I've noticed two mysterious black lines, about 3 feet long and 3 inches wide, appearing on my beige carpet in the living room. My house is quite old and sits on a raised foundation. Has anyone else experienced something similar or have ideas about what might be happening?

Got any pictures? That might help us figure this out better.
It might be that you have hardwood floors underneath your carpet. If there are gaps in the boards, moisture could be seeping through, which could lead to mold or mildew forming. Definitely worth checking that out!
Oh dear, that doesn't sound good! Thanks for the info.
