For anyone who has accumulated an annoying swarm of birds, whether it’s at your home or business, Don’t Panic! There is an effective solution. What some of the most ingenious people have been able to do is take a common product and transform it into an effective bird repellent. In this article I will show you how to build a simple bird repellent system out of items that you may already have around the house Have you ever been bothered by these unwanted birds on your balcony, garden or all over your house? You don’t want to harm these poor creatures but you also have to get rid of them. There are a lot of ways to scare them off, but most of them fail to deliver in the real world scenario. This is where sound-based Bird Repellent comes into play.
Birds Repellent Ultrasonic
How Do Bird Ultrasonic Repellers Work?
The idea or concept behind ultrasonic repellers is actually quite simple. They emit a high-frequency tone or noise, usually in 15-20 kHz range and above.
This is outside the normal audible range for human beings but well within the audible hearing range for many animals and insects. You may have heard how dogs will howl when a dog whistle is blown (also outside of human hearing) because it hurts their ears.
The same thing holds true with ultrasonic repellers.
Moreover, many repellers will use alternating sounds, going back and forth much like a European police siren. If you’ve ever heard one of them, you know they’re incredibly annoying. If you haven’t, click on the link above and you’ll see what we mean.
After only a few moments you want to clap your hands over your ears and hit “stop” to put an end to the caterwauling of those things.
But imagine not being able to stop it. Imagine it getting worse as you get closer and closer to your destination. Basically, that’s what is supposed to happen to birds as they approach the ultrasonic repeller, the sound is intended to be so annoying they tuck tail and run – or fly, as the case may be.

Many ultrasonic repellers also add flashing LED strobe lights and sonic (i.e., humanly audible) sounds as well. The combination, alternating back and forth, should prove to be more than it’s worth to the birds and they’ll seek shelter somewhere else.
Another thing to note is the motion detection sensors most repellers have had added to them of late. This is actually an excellent idea.
The bird approaches thinking everything is fine. It crosses the line where the sensors can detect their presence and suddenly, all you-know-what breaks loose. Birds are very skittish anyway and the unexpected nature of the explosive noise and light adds to their fright, alarming them into flying away.
Do Ultrasonic Repellers Really Work?
This is a little harder to answer. There are two kinds of evidence to consider in trying to answer this question; scientific research evidence and anecdotal evidence.
Scientific research evidence is the evidence which has been collected in rigorous, carefully planned studies which should take place under controlled conditions, or at least in conditions where all the possible variables have been accounted for and taken into consideration.
The research to acquire this sort of evidence requires a great deal of time and money to conduct. In other words, it’s time-consuming and expensive.
Consequently, very little research of this type has actually been done. There are some articles on university websites that talk about repellers, usually denigrating them, but we’ve noticed they rarely quote any actual studies.
They claim studies have been done but when you dig into it, there aren’t any rigorous studies. What little research has been done is almost anecdotal itself.
Anecdotal evidence is the evidence from first-hand, eyewitness testimony of people who have used the devices at their home or business and can tell you what happened to them.
When considering the weight of anecdotal evidence, remember this is the same sort of evidence that is admissible in a court of law to find someone guilty or not guilty of a crime beyond a reasonable doubt.
In civil trials, the verdict often hinges on what is called the “preponderance of evidence” standard, and it can be enough to justify handing out fines of tens of millions of dollars in some cases. So anecdotal evidence is actually very good, solid evidence that can certainly be considered.
The anecdotal evidence seems to be about 60%-40% in favor of ultrasonic repellers working. A lot of their success hinges on the placement of them and how many are being used.
How Should Ultrasonic Repellers Be Used To Remove Birds?
As mentioned earlier, the most annoying sounds are the undulating, back-and-forth types of noises like European police sirens. Those sirens were specifically designed to be annoying and attention-grabbing, by the way.
That’s what you want to be done with ultrasonic repellers.
For this reason, we recommend getting a minimum of two repellers at a time. Three or four would be ideal, but two is the bare minimum you should get.
Set them up so their range overlaps by about 2/3’s but far enough apart that they won’t be triggered at the same time. Then, when the birds fly into the “trigger zone” they’ll be hit with different noises and flashes of light from two different directions, all of which are out of sync with each other – creating that undulating, alternating noise that will drive the birds crazy.
Place the repellers against a solid wall or large tree trunk. This will bounce the sound waves back into the open area in front of the device. Whatever you do, don’t put them down on the ground even if the directions state that you can.

The closer they are to the ground the more “clutter” there will be break up the frequencies. You’re trying to frighten away birds that are flying in the air so putting the repellers on the ground seems counter-productive anyway.
Many of the repellers allow you to set different frequencies when you turn them on. If possible, turn each repeller to a different frequency to increase the “police siren” effect. You might even consider getting several repellers, one from each of several different manufacturers.
Experiment with different settings, placements, and patterns. Just because you’re not getting results one way, doesn’t mean you won’t get good results by using them in a new configuration.
Play with it a little bit. Do your own research. You might find yourself pleasantly surprised at the outcome.
