As gardeners, I have three years Internet forums trying with various tips and advice from friends or from me to resist the voles. Either it did not help, or it was short-lived. By chance, I came across an Internet report (with movies), who recommended this Supercat trap. So the double ordered, within a few days came the package and without much effort was a narrow metal rod of the mice explored passage, a hole with a flower bulb Stecher gouged, the case used / provided inside and slightly tensioned with the overhead handle. It took less than two days since the handle / the voltage was lowered! A sure sign that a vole in the case was. This then repeated in a few days even four times. Easy to use, robust and clean. I can honestly recommend.
