The ultrasonic repeller of rodents and insects is an electronic device that protects farm buildings, houses, warehouses, granaries, cottages and other buildings from rats, mice, insects and other small pests. It functions in different climatic conditions, is not dangerous for the health of people, animals, it requires little energy.
Modern weapons from pests
Currently, there are many places where it is not difficult to purchase an ultrasonic repeller for mice, insects and cockroaches. These devices are absolutely safe for people and the environment. In addition, they do not generate pain in animals, causing them only a sense of anxiety and discomfort.
When waves are emitted, physiological communication between individuals is disturbed, and feelings of danger and anxiety increase. The device is designed so that the oscillation frequency is constantly changing, otherwise the pests could adapt to the alarm signals and stop responding to them. If a dilemma arises, to purchase a device or to make an ultrasonic insect repeller yourself, it is recommended to opt for factory devices, which are presented in a wide assortment in stores at reasonable prices.
Features of ultrasonic repellers
These devices have the following features:
- The ultrasound generated by this device is reflected from almost any surface.
- Ultrasound does not penetrate walls and floors.
- The electromagnetic waves of the device do not pass through metal obstacles.
- The electromagnetic waves emitted by this device pass through walls.
- Many electronic devices emit only ultrasound.
- Repellers such as AR-130, UP-116-T, TM-9034 also emit electromagnetic waves.
Ultrasonic electronic insect and rodent repeller: principle of operation and installation
The operation of the device is based on the emission of ultrasonic waves delayed by obstacles. Objects from several rooms should be equipped with a number of devices equal to the number of rooms. For a small house and open space, one appliance will be enough. In warehouse buildings it is better to increase the density of installations, and in open spaces it is necessary to take into account the impact of natural factors.
Ultrasonic repellents of insects, cockroaches and rodents act in a radius of 0.8-3 meters and affect differently individual individuals.
Ultrasonic devices
Ultrasonic devices are currently the most effective devices that guarantee the elimination of annoying pests. Their advantage lies in the absence of the need for constant maintenance and in independent functioning throughout the season. It needs to be activated only once, and it will work all season even in the absence of owners, without requiring replacement of components.
The linear range of such devices includes electromagnetic models that are capable of creating very powerful electromagnetic pulses that cause a panic reaction in pests. They begin to refuse food and reproduction and soon leave the sphere where the device is installed. The device silently generates waves at varying frequencies, avoiding addiction. Within 2-4 weeks, the maximum effect is noticeable.
Ultrasound and Pets
You should be aware that electromagnetic repellers are dangerous for all pests, including domesticated ones, such as guinea pigs, rats, hamsters. The devices operate from the mains, spreading to all rooms where there is wiring. The device effectively acts on rodents and insects, including cockroaches, mosquitoes, fleas, bees, ants.
How to choose an ultrasonic repeller?
Ultrasonic repellents for insects and rodents are sold in specialized and online stores. When choosing, it is recommended to follow these rules:
- Carefully read what the ultrasonic repeller of rodents and insects has reviews, and get acquainted with the characteristics of the devices.
- Compare the area indicated on the repeller with your territory.
- The devices indicate the parameters of an empty room, so you need to correctly assess the workload of the house.
- It is necessary to take into account the purpose of the premises.
- The device fights pests for about 60 days. If there is no food in the room, they leave earlier (about 2 weeks).
- If you have pets at home, you need to use ultrasound, which is not audible to them. Foreign appliances are ideal.
- When buying several devices in different rooms, you should know that some of them work at low temperatures (Sonar, Spektr, Tornado).
Advantages and reviews
The ultrasonic repeller of rodents and insects, the reviews of which are the most positive, has the following advantages:
- simplicity in operation;
- insects and rodents go away;
- the effect becomes noticeable after 4-12 days;
- modern appliances work in almost any climate;
- minimal energy consumption;
- long service life;

- safe for people;
- convenient and economical method of influencing rodents and insects.
In addition, according to customer reviews, the device is quite compact and easy to maintain. Some models provide the ability to independently adjust the distance of exposure to the ultrasonic wave and frequency. The repeller works silently.
Popular models
The domestic market offers a wide selection of devices that differ in the area of impact, design, frequency, size and cost.
Currently popular are:
- Tornado 200 This ultrasonic insect repeller operates from the network, covering an area of 200 sq.m. It can be installed in cottages, garages, basements, warehouses. It works in a wide temperature range. The radiation frequency varies between 18-70 kHz, changing every five minutes. The weight of the device is 150 grams.
- Tornado 400 Its effect extends to 400 square meters. m. Weight is - 500 grams.
- Tornado 800 The device, identical to the previous models, has a working area of 400 square meters. m
You should also highlight such models as Chiston, Tsunami, WK, Grad A-500, Spectrum, Typhoon, Thunder, etc.
DIY repellers
If you have certain knowledge and skills in the field of electronics, an ultrasonic insect repeller can be assembled with your own hands. There are many different schemes. The simplest of them is based on an asymmetric multivibrator. The repeller consists of:
- 2 transistors;
- 3 resistors;
- 1 capacitor;
- circuit breaker;
- battery type "Crohn";
- piezo emitter (suitable for watches).
The dimensions of the device are quite compact, it can easily fit in a shirt pocket. The device operates within a radius of 1.5 m.
Ultrasonic scarers "Tornado"
The scheme of these devices is based on a special generator with auto-tuning frequencies, which eliminates the possibility of addiction of insects and rodents to sound. It is mainly used in large areas.
It is installed by the front panel to the habitats of pests. The ultrasound that the device generates is reflected off the walls and ceiling, filling the entire room.
This ultrasonic insect repeller has several advantages:
- small sizes;
- humanity in relation to pests and lack of unsanitary conditions;
- use in rooms of any area;
- highly effective in pest control;
