Serves me right for laughing but we’ve got mice in our garage now too.
Mrs Backroads has bought some of those humane mousetraps. They’re good because little Mickey sits there all snug and cosy in his own shit until you gently release him back into the wild, preferably some distance away from the house.
Alternatively, do what I did and, in planning to drive the mouse a long, long way away, rest the trap on top of the car whilst putting a few things in the boot, then slam the boot door, watch the mouse trap wobble and fall off the roof, hit the drive and smash open. Observe concussed mouse noodling deliriously from side to side straight back into the still open garage and back behind the washing machine. Doh!
