We have all had a problem with household pests at some point; mice, rats, spiders, roaches, mosquitos, ants or whatever it may have been. I was skeptical of this product at first. It seemed too easy, but I am not skeptical anymore, it seems to work. Rid Tech Ultrasonic Pest Repeller is a small box that you plug into a wall outlet, and it uses state of the art technology to drive pests away.It uses low frequency sound waves that are inaudible to humans and pets, but drive pests out of your home for good. The part I love about this the most is that it's humane. Nobody wants these pests in their home, but I don't want to hurt or kill any creature, so while this device drives them away, it doesn't hurt or kill them . It's safe and effective. It just creates an uncomfortable environment for them, so they leave on their own. One unit will take care of one advantage sized room, larger area may require more than one unit. This product is the answer to your pest problems. I have had no issues with any of the critters that we had previous to the use of this product. If you want to try it, you can find it on Amazon here.
