Ultrasonic pest repellents are designed to repel pests by emitting a high frequency noise that is so unpleasant to them that they stay away from the area. They are usually small devices that plug into a wall outlet, this makes them simple and easy to use. Another advantage to using them is that they are not harmful to humans or larger pets. However, let’s get back to the question, do they work?
Studies performed to test the effectiveness of such a device have yielded a variety of results. For instance, they have been shown to have very little effect on pests such as cockroaches and do not seem to have any effect on spiders and ants. It is also possible for some pests to even get used to the noise meaning that they could eventually stop becoming a deterrent at all. Another issue is that the high frequency sound will not pass through furniture or walls, this means that the area covered might not be that great.
On the other hand, there are many consumers who have experienced great results from ultrasonic pest repellents. So, what should you do?
The best thing to do if you decide you would like to try them out is do some research to decide which brand has the best reviews. In this way you will make an informed decision. If you find that this is not an effective pest control method, it might be wise to call a professional for advice on what you should do.
