-1.5 m high, placed in the center of the room;
• connect to a 220 V power supply network, leave for a day for the first time;
• after a day - turn it off, take a break for 10-12 hours, then turn it on again until the pests completely disappear (this happens approximately 14-21 days);
• To consolidate the effect or for the purpose of prevention, the wave apparatus is turned on every 7-8 days for 11-12 hours.

Electromagnetic

Repellers of rats and mice of this type are similar to the previous ones, they differ only in that they induce waves of a different type, namely magnetic pulses. They create a powerful electromagnetic field, within the boundaries, which rodents simply cannot exist. For humans and pets, the electronic repeller is absolutely harmless, and thanks to it, pests disappear after 10-15 days.

In the first days of operation of the device, hyperactivity of rodents may be observed, but after 2-4 days the process will begin to fade until the pests completely disappear. The electromagnetic device for repelling mice, rats, and other rodents is very powerful, affecting an area of ​​up to 200 m2.

Combined

The universal mouse and rat repeller combines the effectiveness and functionality of the devices described above. Simultaneously generates ultra sound and electromagnetic waves. This does not give rodents a chance to adapt and forces them to retreat and leave the territory forever. Ultrasonic and electromagnetic rodent repeller is also suitable for driving away harmful insects.

Power type

The bioguard can operate from a household power supply network, batteries or accumulator, or solar panels. There are universal models that operate on mains power, batteries, and, if necessary, solar power batteries. For the home, the best option would be an electric repeller powered from the mains. If you need to process a vegetable garden, barn, or large farmland, it is better to buy a battery-powered device.

How to choose a good repeller

Choosing a device that can get rid of household pests will be easier if you first study the primary characteristics that you need to pay attention to.

Types of rat and mouse repellers. Experts distinguish 3 types of such devices:

• Ultrasonic repellers emitting sound waves in a noiseless range for humans above 20 kHz.
• Noise , operating in a wide range that a person can hear (from 15 Hz), as well as silent (more than 20 kHz).
• Combined ones allow you to change the mode depending on operating conditions.

IMPORTANT. Ultrasonic devices work best in small spaces, as they involve the reflection of sounds from hard surfaces. On the street, the efficiency is much lower.

• Sound pressure. Another important criterion, the usefulness of which was determined by American scientists in the 40s of the last century. They found that sound pressure below 98 dB is not a serious irritant for rodents. Accordingly, the higher this indicator, the faster the device can cope with pests.
• Wave frequency. Rodents communicate with each other in the audio frequency range from 30 to 50 kHz. In general, they are capable of perceiving waves from 500 Hz to 70 kHz. In this regard, the best repeller is considered to be one that is capable of operating in a wider frequency range.
• Action area. When choosing a device, you should definitely pay attention to this characteristic, since a repeller that emits ultrasound in an apartment area will be useless in a large house or an entire garden plot. However, the more impressive the operating area, the more expensive the device is.
• Additional functions. Not everyone can manage with ultrasound alone in the fight against rodents. In some cases, additional device functions will be needed, such as flashes of light, electromagnetic radiation, or the ability to reproduce sound in the audible range.

REFERENCE. After considering all the criteria, we can conclude that the ideal repeller should operate in a wide frequency range, be able to propagate waves 360 degrees, have high sound pressure and match the area of ​​the room or area where it is planned to be used.

Advantages and disadvantages

What is the best rat and mouse repeller? This depends on the scale of the population, the location of the rodents, whether traps and rodenticides are used in parallel, how powerful the device is, whether there are any obstacles in the path of the sound beam, etc. The best devices are considered to be Grad, Tornado, Typhoon, ElectroKot, Chiston, Sniper, Pest Reject, etc. Each of them has positive characteristics, such as:

• power sufficient to quickly expel pests, a wide range of variable frequencies, which eliminates the possibility of adaptation to ultrasound;
• autonomy thanks to replaceable batteries and solar panels;
• operate from power supply networks of various ratings;
• have a built-in battery for uninterrupted operation in case of emergency power outage, in offline mode;
• emitters operate silently, without creating an irritating, distracting background;
• directly, through the cigarette lighter connector, connected to a 12V car battery;
• To cover the maximum area of ​​influence, they are equipped with several pulse generators.

Could the device not work efficiently?

When studying the ratings of the most popular rodent repellers and reading reviews, you may come across user complaints. They say the devices are not as effective as stated by the manufacturers. This is a fundamentally wrong point of view and here's why:

• Regardless of which mouse and rat repeller you choose, use only it. Remove poisonous baits and anything that can attract individuals while the emitter is operating. Poisoned complementary foods have a distinct odor that attracts pests. They run towards it, overcoming the discomfort caused by ultrasound and electromagnetic waves.
• Using the device, remove objects that level the waves. If ultrasound is absorbed by carpets, furniture, partitions, what efficiency of the device can we talk about?
• Operating rules are not followed. If the manufacturer recommends turning off the device after 3 weeks, follow the instructions.
• The product was purchased on a spontaneous market, or it does not have documents, user instructions, or a warranty card.

How does the repeller work?

Many people call this device an ultrasonic mousetrap, but this is not entirely true. Ultrasound does work against rodents, but mice and rats do not die. There will be no unpleasant odor from animal corpses in the house or on the property. There is no need to open the floor to get out foul-smelling carcasses; even in a locked room, the animal remains alive, while experiencing panic fear. At the first opportunity it will leave the dangerous space. This device compares favorably with poisonous agents against mice and other living creatures. The person has absolutely no contact with four-legged tenants. The risk of contracting infections carried by rats and mice is minimal.

Typhoon

A series of ultrasonic devices for home and car with the ability to customize operating parameters. They are distinguished by a wide emitter beam, operate from the network, and use energy resources economically. They operate in 2 modes (sound and silent), the vibrations change automatically after a specified period of time. They turn on at maximum if there are no people in the room, at minimum when there are occupants in the house. During operation, the devices are aimed at hard surfaces that reflect waves well. Can be mounted on the wall.

How to use an electric mouse repeller correctly

Manufacturers claim that all you have to do is plug a plug into a socket and the rodent repellent device is already in effect. This is true, but when placing the device you need to take into account some features:

1. It is better to install an ultrasonic rodent repellent device in a hallway or other room where a person spends little time. Despite assurances of complete safety, there is simply no need to stay near the ultrasound emitter for a long time to prevent rodents.
2. The direction of the emitter must be such that the coverage covers the entire house or garden.
3. The device must be placed above the ground, in the house no closer than a meter from the floor.

You need to remember the properties of sound propagation. Ultrasound repeller is no exception; it obeys the usual laws of physics. On the back side of the device, the effect of the device against mice and rats will be minimal, on the side where there are holes through which ultrasound comes out, it will be maximum.

Weitech

Devices powered from a 220V network consume energy economically. They generate ultrasound waves with a frequency of 20 kHz and higher. The line includes models for domestic needs, samples for large industrial and civil facilities. They have built-in light indicators. For the first 15-20 days, the devices should function almost continuously. Every 3 days they are turned off for 1-2 hours. Then, for prevention, it is enough to do this at night. EcoSniper Ultrasound and combined devices, some equipped with an additional air ionization function, can be used as night lights. Economical, powered from a 220V network, silent, equipped with an indicator. The instrument generator switches frequencies automatically. Suitable for apartments, houses, shops, warehouses, offices. There are models for vehicles.

There are 4 modes - ultrasound + sound, LEDs generate bright light flashes. The impact area of ​​the most powerful devices is up to 1000 m2. They are used in everyday life, in warehouses, hangars, institutions, and large industrial facilities. Electric Kot Bioguards operate on a 220V network, are economical, have day-night modes, and a set of other functions. They generate sounds with a frequency of 110 dB, the range of reproduced frequencies is from 30,000 Hz. Depending on the model, the coverage area is 200-400 m2.

The above rating is not able to cover the entire range of models offered by manufacturers, in particular by our online store.
The catalog of the site vse-otpugivately.ru presents all kinds of devices, different in the method of influence, power, and other parameters. Each electronic mouse and rat repeller device has its own advantages and some features. They must be taken into account before purchasing. If you find it difficult to choose, call toll-free 8 (800) 100-28-25, we will recommend the best options. You can also buy rodenticides, dog and bird repellents, mosquito and fly killers and much more from us. The great thing is that what mice are afraid of, people may not even notice. This fully applies to ultrasound, which we will never hear, but it will frighten rodents more than cats. Electronic repellers are becoming increasingly popular due to their safety and effectiveness. However, the number of models available on the market amounts to dozens, and the description of each device will indicate the significant advantages of this particular product. The best repeller is the same as the best car or day of the year. Everyone has their own and preferences depend on many factors. Let's briefly but informatively consider the essence of choosing a device wisely for two common use cases: at home or at work.

How much does an ultrasonic rodent repeller cost?

The price depends on the model, manufacturer and power. You can find a rodent repeller from 1000 to 3000 rubles. There are models that are somewhat more expensive, and there are very cheap miniature ones. Online stores sell devices for repelling rodents and insects. As often happens, attempts to make a universal device lead to the fact that both functions work poorly.

Some of the manufacturers managed to achieve good results. Determining whether a device works or not at home is quite difficult. The instructions often indicate that if the indicator light or LED lights up, then the device is already in operation.

Unfortunately, fakes do not have an emitter or produce a different frequency that does not solve any problems. An ultrasonic rat repeller will be of no use at all if it is purchased from a dubious seller and the manufacturer does not inspire confidence. It is better to choose a reputable manufacturer that has proven itself well in the market. Usually these are companies that produce infrared heaters, air humidifiers, and ionizers. If your home has such household appliances and you are quite satisfied with their quality, choose a rodent repellent device from this manufacturer.

What is the best rat and mouse repeller for a private house, apartment, or cottage?

In this case, the following points will be critical for repelling with ultrasound:

1. The total area of ​​the zone where there should be no rodents is relatively small and usually does not exceed 100-150 m2.

2. There are many separate rooms in the room, and there are relatively many different objects in them.

3. A person often stays indoors.

These nuances significantly influence the selection of a product and taking them into account, we recommend starting from the following criteria:

1.The operating area of ​​the device is not the main parameter

. In such rooms there are too many things that interfere with the propagation of ultrasound. It is better to stay with Tornado 200 (200 m2 of action) than with Typhoon LS-800 (1,000 m2).

2.The more devices you use, the better.

. In an apartment, you need to create the most uniform field of ultrasound repelling, and this is much easier to achieve with several devices than with one, but powerful one. Most often, a couple of Tornado 100 (M) (100 m2 of repellent), placed in different rooms, will be more effective than one Tornado 200.

What mice and rats are guaranteed to be afraid of under any circumstances is the correct installation of an ultrasonic repeller in a room.

Ultrasonic rodent repellers: operating principle

The operating frequency of most ultrasonic mouse and other animal repellers is from 21 to 44 kHz. This sound range is significantly higher than the human ear can hear. The fact is that the hearing aid of all species of animals and humans is structured similarly, but there are still significant differences. So bats “work” at a frequency of 40-100 kHz, mice hear 40-50 kHz, rats 30-40 kHz. Considering this, we can conclude that an ultrasonic mouse repeller will have a bad effect on rats if the frequency is designed only for small animals. Before buying such a device, experts advise checking the frequency range, power and looking at customer reviews.
