The best way to trap mice: My cousin worked in a bakery. You can imagine it was nearly impossible to eliminate all the tiny crumbs and bits of flour and dough that would attract mice. He said they set out the traditional snap traps baited with a dab of peanut butter, but the trick is to place the end with the bait snugly against a wall or vertical surface, because they tend to travel along a wall and will unintentionally end up walking across the end of the trap. Snap! One less mouse.
