As anyone who has ever had them in their household can attest pests are very aptly named. They have been with us throughout history and unfortunately are still with us today. Despite numerous attempts and innovations when it comes to pest repellants nothing seems to prove the definitive efficiency.
There might not be a definitive solution for pest control but some do come close enough
In the last decade, one of the more popular in non-intrusive products has been the great ultrasonic pest repeller, basically a new innovation that is based on a very, very old idea. In ancient china, they used to have devices which were based around emitting sound that were used to protect not only households but even agricultural fields from pests. These devices however, unlike nowadays were mechanically operated. Today we just plug them into a power socket and they emit a continuous stream of high pitched sounds that are highly effective and disruptive to pests. The best part about ultrasonic emitters is that the human ear is incapable of receiving noises in that range so we are completely unaffected by the device and it is left free to wreak havoc among the rats and cockroaches that infest our living spaces. The pests are entering something called audio genic seizure response when exposed to the ultrasonic sound and experience chaotic movement patterns, convulsions and in some circumstances they can even die from cerebral hemorrhage.
An ultrasonic pest repeller will not however affect your household pets such as cats and dogs. Even though both species are known to be able to hear in the ultrasonic range extensive studies have shown that the noise does not bother and it barely registers with them, see more insect repellers here. A very important thing to remember when buying such a device is that we need to be very careful where we plug it in if we want to maximize its efficiency. They need to be placed in open areas where their signal emitted will not be obstructed by furniture and by walls. It is advisable to buy several devices in order to properly insulate the household but even so placing them in key areas that boost their efficiency will go a long way toward ridding you of the pests fast and also ensuring they do not return to bother you again. There are many options nowadays when it comes to pest control but most of them are not only very inconvenient since some even require us to leave home for a few days but they are also at best temporary. An ultrasonic repeller solution works for as long as your house has electricity and provides extreme ease of use.
