I have a scratching in my wall near my window at night, it is extremely annoying. What could it be?
At about 4am I was woke up by a faint scratching in my wall. It got louder once I noticed where is was coming from. I don't think it is a mouse because I banged on the wall and nothing scurried away. When I turn on a light it stops, and the strangest thing is that it only stopped completely when I opened my window. Am I just goIng insane or could there be something inside?
