There's something scratching and around in the rafters above our upstairs bedrooms. It's very active between 3-5 AM, which leads me to believe it's a rat, rather than a squirrel. With great effort I hauled my bulk into the attic. Sure enough, there are some turds up there, but the nocturnal action is coming from the end of the house that's not accessible to a person (the house is a split-level, about 50 years old.)
I think I'm going to have to resort to getting a professional. You guys have any bright ideas? This is driving us nuts.
