Will a high pitch sound deterrent machine work to get rid of pigeons?
If you are dealing with a pigeon problem, then most likely, you are willing to try anything on the market. While the advertised high frequency and high pitch sound producing machines are advertised to deter pigeons; they actually don’t! The concept behind these machines is that the human hearing cannot pick up the sounds produced by them, but it is thought that certain species of bird can pick up the sound and will be deterred by it. In order for this hypothesis to be true, you would need to create the perfect conditions for deterring pigeons.
The units are usually very expensive and need to be setup outdoors in order for them to “function” properly. They run on household power, but there are units that can be purchased that run purely on solar power. If you are setting up this unit outdoors, it needs to be covered and placed in a certain area so that it will have the greatest effect. The truth of the matter is, there is no effect. The sound these boxes produce needs perfect conditions in order for it to work. This means that it cannot have any other interference at that frequency level.
These machines can also be very dangerous to humans and can even disrupt the local wildlife; all while not getting rid of your pigeon problem. Younger people tend to have better hearing so they are more likely to pick up the sounds that these machines produce. This in particular can cause headaches and discomfort. In addition to posing a potential health threat to humans, it can also deter and be uncomfortable for other wildlife. In some case and in some areas of the world, it is illegal to use these high frequency sound producing machines since they interfere with the locally protected fauna.
As you can gather from the above mentioned text, these high frequency noise makers, can literally cause a headache, but will fail at getting rid of your pigeon problem. They can even be dangerous to your health and health and wellbeing of other animals. If you are considering this as a means to deter pigeons; there are much better, safer and cheaper ways to do it. This particular method has not shown any long lasting results due to the fact that there are a lot of pieces to the equation in order for this to work.
