Animal in house
I have some sort of animal in the walls of my house. Sitting on the couch about 12 feet away from the wall, I can hear a chewing/scratching noise. Besides tearing my walls apart, how do I find out what it is? How do I find out how it got here? How do I get rid of it? I checked the attic, and I see no signs of an animal. No feces, nothing is torn up, no foot prints, etc. PLease help!
