We were away from our house for a couple of months,
and when we came back there were hundreds of mouse (or rat) droppings
in just 2 rooms.
To get into one of the rooms, the mice had to climb up a 2 metre wall.
They got into the other room through an air-hole.

I'm wondering if there is any way of stopping them climbing a wall?
It's a reasonably smooth plastered wall (outside).

Also, is there anything better than mice traps to dissuade them?
They came through a garden, and I wouldn't like to put anything down
that could harm other animals.

If a mouse is caught in a trap, does it worry the other mice?
Or will they just ignore their dead brother?
