There are many types of devices that can be used to get rid of pesky birds in and around your property. Everyone who has tried these repellents have their opinions about how effective they are. When it comes to using ultrasonic bird control there seems to be two polarized opinions about it. It seems that there has been a long-standing debate about their effectiveness in different situations.
How Do They Work?
Most ultrasonic devices rely on electricity to operate. They are often the most popular when it comes to pest control. They produce an ultrasonic frequency that registers about 20 KHz, a level that cannot be heard by humans but is believed to cause extreme discomfort in animals. The result is often fear, disorientation, and in some cases physical pain to the birds that fly into the area.
However, there are some that believe that these devices only work for a short while. As the birds acclimate to the ultrasonic sound waves, they will no longer avoid the place and will return en masse to repopulate it again. To eliminate this problem, many of the newer ultrasonic bird control devices are designed to emit varying frequencies so that the birds are unable to adjust to the new signals.
A Humane Approach:
One of the reasons these devices are so popular is because they do not cause any lasting harm to the birds. The use of ultrasonic waves is considered to be one of the friendliest alternatives to simply killing them or shooting them down with pellet guns. It also prevents the property owner from needing to dispose of dead carcasses in a safe and hygienic way.
Convenient:
Because ultrasonic bird control devices use high frequencies that are above the normal range of human hearing they are most effective indoors. Manufacturers recommend that you have several devices that you periodically move from one area to the next to get the most coverage possible. Finding those devices that can change their frequencies periodically will also give the best protection from pests entering your property. This will help to avoid reinfestation once the area is cleared of all the nuisance birds on your property.
Of course, ultrasonic devices are not the only way to get rid of a nuisance bird population in your surroundings. There are other sensory devices that may be just as effective. Electromagnetic devices, for example, generate their own magnetic field that can also deter birds and other pests from coming around. The electromagnetic field interferes with the natural instinct to feed and reproduce so they will eventually force the pests away from the property. They are easy to install and can quickly be adjusted to the type of birds you want to get rid of.
It goes without saying that there is no single device that will effectively remove birds from your property permanently. Regardless of the device you choose to use, it will need to be an ongoing job that will require diligent effort to succeed. However, if you do you'll find that you can have a completely bird free environment that everyone can enjoy.
