Cure for the mouse problem

Maybe if it is spiked with something that tastes horrible to them. Otherwise, no way.

Rats are even worse, they tunneled into our attic from the roof by chewing through the stucco under the eves. They also worked their way down the inside of a wall from there and tore out the stucco around the garage sink drain. The roof problem was resolved by nailing metal flashing into that location - rats can chew through a lot, but not steel sheet. I did use some foam to fill up the hole around the drain after placing several layers of strong metal mesh there too. The foam expanded on both sides of the mesh. Followed that with a very unpleasant week of servicing rat traps containing severely injured but not dead rats. (The rat traps killed the two adults as advertised, but only maimed the juveniles. It was really disgusting.) No more rat problems since. Not that I don't expect them to find another way in at some point.
