Ultrasonic/electronic pest control????
I know there has been much discussion on this subject, but I was wondering about the cheaper units such as the Sunbeam that can be purchased from Wal Mart. Do they work through the wiring in your home also? How big of an area do they cover? I haven't found this info on the package. As for the Riddex on QVC, how long do they last? Is it better to buy several of the smaller units, or a few of the larger ones? If they don't work through the furniture, how can a unit like riddex cover 2000 sq ft? I would very much like to hear from those who have these units about what works best. Your replies will be very much appreciated.
