The ultrasonic rodent and insect repeller is an electronic device that protects outbuildings, 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 he alth of people, animals, requires little energy.
Modern pest control
Currently, there are many places where you can easily get an ultrasonic mouse, insect and cockroach repeller. These devices are absolutely safe for people and the environment. In addition, they do not generate pain in animals, causing them only a feeling of anxiety and discomfort.
When waves are emitted, physiological communication between individuals is disrupted, a sense of danger and anxiety increases. The device is made so thatthe oscillation frequency is constantly changing, otherwise pests could adapt to alarm signals and stop responding to them. If a dilemma arises, whether to purchase an installation or make an ultrasonic insect repeller with your own hands, it is recommended to opt for factory-made devices, presented in a wide range 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.
- Electromagnetic waves emitted by this device travel 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: working principle and installation
The operation of the device is based on the radiation of ultrasonic waves that are delayed by obstacles. Objects with several rooms should be equipped with the number of devices equal to the number of rooms. For a small house and open space, one device will be enough. In warehouse buildings it is better to increase the density of installations, and in open spaces it is necessarytake into account the impact of natural factors.
Ultrasonic insect, cockroach and rodent repellers operate within a radius of 0.8-3 meters and affect individual individuals differently.
Ultrasonic devices
Ultrasonic devices are currently the most effective devices that guarantee getting rid of annoying pests. Their advantage lies in the absence of the need for constant maintenance and independent operation throughout the season. It only needs to be activated once, and it will work all season even in the absence of owners, without requiring replacement of components.
The line of such devices includes electromagnetic models that are capable of creating very powerful electromagnetic impulses 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 changing frequencies, not allowing addiction. Within 2-4 weeks, the maximum effect is noticeable.
Ultrasound and pets
You should know that electromagnetic repellers are dangerous for all pests, including domesticated ones, such as guinea pigs, rats, hamsters. The devices operate from the mains, spreading throughout all rooms where there is wiring. The device is effective against rodents and insects, including cockroaches, mosquitoes, fleas, bees, ants.
How to choose an ultrasonic repeller?
Ultrasonic repellers for insects and rodents are sold in specialized and online stores. When choosing, it is recommended to follow these rules:
- Carefully read what reviews the ultrasonic rodent and insect repeller has, and get acquainted with the characteristics of the devices.
- Compare the area indicated on the repeller with your territory.
- The parameters of an empty room are indicated on the devices, so it is necessary to correctly assess the workload at home.
- It is necessary to take into account the purpose of the premises.
- The device fights pests for approximately 60 days. If there is no food in the room, they leave earlier (about 2 weeks).
- If there are pets in the room, you need to use ultrasound, which is not audible to them. Foreign appliances are ideal.
- When buying several devices in different rooms, you should be aware that some of them work even at low temperatures (Sonar, Spectrum, Tornado).
Pros and Reviews
Ultrasonic rodent and insect repeller, reviews of which are the most positive, has the following advantages:
- easy to operate;

In addition, according to customer reviews, the device is quite compact and easy to clean. Some models provide the ability to independently adjust the distance of exposure to ultrasonic waves and frequency. The repeller works silently.
Popular models
The domestic market offers a wide range of such devices, which differ in the impact zone, design, frequency, size and cost.
Currently popular:
- "Tornado-200". This ultrasonic insect repeller operates from the network, covering an area of 200 sq.m. Can be installed in cottages, garages, basements, warehouses. Operates over a wide temperature range. The radiation frequency varies within 18-70 kHz, changing every five minutes. The weight of the device is 150 grams.
- "Tornado-400". Its action extends up to 400 sq. m. Weight is - 500 grams.
- "Tornado-800". The device, identical to previous models, has a working area of 400 square meters. m.
You should also highlight such models as "Chiston", "Tsunami", "WK", "Grad A-500", "Spektr", "Typhoon", "Thunder", etc.
Do-it-yourself scarers
If you have certain knowledge and skills in the field of electronicsyou can assemble an ultrasonic insect repeller with your own hands. There are many different schemes. The simplest of them is built on the basis of an asymmetric multivibrator. The repeller consists of:
- 2 transistors;
- 3 resistors;
- 1 Capacitor;
- switch;
- Crown-type battery;
- piezo emitter (suitable from a watch).
The size of the device is quite compact, it can easily fit in a shirt pocket. The device operates within a radius of 1.5 m.
Ultrasonic repellers "Tornado"
The scheme of these devices is based on a special generator with auto-tuning of frequencies, which excludes the possibility of insects and rodents getting used to the sound. Mainly used in large areas.
It is installed with the front panel towards pest habitats. The ultrasound generated by the device bounces off the walls and ceiling, filling the entire room.
This ultrasonic insect repeller has a number of advantages:
- small sizes;
- humanity in relation to pests and lack of unsanitary conditions;
- use in rooms of any size;
