Ultrasonic pigeon repeller, its effectiveness, other types of repellers

It is difficult to overestimate the benefits that birds, in particular pigeons, bring. They destroy a huge number of harmful substances for the garden and vegetable garden. insects, especially during the period of feeding chicks.

But at the same time, birds can cause a lot of trouble for gardeners and vegetable growers, since their favorite delicacies are seedlings of cultivated plants and ripe fruits.

The close proximity to birds has long forced landowners to resort to various tricks: they used stuffed animals, sound signals, attracted dogs to help, and adopted fairly modern effective devices, such as an ultrasonic pigeon repeller.

Ways to scare away birds

First of all, you should understand the reasons for the increased interest of birds in your area. It is quite possible that your family members or neighbors feed them. If the cause of constant pigeon raids is not the provoking behavior of people, then you will need to take serious care in purchasing repellents and installing them on the site.

Such devices, depending on the principle of their operation, can be divided into several types:

• visual bird repeller
• ultrasonic, the principle of which is to produce high-frequency sounds
• bioacoustic
• sound

You can often find a homemade pigeon repeller.

Of course, all these devices have different types, dimensions and costs.

Visual repellers and their effectiveness

The cheapest and most accessible for self-production. They are stuffed or imitate the appearance of feathered predators or animals that can hunt pigeons.

The combination of threatening outlines of predators and bright geometric shapes evokes a feeling of danger in birds. Making such a device yourself is not at all difficult and not expensive. because You can use improvised means for work. But this option is not used often, since the desired effect is unlikely to be obtained.

Using a combination of visual and bioacoustic repellers will be much more effective, especially if the area is large and open.

Seeing a potentially dangerous creature, whose presence is confirmed by sound, the bird panics; the instinct of self-preservation forces it to leave the territory where there is a threat to life. Subsequently, frightened birds prefer to avoid returning to this area.

Both bioacoustic and visual repellers are not very effective, so in most cases they are used in combination.

Sonic and ultrasonic repellers

An ultrasonic pigeon repeller is essentially a generator of high-frequency impulses, inaudible to humans, which cause a feeling of terrible discomfort in birds.To enhance the effect, the device is equipped with a light flash generator.

An undeniably important positive aspect for humans is the silent operation of the device.

The price of the device is relatively high, above $50.

A significant drawback is the small area of ​​​​action, it can be a balcony, terrace, or roof area.

Among the positive aspects, we should remember the fact that after three weeks of using the device, birds develop a stable dislike for this area, they prefer to stay away from it.

For example, the ultrasonic bird repeller ls-987bf, equipped with a special sensor, is triggered when birds approach at a distance of 12 m, and operates in an angle range of 70 degrees. It emits a changing ultrasonic signal and a light signal from a working LED. There are special connectors for mounting the device on the wall.

Sound repellers

Sound repellers are units equipped with gas guns. The automatic device is programmed in such a way that, at certain intervals, flammable gas is supplied to special chambers; when it is ignited, a loud sound is made that scares away birds.

The tripod on which the device is attached ensures its rotation around its own axis, which significantly increases the area over which sound waves propagate.

This type of repeller is quite effective; it provides protection against birds over an area of ​​5 to 10 hectares.

Typically used to protect fields with sunflower, orchards, plantations grapes, territories of industrial enterprises and airports.

Is it possible to make a pigeon repeller with your own hands?

There are many options for making homemade repellers, some of them have an extremely simple design. For example, in just a few minutes you can build a device from film that was used for video and audio cassettes.

The film is cut into small pieces, fastened on one side, tied to a cord and hung in places that are subject to bird infestation. Fragments of the film begin to move at the slightest movement of air, make noise and flicker, which scares away birds.

It’s just as easy to make a device from old CDs. Several pieces are attached to a string and hung in a place that requires protection. The discs sparkle in the sun and make a slight noise, scaring the pigeons.

Homemade ultrasonic pigeon repeller

Build an ultrasonic repeller birds It’s also possible to do it yourself, but for this you will need:

• device diagram
• set of resistors, transistors, diodes and capacitors
• new or used piezo emitter, this is a required component
• an old board or piece of fiberglass that will serve as the basis for assembling the device
• soldering iron

Naturally, it will be quite difficult for a person who does not have assembly skills to build a device.

Self-made repellers are quite cheap to manufacture, but their effectiveness is not high, their effect can be limited by weather conditions, and their range is small. They can be used to protect against birds balcony or terrace.

Not everyone can make complex homemade electronic devices. Therefore, the best option for protecting a large garden or field can be considered a purchased device that operates efficiently and reliably.
