With regards to how they work, ultrasonic pest control devices are made to plug into any electrical outlet and, when turned on, emit an ultra-high frequency sound that is unpleasant to small creatures. This will then force them to avoid areas where they hear the sound. These devices are also safe to use around larger animals and humans as the sound does not affect them.
But now the question of do they work? Studies have been conducted to see how effective ultrasonic pest control is. Results have shown that some creatures become used to the sound, so it didn’t deter them for good. Other studies showed that this was not effective on every type of pest. Ants and spiders did not seem to be affected by them and cockroaches didn’t seem bothered by them either. The high-frequency sound is not able to travel through objects either so, in rooms full of furniture, the pest control coverage area will be greatly reduced.
While these results appear to be rather negative many consumers have found the ultrasonic plug-in devices to be a very effective form of pest control. So, what should we conclude? If you decide you would like to try them yourself, do a little research on the different brands available and read customer reviews on each type. This way you will choose the best one. Its also important to remember that if the pest problem is a severe one, it would be best to consult with a pest control company that can advise you on the best way to tackle the problem.
