Today there are many types of scarers with different operating principles. This article will describe the most effective scarers of wild animals.

Large animal repeller: what is it, principle of operation

A repeller is a device that drives away large, small animals, rodents or birds by turning on high-frequency vibrations that irritate the nervous system of animals.

Animal scarer

Effects achieved when using sensors:

  • animals and birds cannot sleep, drink or eat near the device, as they begin to experience strong pressure on the nervous system;
  • the impact has such a strong effect that the animals experience physical pain;
  • as a consequence of the two facts listed above, animals change their location.

There are 3 most powerful and demanded types of repellents:

  • ultrasonic;
  • electronic;
  • spray.

Ultrasonic Animal Repeller

The essence of its work lies in the fact that a person is able to pick up sound signals with a frequency of up to 20 thousand Hz. All indicators that are above this mark are called ultrasonic. And a person does not hear these ultrasonic waves, but animals are able to recognize such sounds. Hearing them, the animals experience discomfort and try to move away from the source of the unpleasant signal as far as possible.

Electronic repeller

This device can have several modes of operation. The frequency of ultrasignals is manually set.

Important! Some deterrent devices have a light shield option. In the daytime it is unavailable, but at night the device automatically turns on the light, the bright glow of the LED lamp doubles the effect and scares away animals many times better.

Spray

In most cases, this method of protecting the territory is used against bears and cats. Cow and horse repeller spray is also very popular. The tool is often used in cases of danger in order to protect against an attacking beast.

Features of the impact of ultrasonic devices

Tornado Ultrasonic Mouse Repeller

A good ultrasonic repeller generates and emits signals through the speakers every 5-7 seconds. Sounds are characterized by a tonality from 13,000 to 60,000 Hz. While the repelling signal is being transmitted, a flashing green LED starts to work in parallel. Most devices of this type are only used outdoors. They should not be used near such pets and small rodents as:

  • rats;
  • mice;
  • hamsters;
  • Guinea pigs;
  • gerbils;
  • rabbits;
  • proteins;
  • ferrets.

These protective devices are distinguished by a humane effect, since they do not bring any harm to wild animals. All wild animals affected by the device remain alive. The main thing is that the animals are trying to quickly leave the territory through which ultrasonic waves propagate.

The best kind of device in the fight against animals such as wild boars and cows

Ultrasonic Fly Repeller

Which repeller should you choose to scare away large animals? Ultrasonic installations are excellent helpers that can repel pests.

The device is fixed next to the area, which must be protected from pests. As soon as the animal enters the area, an installed infrared sensor recognizes it. The broadcast of ultrasonic waves starts automatically. The "shock" sound wave of ultrasound is instantly heard to the auditory sensory system of animals. This unpleasant wave delivers such discomfort that the animal tries to escape from the territory as quickly as possible.

With their high efficiency, such structures are distinguished by a humane method of work and do not cause any serious or even moderate harm. You should be careful when installing the device in the presence of small rodents such as squirrels or guinea pigs: such protective schemes can harm small animals.

Why choose an ultrasonic repellent device?

The advantages of ultrasound devices:

  • do not require constant updating, as is the case with baits and poisons;
  • do not bring discomfort to people;
  • do not harm large animals;
  • wide range of variable frequencies;
  • autonomy (run on batteries, solar panels);
  • have a built-in battery for continuous operation even in case of emergency power off;
  • do not create a distracting background with interference;
  • in order to cover the largest radius of influence, the devices are equipped with pulse generators.

Important! The ability to change frequencies eliminates the likelihood that animals will adapt to sound effects.

When the owner of the clever device sets it up for normal mode, the sensor starts working. Such a sensor or motion sensor detects movements in the radius in which the device is capable of operating. A good ultrasonic repeller generates and emits signals through the speakers every 5-7 seconds.

Portable Ultrasonic Repeller

The device becomes most convenient when it has a transfer function and is not stationary. Today, there are a huge number of variations on the market for deterrent designs with batteries, accumulators or solar panels. Devices can not only be transferred from one area of ​​the site to another, but also can be safely taken with you to nature. The territory will be sheltered from pests, and in the case of a trip to nature, safety for the whole family will be ensured.

The working radius of portable structures is up to 2.5 meters. Ultrasonic "protectors" do not affect the operation of any other electronic devices.

Modern repeller

The harm of scarers to animals or humans

One of the most important advantages of ultrasonic sensors is that they are absolutely harmless to both humans and large animals (cow and horse scarers are also safe). The ultrasonic repeller does not touch people in any way, the sound can only scare away animals, but in no way harm them. A boar or fox repeller can be dangerous for small rodents, so you should be vigilant if there are domestic rodents in the range of the device.

A huge range of various deterrent devices is due to high demand. There is even a shark repeller. Modern designs are as efficient as possible and absolutely harmless.
