Mice and rats have long caused people many problems. These small rodents not only destroy a significant part of the peasants' harvest, damage things and buildings, but also spread diseases that are deadly to humans. And if earlier people had to fight with the help of traps or poison, today modern repellers come to the rescue. And even if they do not act instantly, the pests in full force leave the uncomfortable home. Most devices influence the psyche of rodents using ultrasonic or electromagnetic waves. A power source is required to bring the device into working position. Most often, the connection is made to a household power supply, but there are models that can operate from autonomous power sources, for example, a car battery. When choosing a repeller, experts recommend paying attention to several parameters.

Criteria for selecting rat and mouse repellers

1. Radius of action.
   One of the most important characteristics of an electronic defender is its range. Ultrasonic models are considered the most powerful; they produce acoustic waves that frighten pests over an area of ​​up to 1000 square meters. m. But the walls become an insurmountable obstacle to further spread. The range of action of electromagnetic emitters is more modest (up to 200 sq. m), however, due to branched electrical wiring, they form a uniform magnetic field in which both rodents and insects feel uncomfortable.
2. Signal frequency.
   The deterioration in the health of rodents is directly related to the strength of sound pressure. The optimal range is 110-130 dB. The weaker the impact, the longer the pests will stay indoors.
3. Power supply.
   When choosing a repeller for a remote warehouse or basement, it is better to give preference to devices with autonomous power supply. The signal strength and range may be reduced somewhat, but you won’t have to install a gas generator or lay a long electric cable along the street.
4. Safety and comfort.
   To operate in a residential area, the repeller requires operation that is silent and harmless to humans. Some models, when turned on for a long time, worsen the well-being of residents. You will also have to take care of your pets, since most devices make hamsters and guinea pigs restless.

Our review includes the best repellers for rodents and insects. When selecting applicants, the following criteria were taken into account:

1. efficiency of application;
2. radius of action;
3. type of radiation;
4. price;
5. expert opinion;
6. consumer reviews.

Manufacturers rating

Despite the fact that in a store you can even get confused by the variety of devices presented, devices from some manufacturers are justifiably popular, which is why most buyers choose them.

GRAD repellers have several emitters and have a stable effect. Tornado company offers devices that are installed in large non-residential premises: wells, tunnels and mines. Ecosniper devices perform best . They have a modest operating area, but in terms of sound pressure levels, almost all of the company’s devices remain leaders.

Rating of the best rat and mouse repellers of 2020. All devices presented in the rating are the best according to several criteria. Some have strong sound pressure, while others have a large area of ​​effect. And since different devices are required in the home and large premises, they are divided into two categories.

Comparison of ultrasonic and electromagnetic repellers

Features of device operation

For the device to work truly effectively, it is important to use it correctly. Consider the following recommendations:

1. 
   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.

2. 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.

1. 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.

1. 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.
2. 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 install the device correctly

The effectiveness of most repellers increases significantly in the presence of reflections of ultra-high frequency sound waves in the room. This is achieved due to the presence of hard surfaces and the absence of absorbent ones. So, the device will work perfectly in a room with a small amount of wooden furniture, and very poorly in a room with carpets, thick curtains and the presence of soft sofas and armchairs.

It is also necessary to provide escape routes for mice, otherwise they will simply have nowhere to escape from the constantly emitting unit.

Attractive poisons and rodent repellents are two mutually exclusive factors that people most often do not know about or forget about. Do not use repellers and baits at the same time! Do not leave food or its remains freely accessible to mice, this also applies to food waste; close the trash can and take out the waste on time. It is extremely important to limit pests’ access to water; make sure that your valves and taps are not leaking, and that there are no open containers with water.

Mice will always find food for themselves

The mouse repeller must work continuously until the pests are completely gone. After this, the device is periodically turned on for preventive purposes or when rodents reappear.

Follow safety rules. Ultrasonic repellers are powerful emitters and can be harmful to your health and the health of your pets. Constantly being in close proximity to the emitter can be very dangerous. Even the “silent” mode in a very high-quality device requires the latter to be located at least three meters from the person’s permanent location. It is especially dangerous to bring a working device to your ear - at a sound pressure of 120 decibels, even ultrasound can theoretically cause injury to the internal auditory organs!

The best ultrasonic rodent repellers (rodents only)

The easiest way to choose an ultrasonic repeller is for rodents such as mice, rats and moles. A certain frequency of radiation is adjusted to them, and other representatives of the animal world do not respond to the signal. Here are some effective rodent control devices.

Grad A-1000 PRO+

Rating: 4.9

Many flattering reviews can be read on thematic forums about the properties of the Grad A-1000 PRO+ repeller. Many users call it a real human protector from rodents and other small animals. The device has all the features of a rating winner. Take, for example, the temperature range (-35...+75°C), at which it instills fear in mice and rats. Therefore, you can install a repeller not only in the house, but also in cellars, sheds and garages.

But the most important advantage of the device is its large range of action (up to 1000 sq. m). The manufacturer has provided the ability to adjust the product depending on the desired impact. The repeller requires a household electrical outlet to operate, although it can also be connected to a car battery using terminals.

Advantages

• large range of action;
• four operating modes;
• works in both heat and cold;
• works from mains or battery.

Flaws

• not detected.

How to make an ultrasonic emitter with your own hands

Any person who is interested in radio engineering can assemble a simple rodent repeller. The heart of the device is the K131LA3 or K155LA3 logic chip.

The circuit uses the so-called TTL logic

The principle of operation of the circuit is based on the action of the oscillator DD1.3 and DD1.4 with a frequency of 100...400 Hz. These pulses are the control pulses to generate a higher frequency signal.

Table: required components for assembly

You can try other options for implementing output circuits.

Option 1.

Using an electrolytic capacitor

Option 2.

Without output capacitor

The assembled circuit does not require configuration and, as a rule, works immediately.

The best ultrasonic repellers of rodents, insects, animals

Often not only rodents, but also insects or stray dogs compete for a place in the sun next to a person. In this case, it is better to choose universal models. They operate in a wider range of frequencies, causing panic in the surrounding animal world. Experts noted several products.

Weitech WK-0600

Rating: 4.9

The Weitech WK-0600 repeller has the widest functionality. Experts note the reliable metal case, which cannot be damaged by small animals. Thanks to 9 modes, it is possible to clearly configure the device for a specific type of pest. These could be mice and rats, moles or cockroaches. The effectiveness of the impact is achieved through the use of two emitters. A unique signal alternation algorithm prevents pests from getting used to it, and the sound pressure level (116 dB) is enough to affect a radius of 325 square meters. m.

Users are satisfied with the high efficiency of the repeller, the presence of a large number of settings, and volume control. Pests leave the premises after 3 days of exposure, and complete disappearance is observed within 2 weeks.

Advantages

• high efficiency;
• versatility of use;
• wide functionality;
• durable body.

Flaws

• high price.

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.

The best electromagnetic mouse and rat repellers

In those buildings where there is an extensive electrical network, it would be best to resort to the help of electromagnetic repellers. By inserting the device into a socket, scaring impulses are generated along the entire highway. Insects and rodents leave niches in the walls or under the floor not only next to the operating device, but also in neighboring rooms. Experts liked the effectiveness of the following models.

EMR-21

Rating: 4.9

The main advantage of the Chinese electromagnetic repeller EMR-21 is its quality and efficiency. It surpasses its competitors in range (230 sq. m), which, combined with reliability, makes the device a winner in the rating. The device protects living quarters from a variety of pests, from rodents to cockroaches. When connected to a household electrical network, pulses are generated that propagate along the electrical wiring. They irritate pests, forcing them to leave the action area. At the same time, the repeller looks compact and stylish.

The repeller has a light indicator that allows you to determine the status of the device. For humans, electromagnetic radiation does not cause discomfort, but some pets (hamsters, guinea pigs) will find the signal annoying.

Advantages

• high-quality manufacturing;
• large range of action;
• effective protection;
• simple controls.

Flaws

• not detected.

Advantages of repellers

Compared to other methods of controlling rodents, repellers have characteristic advantages:

• safety : unlike toxic substances, the operation of ultrasonic and electromagnetic devices does not pose a serious danger to the health of humans and pets;
• absence of corpses : when using repellers, you do not have to deal with rodent carcasses;
• ease of use : just press one button, after which the device will turn on and start working.
