That is precisely what you are looking at. I had a water leak in the bathroom above this part of the basement (where the tv and vcr normally sit), and once I got the leak stopped, we vacuumed and are running the miners on it. I think the combo of both the air AND the heat has made it even more effective. I didn't even pull the carpet up, as I think this alone will take care of things. The ceiling is another story... :(
