Insect repeller ultrasound with their own hands. Ultrasonic repeller rodents and insects: reviews

Ultrasonic repeller rodents and insects is an electronic device that protects farm buildings, houses, warehouses, granaries, cottages and other structures from rats, mice, insects and other small pests. It functions in different climatic conditions, is not dangerous for people's health, animals, requires little energy.

Modern weapons against pests

At present, there are many places where it is not difficult to get an ultrasound repeller of 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 radiation waves disturb the physiological communication between individuals, there is a growing sense of danger and anxiety. The device is made so that the oscillation frequency is constantly changing, otherwise the pests could adapt to the alarms and stop responding to them. If a dilemma arises, purchase an installation or make an ultrasonic repeller of insects with your own hands, then it is recommended to opt for factory devices, presented in a wide range of shops at reasonable prices.

Features of ultrasonic repellers

These devices are characterized by the following features:

1. The ultrasound generated by this device is reflected from almost any surface.
2. Ultrasound does not penetrate walls and floor.
3. Electromagnetic waves of the device do not pass through metal obstacles.
4. Electromagnetic waves emitted by this device pass through the walls.
5. Many electronic devices emit only ultrasound.
6. Such repellers as AR-130, UP-116-T, TM-9034, also emit electromagnetic waves.

Ultrasonic electronic repeller of insects and rodents: the principle of operation and installation

The operation of the device is based on the emission of ultrasonic waves delayed by obstructions. Objects from 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 suffice. In warehouse buildings it is better to increase the density of installations, and in open spaces it is necessary to take into account the influence of natural factors.

Ultrasonic scarers of insects, cockroaches and rodents operate within a radius of 0.8-3 meters and affect differently on individual individuals.

Ultrasonic devices

Ultrasound devices at the present time are the most effective devices, ensuring the disposal of importunate pests. Their advantage lies in the lack of the need for constant maintenance and in independent operation throughout the whole season. It needs to be activated only once, and it will work all season even if there are no owners, without requiring replacement parts.

The linear series of such devices includes electromagnetic models that are capable of creating very powerful electromagnetic pulses, causing a panic reaction in pests. They begin to refuse food and reproduction and soon leave the sphere where the device is installed. The device generates noiselessly waves at varying frequencies, avoiding addiction. Within 2-4 weeks, the maximum effect is noticeable.

Ultrasound and pets

It should be noted that electromagnetic repellents are dangerous for all pests, including domesticated ones, such as guinea pigs, rats, hamsters. Devices operate from the power grid, spreading across 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 scarers for insects and rodents are sold in specialized and online stores. When choosing it is recommended to follow such rules:

1. Carefully read what ultrasound rodent and insect repeller reviews have, and get acquainted with the characteristics of the instruments.
2. To compare the area indicated on the repeller with its territory.
3. The instruments indicate the parameters of the empty room, so you need to correctly assess the workload of the house.
4. It is necessary to take the appointment of the premises into account.
5. The device fights with pests about 60 days. If there is no food in the room, they leave earlier (about 2 weeks).
6. If you have pets in the room you need to use ultrasound, which is not heard for them. Ideal for foreign instruments.
7. When buying several devices in different rooms, you should know that some of them work at low temperatures (Sonar, Spectrum, Tornado).

Advantages and feedback

Ultrasonic repeller rodents and insects, reviews about which are the most positive, has the following advantages:

• Simplicity in operation;
