Bear Scarer

The bear repeller is actively advertised on sites on the Internet, promising a quick deliverance of a large area from harmful insects. A small device operates on the basis of high-frequency ultrasound, operates on solar panels, electricity, or conventional batteries.

Features of the device

Manufacturers offer a wide range of products with a deterring effect:

• Repeller Medvedok solar-powered. Provides for continuous operation with a service life of about 4 years.The battery charges independently. It is possible to insert conventional batteries. The device emits high-frequency waves that can cover an area up to 750 m, a depth of more than 2 m.
  

  On a note!

  A striking representative of this category of products is the STAGE B44 REPELER mole repeller from Canadian manufacturers. To get started, you need to install the device from Bears on a plot of land. It works in any lighting, different temperatures. The effectiveness is not affected by obstacles in the form of buildings, walls, stones in the soil. The weight of the device is about 400 g.

• Electronic repellers Medvedok. Less popular, as it is problematic to use in an open area. It is necessary to provide additional safe working conditions. The principle of operation is no different. There are several modes to prevent pests from adapting to vibrations.

Tornado Repellers

A prominent representative of this category of products is a device of domestic production - Tornado. Powerful ultrasound bypasses obstacles, penetrates the ground. Positive feedback on this device was left by users regarding rodent control.Universal remedy that acts with the same frequency on animals, insects.

The ultrasonic repeller of the bear should act on the organs of touch. Insects feel uncomfortable, leave their burrows, move to more favorable areas.

Features of the bear

What insects hear is beyond doubt. In the evening you can hear the melodious trills of a male singing songs for females. Adults crawl out, fly to meet fateby following the sound. However, an important role is played by how exactly insects hear. Bears do not perceive the sound, but catch the vibrations of a certain frequency with their whiskers.

On a note!

Scientists could not repeat the exact frequency of vibration of the sound that publishes a male. If it succeeded, the problem of fighting with the bears solved without special efforts.

Bear Scarer

It is theoretically possible to fight with Medvedka with ultrasound. Practically - the device is absolutely useless. The frequency published by him is designed for animals and insects. While every living creature publishes and catches a special range. Ultrasonic repeller loses the power of action, bumping into obstacles. Does not penetrate deep into the ground.Reverse claims from manufacturers are a marketing gimmick. Therefore, with a higher efficiency, it is recommended to use other funds from the bear in the garden.

Reviews

Led on advertising, an easy version of the fight. I bought a solar battery repeller. The result is zero. But cats avoided.

Marina, Moscow

Repellers performed well with mosquitoes. That went the promotion of manufacturers, hope from buyers. Does not act absolutely. Manufacturers either do not know the laws of physics and the passage of sound through the layers of the soil, or rely on the ignorance of the population.

Maxim, St. Petersburg

With greater efficiency, the impact on the bear can be low frequencies. Insects feel uncomfortable, leave holes. There are no such devices yet.
