I have Voles getting into my hanging plants, eating on the roots of the plants thus killing them. I live in Western Kentucky, USA. as i understand it, unlike moles, who eat insects, they go for vegetation. I have no pictures, have already thrown plants away. I know they are the Voles because of the size of their entry hole one the side of the plant.
Voles can be quite destructive. This article has some information for you on control of these pests.
