You may have seen the TV commercials proclaiming that there is a plug-in electronic device that is effective at ridding your home of roaches. It does sound enticing, doesn’t it? No sticky gels or powders to disperse, no traps to lay, just plug in the wall and the roaches are gone. But does it really work?
Two types of electric repellents
These devices work in either one of two ways. The first type and most prevalent on the market works with radio waves. They send an ultrasonic radio waves throughout the home that humans cannot hear, but roaches, rodents, and other critters can. Supposedly, the radio waves sufficiently irritate the roaches to where they clear away from the area.
The other type claims to adjust the electromagnetic frequencies in your home using the electrical wires that are laid throughout the house, mainly in the walls. It creates an electromagnetic disturbance that people can not notice, but it drives away the roaches.
Do they really work?
Despite the lofty claims of the manufacturers of these devices, the results are spotty at best. In fact, several manufacturers have been sued by the Federal Trade Commission for using unproven claims in their advertising.
The verdict from consumers has been a mixed bag. Some people claim that the devices work for them, but the majority of people say that they either do not work at all, or have very little effect at repelling roaches from their home.
I recommend you stick to traditional roach killers
My opinion is that these “electronic roach repellents” are more of a gimmick than anything else. There may be some scientific basis for what they attempt to do, and in theory they could work. But in practice they do not really work very well and I would advise you to use other, more proven methods for killing roaches.
You are going to be better off sticking to the tried-and-true products such as boric acid or roach killing paste. These electronic killing machines sure do sound nice in theory, and maybe one day the science will get there.
But as of now, they seem more like a sales gimmick to me and I would stay away. For more information, take a look at my other articles about better ways to handle your roach infestation.
