I trap mice around the outside of the house in the autumn trying to keep the ones that manage to get inside down to a minimum. I bait the traps with peanut butter. I have noticed that I catch many field mice but very few voles (nine field mice to one vole approximately). I don't know whether that means voles do not like peanut butter as much as field mice do or whether there are many field mice and few voles around the house.
