A friend recommended baited (poisoned) traps as a straightforward way to get rid of the mouse (mice?) in my garage.
My dad says old fashioned spring traps are preferable because no matter how careful you are with the poisoned ones, they have to be disposed of and you don't know what might be affected by them afterwards I.e. what else might be affected by the poison.
I don't love the idea of squashed mice, but they do need to go and none of the solutions are particularly palatable
