The 3 way Sentinel is our best and most powerful ultrasonic bird & Pigeon repellent/ deterrent that has an adjustable frequency. It has 4 speakers that send ultrasonic sound 150ft in3 different directions. Most of these repellers are solar-powered while others are equipped with long-lasting batteries that need to be recharged once in a while. It’s best to choose one that doesn’t require frequent maintenance to ensure that your property is guarded against pest birds all day long. The lowest setting could eliminate rats, foxes, and weasels. The middle level would be effective for stray cats, badgers, and skunks. For these two settings, I can hear the continuous pitching noise when standing within 1 metre around. High-pitched frequencies deter cats, dogs and other animals from invading your garden. The signal is inaudible to humans but animals find the signal uncomfortable and leave. Other devices emit a constant sound, but Animal Away saves batteries with its infrared motion activation. The PIR sensor detects and triggers ultrasonic/sonic plus flash emission. Switchable to shift to a sonic sound.”
Finding your way to a bird-free life can be difficult. For a low-impact solution that will indeed work, sonic and ultrasonic repellers are an absolute godsend. If you’ve got kids to worry about or easily miffed neighbours, even more so. You might think an ultrasonic bird repellent would be expensive or difficult to install, but Birdsoff offers a range of residential sonic and ultrasonic bird scarers that make ending your bird-based nightmare a simple process. We’ll ship anywhere in Australia, and you’ll be bird-free in no time. Sonic Bird Scarers Are Humane to Use Ultrasonic repellers use high-pitch sounds that will irritate animals, including birds. Unlike sonic or mp3 bird scares, these devices produce ultrasonic soundthat humans can’t hear. This means that you can drive away birds without being a nuisance to your neighbors. These devices could be divided into different groups with other criteria, such as with or without a motion sensor, the infrared region, with or without flashing lights. Why do You Need an Ultrasonic Bird Repeller? (Benefits)Some songbirds may hear up to 20,000 Hz sound. But pigeons can detect the infrasonic sounds, which is from 0.5 Hz to lower than 10 Hz.

It produces the sound of high frequency ranging from 15,000 up to 30,000 Hz, which may annoy or trigger the nervous systems of birds. They also realize the sound as a warning from their predators or an alert of territorial violation so the birds would not come close to the guarded area.
