I recently started smelling a foul odor in my vacant bedroom upstairs. This is the only room that I smell this odor in. It is like a spicy smell. It is hard for me to describe. I bagged everything up in the room. I went into the attic off of my sons room and I smelt nothing. I must mention that I stay in an attached home. I don't know if its my neighbor or not. I need to know where this smell is coming from. I have a kid on the way that will at one point occupy this room and he cannot be in that room with that odor lingering. I need help. I can only assume that it is a dead animal but I am not sure. I do not smell this odor nowhere else in the house. I keep the door closed. I don't even smell it my sons room next door. I just started to smell this odor two days ago and I really need help. I have a kid on the way and I can't deal with this when he gets here please help.
