How do you get rid of mice in attic when there is no attic opening?

Answer:
They got up there through a wall. Find the small hole they are using to go up and down for food/water and place a tin cat or traps in that area. Look where plumbing passes through under sinks etc. Check the structure for any holes, door gaps, screens over vents, etc.
