Ultrasonic pest reject reviews: Unfortunately, the background of ultrasound repellents is extremely shaky. But it appears to be an appealing idea, doesn’t it? Simply plug a charger-sized device that emits undetectable noise into the wall, wait about 2 weeks, and BAM, your garage oasis is free of rodents and insects without the use of chemical pesticides or inhumane traps. That’s fantastic! That’s fantastic! Too many things have never been proven to work with these devices.
Ultrasonic sound waves have more frequency than human ears can hear, but they can be detected by invading species. The sound will irritate angry criteria and prevent them from building homes in the vicinity of the noise source. I’m pretty sure it’s like I feel for the constant construction of Montreal – I’d move away if I had the choice, in all fairness. But that’s only theory meaningful. In fact, some animals appear to be accustomed to the noise, while others don’t seem bothered.
Some studies in perfect laboratory conditions show that ultrasound can be fatal to some species by increasing their body temperature critically or causing sound-induced seizures. Therefore, the human idea that pests with massive headaches will simply sneak out of your garage is equally wrong. However, these findings have not been replicated in actual homes due to the varying nature of pest invasions.
