How does a Green Shield pest control unit work? Green Shield is a little box that you plug into a standard electric socket. It’s really simple. Once you’ve plugged it in, it immediately starts broadcasting an electromagnetic field around the house. This field affects only rodents and drives them out. Green Shield’s patented electromagnetic rodent repeller devices oscillate at a specific frequency that affects rodents such as mice and rats whilst leaving humans, other animals and other electronic devices untouched. The field produced by the Green Shield rodent repeller is like a bubble, but it also extends around the electric cables in your walls. The field pulsates, and that’s important. The pulsation interferes with the actual brain chemistry of rodents, affecting their hormones and sleep-wake cycles. This mechanism effectively gives rats and mice a feeling akin to jet lag in humans. The frequency of the electromagnetic waves goes up and down incredibly fast, constantly for three minutes. Then the Green Shield stops, for one minute. Just when ratty or mousy thinks everything’s fine again, ZAP! It starts up again.
