A private house and courtyard buildings become a refuge for unpleasant “neighbors.” Mice and rats spoil food supplies, scare poultry and never disdain chicks. The poison does not always cope with its task, as it can cause the death of pets. We propose to consider the best repellers, which we chose based on user reviews.
How does an ultrasonic repeller work?
Typically, an ultrasonic repeller is connected to a 220 V outlet, but there are models that are connected to a rechargeable battery or run on regular batteries.
When turned on, the ultrasonic repeller begins to distribute ultrasonic waves with a frequency of 1 GHz, which affect rodents. For rodents, this is a real sound attack that strains their nerves to the limit. And they have only one thing left to do, leave the place of discomfort.
But this effect is achieved by continuous operation of the device for 2-4 weeks.
Today, ultrasonic repellent is the most humane method of combating rodents that cause significant material damage to humans.
It is also important to know that ultrasound does not pass through solid barriers: walls, doors and closed windows. Ultrasound is absorbed or attenuated by products made of soft materials: carpets, upholstered furniture, curtains.
Therefore, in such places, one ultrasonic repeller may not be enough, and in order to cover the entire area of the room, you need to install a more powerful device or use several ultrasonic repellers. For a full guarantee, in such rooms the coverage area of the device declared by the manufacturer must be divided by 3 or 4, for more effective repelling of rodents.
Therefore, in our review of the best ultrasonic repellers of mice, rats and various rodents, we selected more powerful devices, taking into account the domestic use of these devices.

What do special studies say about the effectiveness of ultrasound against rats?
The results of several practical experiments on “wild” basement rats are known. The essence of the experiments was as follows:
- In one of the rooms of an abandoned building infested with rats, rat traps were installed with bait, but with the brackets removed. These rat traps did not kill the animals or even catch them, but made it possible to record the fact that a rat approached the bait. The rat trap worked, which means the animal was definitely approaching it;
- First, the number of rat traps triggered in the absence of the device was recorded;
- Then the test repeller was turned on in the room for the whole night, and the next morning the number of activated rat traps was assessed.
The more effective the repeller was, the fewer rat traps were triggered when the device was operating compared to the period without the repeller (the rats ran around the room less).
In such experiments, many devices were tested, and based on the results, it became clear that there are both quite effective professional products on the market and outright fakes that do not repel rats at all. When some devices were operating, the rats did not approach the baits at all, while near other devices they calmly fed and went about their “own business.”
On a note
In laboratory studies, it was found that rats, constantly exposed to ultrasound and unable to hide from the signals, were in a state of continuous stress, refused to eat and died after some time.
Here are just some of the fairly well-proven ultrasonic rodent repellers:
- Bioguard;
- Chiston-2;
- Chiston-2 PRO;
- TM-315;
- WK-0600;
- UZU-03;
- Range;
- Tornado-800.
Review
“To be honest, I was afraid to turn on the ultrasound in the chicken coop. I even thought about ordering a special safe trap to catch the rats. But then I took a risk. And it’s normal, the chickens didn’t seem to hear anything at all. And the rats disappeared, I haven’t seen them for a month now...”

Ultrasound in the life of rodents
Let's start with the fact that ultrasound refers to sound vibrations with a frequency above 20,000 Hz, that is, above the hearing threshold of the average person. Humans cannot hear ultrasounds, but many other animals perceive them quite normally.
On a note
Only a very few, especially sensitive people, are able to hear sound with a frequency just above 20 kHz. Such high-pitched sounds are perceived as a very thin, barely audible squeak.
The gray rat can perceive sounds with a frequency of up to 40 kHz, the house mouse - up to 100 kHz. That is, what is absolutely inaudible for humans is important sound information for these animals.
What is useful to know about ultrasound:
- The nature of ultrasound is no different from the nature of other sounds, which means it has the same characteristics: volume (power), directionality, ability to be reflected and absorbed. A small ultrasonic repeller, powered by a small AA battery, a priori cannot generate powerful ultrasonic radiation, and loud advertising statements about the amazing effectiveness of such “babies” in areas of several hundred square meters can only cause a smile;
- Any sounds, including ultrasound, can convey different information to an animal - neutral, unpleasant, frightening (a message about danger). That is, not every ultrasound will scare a rat, just as people do not attach significance to every sound;
- Rats, mice and other rodents actively use ultrasound for communication - for example, they use it to transmit signals of help or danger to each other.
This is interesting
Guinea pigs are one of the most vocal among rodents; they scream often and loudly in the ultrasonic range (inaudible to humans). The most silent are mice; they use ultrasound only in danger or in stressful moments (for example, during fights). Male mice also “sing” in the ultrasonic range, attracting females. The complexity of their songs is similar to that of birds. Interestingly, newborn rodent cubs actively communicate with their mother using the language of ultrasound.
All this means that it is technically possible to create a device that will generate ultrasound that creates discomfort or anxiety for rodents. Animals will avoid places where they hear such sounds, and therefore an entire room can be protected from them.
And the first thing you need to know to obtain such an effect is the optimal frequencies at which the corresponding ultrasonic installation should operate.
What in practice?
In real working conditions (for example, in a granary), a good device will almost instantly cause rats and mice to run away from the place where the repeller is turned on. When testing on laboratory mice, it is noted that they begin to rush around the cage, run to the farthest corner, throw food, and try to hide.
The practice of using ultrasonic devices shows that in many cases, when these devices are operating, rats stop entering protected premises or leave them if they previously lived in them permanently. But this is only relevant for effective devices, provided they are used correctly.
Choosing an effective device
According to the test results and taking into account the feedback of experts, the following models, for example, are quite reliable ultrasonic agents for rats and mice:
- Chiston-2 PRO - its price is approximately 3000 rubles, frequency range 20-70 kHz, protected area 450 sq. m;
- Bioguard - price about 4,500 rubles, protected area 850 sq. m;
- Chiston-2 - costs approximately 2,500 rubles, protected area is 300 square meters. m;
- Tornado-800 - price about 3,500 rubles, protected area 800 sq. m;
- TM-315 - 6500 rubles, protected area 750 sq. m.
Also, in many cases, WK-0600, Elektrokot and other devices with comparable technical characteristics turned out to be effective.
Review
“I became interested in the question when a huge number of rats were discovered at the dacha. I read in magazines about an electric cat, this thing costs 2000 rubles. Working area 200 squares. I don’t know how the rats felt there, but standing with the electric cat turned on bothered me, as there was an unpleasant squeaking sound. The rats are gone, but the sensations from the device are ambiguous, the squeaking is very unpleasant...”

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.

Requirements for the device itself
The mouse repeller will not always do its job well. To ensure that no problems arise during its operation, you need to check the device for compliance with the specified requirements.
Required conditions:
- sound pressure – more than 100 dB; wave propagation area – 360°; wave frequency should vary over a wide range; impact area should slightly exceed the area of the room.
Recommendation! If a device does not meet one of the requirements, it is not worth using.
