Protecting your garden or garden from winged crop robbers is a headache for all the inhabitants of the countryside. But this is not the only reason why it is necessary to scare away birds in some way. They also pose an immediate danger to human life by flying over airfield runways and are carriers of extremely dangerous diseases and parasitic insects. Dust from bird droppings accumulated in the attic can cause allergies and even lead to death.
But birds are not rats or cockroaches, you need to get rid of them by humane methods, not by killing, but by scaring them away. Designed for this device are called repellers and are divided into ultrasonic, biometric, that is, imitating sounds, and visual, in fact – scarecrows at a higher technological stage of development.

How to choose a bird repeller
There are several main types of bird repellers. To make a choice, you need to decide what budget you have and which device is more suitable specifically for your site.
A visual repeller is the most affordable and easiest option. These include a common garden scarecrow, predator figures, various shiny elements and flashing light bulbs. This type of repeller is suitable for placement in any area.
An ultrasonic repeller is a more expensive and complex device. It makes a sound that is inaccessible to human hearing, but at the same time it is extremely unpleasant for all birds. It causes anxiety among birds and makes them fly as far as possible from your site. Please note that ultrasound will also be unpleasant for poultry. Therefore, if you have parrots, chickens, geese, ducks or other winged pets on your farm, you should choose a different type of repeller.
A biometric repeller is an expensive but effective way to deal with feathered guests on the site. The device emits sounds of predators or cries of panic of a certain species of birds. For example, if starlings are bothering you in the garden, you can turn on the disturbing twitter of their relatives. Birds will think that danger awaits them on your site, and will fly around the territory sideways.
A biometric repeller may not be suitable for installation in a small garden located too close to your house or your neighbors’ houses. Sounds coming from the device may interfere with rest or simply begin to annoy people in the vicinity after a while.
The editors of the KP asked Maxim Sokolov, expert of the online hypermarket “VseInstrumenty.ru” help readers of the KP to decide on the choice of a bird repeller and answer their questions.
What parameters should ultrasonic and biometric bird repellers have?
When buying, you should pay attention to the range of the device. Usually it is written directly on the packaging or on the product card. It is necessary that the operation of the device covers the entire territory where the appearance of birds is undesirable. For example, if you only need to protect an outdoor clothes dryer, you can choose a device with a short range. Multiple appliances can be used to protect a large area.
If you will be installing the repeller in an open area, such as a rooftop or tree without any shelter, make sure it is waterproof. Otherwise, the device may break down during rain or from exposure to morning dew.
Decide on the most suitable way of eating:
- Network devices should be bought if you have the ability to connect to a power outlet on the site.
- Repellers that run on batteries and batteries are more versatile and self-contained, but you will have to periodically change or charge the power source.
- Solar-powered appliances are the most economical – you don’t have to spend money on electricity or new batteries. But they may not perform well on overcast days or when placed in the shade.
If you want to increase the effectiveness of repelling, purchase a device with a combined action. For example, you can choose an ultrasonic or biometric repeller with a built-in flashing light element that will scare the birds even more.
To be able to automate the operation of the device, you can choose a model with different modes. For example, there are repellers that start every 2-5 minutes, turn on when motion is detected in the coverage area, and turn off at night.
It is better to choose biometric devices with volume control – so that you can configure this parameter specifically for your site. If you have a lot of bird species in your garden, you can purchase a repeller with several sounds to scare away different birds.
Popular questions and answers
Are ultrasonic and biometric repellers dangerous for people and animals?
But for pets, the sounds of these devices can be disturbing. For example, a biometric device can scare pets, but over time they get used to it.
Ultrasound can cause anxiety, aggression and unusual behavior in poultry. Unlike wild birds, they cannot simply fly away from your territory without hearing anything.
This can negatively affect their health. Cats, dogs, hamsters and other pets perceive the sound range of a different frequency, so bird repellers will not work on them.
Is it possible to limit the use of a visual repeller?
But if every couple of days you move or re-hang all the items, change the scarecrow into new clothes, then the birds will be scared every time, like for the first time.
Shiny or reflective elements, spinning propellers hung on a tree can be more effective in scaring away winged guests. They are less static than a regular scarecrow, so they keep birds away for longer. But they also need to be periodically outweighed so that feathered pests do not have time to get used to them.
What to do if ultrasonic or biometric repellers do not work?
Also make sure your yard is clear of trash, open compost pits, and other sources of food and water for birds. For the sake of a large amount of food, they will fly into your territory, despite everything that you have done.
For more effective scaring, you can combine different methods of scaring.
– Together with biometric or ultrasonic, use visual repellers, including light ones.
– Install anti-stick spikes on the roof ridge, eaves and other bird-friendly surfaces. So it will be inconvenient for the winged ones to sit down, and they will visit you less often.
From time to time you yourself can make loud noises to scare away birds. For example, you can clap your hands or turn on some music.
If you have a dog or cat, walk them regularly on the yard. Your pets can scare birds better than any special devices.
Install motion-activated sprinklers in the garden. The sound of a sudden operation and water will scare away not only birds, but also moles, mice, frogs and other animals.
