TATUNER Ultrasonic Pest Repeller, Mouse Repellent plug in

After the ground opposite my house had been cleared, including a very old shed, to my horror, I went in my kitchen one early evening to find a rat staring at me. It has got in through my adjoining outhouse next to the kitchen, by digging it’s way through my 200+ years old walls. I tried sticky pads, poison bait & everything else I could think of. Certainly these things annoyed them as found tiny chewed up sticky pads all over the carpet,& they stayed away a day or two, but always came back. I’d spent a fortune without success. I then heard about these ultrasonic ones with a good write up & purchased 2 to cover kitchen & living room. I put them on the most powerful setting where I can hear them, but not too much. From that day on they’ve stayed on perminently & I have not been bothered by any rats or anything else ever since. My saviour. Thanks so very much.
