So you bought an electronic pest repeller for $9.99 and plug it into an outlet and it repels all insects from your entire house. That’s how it works right? I mean if it were that good there would be no pest control industry! These gimmick devices have been soundly disproven by science again and again. The problem is that people do not believe science and facts so millions of these stupid things are still being sold every year!
Well, here is some visual proof that proves yet again that these things are a gimmick. This ultrasonic unit was plugged into an outlet in an apartment in Boston. As you can see it did absolutely nothing to repel or control the German Cockroaches. In fact they seemed to love the extra warmth it provided as evident by the copious amounts of fecal matter. Perhaps I should go into the snake oil sales business?
