Early last Sunday morning I turn on the television and all I seem to see are infomercials, infomercials, infomercials.
One in particular caught my attention was one for a product called “Pest OFFense”. From the advertisement it states it uses some form of “force field” to keep out rodents, cockroaches, spiders, and similar pests. The ad claims it is not ultrasonics, but rather uses the wiring system in the home to create vibrations that encourage the pest to leave.
I checked the website:

and no scientific evidence there.
Could such a device work, or is it basically a scam?
