Bests & Worsts Reviews from Amazon

I have been putting these pellets out every day for the last 20 days. I put them on a paper plate a few yards away from my bed where I can watch the mice come and help themselves to these tasty treats. They must enjoy them very much cause they come back every night for more. Same thing for all the other rooms where I have placed them. The pellets keep disappearing but the mice remain. Either this stuff is totally ineffectual or I have a strain of super mice in my house. I really can't recommend this. Probably best to get some cats.
