Why are rodents in the countryside and in agriculture so harmful?
Many summer residents are faced with the problem of the spread of rodents. The harm they cause is obvious. If rodents are in your area, your plants will most likely suffer. You may be at risk of them eating the fruit. They are not only harmful to plants: a rat can also scare your animals. Needless to say, something or other equipment can be damaged by rodents.
These animals not only devour cultivated crops, but also spread diseases that are dangerous to humans. It is known that from these uninvited guests you can catch yersiniosis, salmonellosis, and rabies; rats can transmit tapeworms and even spread fever.
Vasily Rumyantsev, who holds a responsible position in a company that produces products to combat these pests, spoke about the dangers of rodents for agriculture: “They eat not only crops, but also food for animals and birds.” Therefore, it is important to try to prevent them from entering your territory.
Fighting methods
In order to combat pests, you can use several methods at once:
- Preventing site cleanliness;
- Breeding cats, dogs;
- Use of repellers, mousetraps;
- Plant processing;
- For large farms: use of a deratization system.
Below we will focus on such a control device as an ultrasonic mouse repeller. It can be used by owners of a wide variety of farms and plots.
What is this device?
Anyone who has not encountered the problem of rodent infestation may not be aware of this. However, if this problem has become urgent for you, it is important for you to consider the possibility of using a pest control method such as repellers.
Repellers available on the market can be divided into the following types:
- Ultrasonic;
- Electromagnetic;
- Combined.
Each type of repeller is characterized by its own way of influencing rodents. At the same time, the ultrasonic repeller has proven itself to be the most effective. How does it work?
So, an ultrasonic repeller is a device that produces ultrasonic waves to repel rats and mice. Such devices have appeared on the market relatively recently, and they have established themselves as a new method of pest control. According to user reviews, this tool can be very effective.
Expert opinion
Kuznetsov Vasily Stepanovich
How does this device work, and how can you use it to repel rats and mice? The basic principle of its operation is that it generates waves whose frequency is high enough to affect the body of rats and mice, thus causing them to panic. As a result, they strive to leave the room in which the ultrasound is propagating as quickly as possible.
Let us highlight the pros and cons that are identified by the owners of the devices and characterize their operation:
Pros:
- This device really works. Damage from rodents becomes less;
- There is quite a large selection of models on the market. There is an opportunity to find the right one for yourself;
Minuses:
- The device is very expensive;
- The effectiveness of different devices varies. There is a chance to run into one that works worse, or even a fake;
- The radius of wave propagation for most devices is not too large.
In the magazine “Agrotechnics and Technologies,” specialist Alena Drozdova outlines the following conditions for using such a device: “There should be no objects in the area where the repeller is installed that interfere with the passage of the beam. ... It is important to remember that ... their influence will be weaker the further they are from the repeller.” Repellers are very expensive, and therefore not everyone is ready to purchase them.
If you decide to buy an ultrasonic mouse repeller, read reviews about each of them. Not all models have proven themselves to be effective.
Types of repellers
The modern market provides a considerable number of types of rodent repellers. Ultrasonic mouse traps have different methods of action, power, design, and cost.
Popular types of rodent repellers are ultrasonic, electromagnetic, and combined devices. All devices are considered effective. But in practice, the most effective are ultrasonic traps for the home.
Some people try to make a mouse repeller with their own hands. However, for this you need to have the skills of a radio amateur. Therefore, it is easier to purchase a ready-made trap.
Ultrasonic devices
Ultrasonic devices for repelling rats and mice are considered the most effective. This has been confirmed by a number of studies.
The trap emits waves of various frequencies at high volume. While the repeller is operating, mice nearby begin to experience discomfort and leave the room.
How the ultrasonic mouse repeller works is written in the instructions for the device. The trap automatically changes frequency.
It is noteworthy that waves are absorbed by soft materials, and hard ones are reflected. For the scarecrow to work best, it must be placed in an empty room.
Mouse repellers are installed almost everywhere:
- industrial enterprises;
- apartments;
- attics;
- offices;
- basements;
- warehouses;
- garages;
- residential buildings.
The advantages of ultrasonic repellers are uninterrupted operation, relative safety, and environmental friendliness.
Disadvantages include the impediment of waves through walls and reduced efficiency in a cluttered room.
Electromagnetic devices
Modern electromagnetic mouse repellers operate by emitting impulses transmitted through electrical wires in the area where one counter is located. Such devices negatively affect the nervous system of pests.
But when the electrical device starts operating, the number of mice may increase. This is explained by the fact that the waves penetrate into voids and ceilings, which are favorite places for harmful animals. Experiencing discomfort, rodents leave their homes and begin to look for a way out.
Mains powered repellers are considered more powerful. Therefore, experts do not recommend choosing models that operate on batteries.
Advantages of electromagnetic traps:
- environmental friendliness;
- continuous operation;
- wide area of influence;
- safety.
Electromagnetic repellers do not change the operation of other mains-powered devices. The main advantage is that traps help get rid of mice hiding in walls and ceilings.
The disadvantage of electromagnetic repellers is that for the device to function properly, the wiring must be located along the length of the entire room.
Combined instruments
The combined repeller combines electric and ultrasonic methods of influencing mice and rats. As an additional effect, universal devices emit light signals.
Pests get used to one type of waves, and changing their type and frequency prevents this. Thus, a combined repeller is considered the best means for repelling mice.
Advantages of a multifunctional trap:
- quick effect;
- versatility;
- action in any type of premises;
- safety.
In order for the device to function properly and at high power, it is better to choose an ultrasonic mouse repeller that is not battery-powered, but one that runs on batteries.
The only drawback of the device is its high cost. But high efficiency, fast and extensive action make this minus insignificant.

Features of device operation
For the device to work truly effectively, it is important to use it correctly. Consider the following recommendations:
You cannot use ultrasonic mouse repellers and devices designed to attract them at the same time. This combination of opposing goals will lead to undesirable consequences. Repelling will lead to the fact that rodents will avoid traps, and luring will lead to the fact that they will still run into the enclosed room. As a result, you will not achieve an effective result.- Please note that the effect of ultrasound is limited. It does not spread through walls. “Therefore, the range of the device is limited by the room,” writes the portal Ivd.ru. Therefore, carefully consider the choice of the room in which the device will be installed if you are purchasing only one device. This room should be the place where most of the rats and mice that enter your home visit. Using devices in a nearby, less-trafficked room is not very effective or efficient. But there is another way of placement - you can purchase repellers for different rooms and install them in each. You also cannot expect that by installing the device in a separate building, you will get effective results from its operation in a nearby house.
If you live or are simply outside the city, then the most suitable place to place the repeller would be the basement.
- Take into account the characteristics of ultrasound propagation in the room. If there is not too much upholstered furniture or none at all, then there will be fewer problems: ultrasound will be reflected from the walls and, as a result, spread throughout the room. In the case of upholstered furniture, ultrasound is absorbed to a greater extent, and the effect of the device is minimal. Therefore, place indoors those objects that can lead to an infestation of rodents, precisely in the room where the conditions allow the repeller to work.
Keep in mind the following: placed objects may interfere with the repeller's operation by absorbing sound. Therefore, it is advisable to place several repellers in such a room. The author of the article tried to use one repeller in a room with shelving, but the range was not always enough. Therefore, it was necessary to place several such devices at once.
- Many summer residents have rooms in their homes without electricity. For such conditions in winter, they tried to purchase a special type of repeller: battery-powered. We strongly do not recommend taking such a step, since your batteries will simply freeze. In winter, outside the city, if you do not have electricity, try a car repeller: it can serve you for a long time.
- The repeller should only work when it is really necessary. Its operating principle is as follows: rodents that have chosen a particular room encounter the effect of ultrasound in it and begin to “associate” this room with such a stimulus. As a result, they begin to simply avoid him. When does this rule apply? Only if rats and mice have “alternative” places where they want to run. If there is no choice, then they learn to visit this room despite the presence of ultrasound. This can happen if the ultrasound is always on: if it works only for a while, then the rodents are afraid to encounter it again, and if it is constantly on, then they learn to ignore it.

How to choose a rat repellent device for a small, medium and large room?
Choose an ultrasonic rodent repeller based on your needs and the recommendations of those who have used this item. But what else should you consider and what should you pay attention to when choosing a repeller?
First, carefully read the characteristics of the repeller regarding ultrasound : the range of emitted high frequencies (if it captures frequencies up to 20 kHz, then you will hear it), constant change (by default or the ability to select a mode) of the frequency of the emitted wave, the angle of signal propagation ( the bigger, the better).
Secondly, consider the features of the room.
For example, if food , then rodents will not be quickly driven out. An ultrasonic rodent repeller can fight rodents for about two months. For comparison, in the absence of food and water, rodents will leave in about two weeks.
Third, remember about pets .
If you have pets at home, then know that repellers are safe and will not harm the animals or their hearing. But in cats, dogs and other pets like hamsters and guinea pigs, ultrasound may cause concern because... They have better hearing than people and they hear it. Keep this in mind and remove pets from the room where such a device is operating.
Fourthly, keep in mind that for rooms with different areas, repellers of different power and types of impact are needed . Therefore, pay attention to the declared coverage area of the device and compare it with yours. But remember that the packaging indicates the area of the empty room; accordingly, assess the degree of load with furniture and things in your apartment, house or office. Remember that repellers work best in empty and semi-empty rooms!

Choosing a rat and mouse repeller
How everything works
There are three types of rodent repellers:
- Ultrasonic.
- Electromagnetic.
- Combined.
Ultrasonic devices
Ultrasonic repellers generate high-frequency sound vibrations. This sound is not perceived by the human ear, but negatively affects the rodent’s nervous system, causing it to panic. To prevent mice and rats from getting used to the noise, the device constantly changes its frequency. Some models of ultrasonic repellers are equipped with light indicators: they generate chaotic flashes of light that blind pests and disorient them in space.
If we talk about the disadvantages of such devices, there are several of them:
- ultrasonic repellers can only work within the same room or area in which they are turned on, since ultrasound cannot pass through walls;
- upholstered furniture, curtains, textiles, as well as paper and soft objects reduce the effectiveness of the device because they absorb ultrasound.
Electromagnetic devices
Electromagnetic devices emit pulses that travel along wires within one electric meter. They negatively affect the nervous system of rodents, causing them to flee from danger. The first few days after turning on such a repeller, you will notice a sharp increase in pest activity: the fact is that impulses are transmitted along the walls, penetrating between ceilings and voids - exactly where mice and rats like to live. Because of this, they will leave their burrows and look for a new home.
Electromagnetic devices have a significant disadvantage. For them to work effectively, it is necessary that the wiring runs along the entire perimeter of your home, or at least along the longest wall. If this condition is not met, you will simply waste your money.
Combination devices
As the name implies, combined repellers combine two methods of harmful effects on rodents. These devices are universal and most effective.
We can say that the combined device is the best repeller of rats and mice.
