We live in a berm home in the country, with the roof being a couple feet off the ground. Our problem is that we hear what seems to be something moving around in the attic, we have tried poison, live traps, glue traps, rat traps,etc. We caulked and applied screening material to all vents, leaving no holes. Now we are getting a very strong musty oder in our living area, Don't know what to do?
