I bought the 6 pack of the TattyaKoushi pest repellents. After many years of not really having any type of pest problem suddenly my house was invaded with fleas. We tried everything..sprays,bombs,powders you name it we used it. My poor cats were covered with the little nasties. Unfortunately so was my home. We would wake up with bites everywhere. When I saw these, I thought "why not I tried everything else."
At first I was worried about my cats being bothered by these,but everything seems okay. That great. They are really a very nice design and they kinda look like a small night light plugged in. However it's not bright enough to be much help as a nightlight, it's just a glow of alternating colors, red, blue, and green, so you know they are working. You can see the glow in the dark but it's nothing obnoxious, it's just right. It has been a few weeks since purchasing these, and I definitely see an improvement. My cats are scratching less and the bites are gone.I give these little guys a big thumbs up. PS...also have not seen any ants either. yeah!!!
