I've been using glue boards inside buildings for years and had hardly ever caught any mice or voles on them. A few years ago, I switched to using "JT Eaton Stick-Em 157 Mighty Glue Board for Rats and Mice, Black" (available on Amazon). I replaced one of my glue boards with one of these to get a catch rate comparison. I caught thirteen mice and voles on it in the first week. I've been using these ever since.
