I had that problem some years ago in some rooms from which I had removed most of the furniture during painting. I got an installer to restretch the rug; he was not the one who had originally installed the rug. The original installer used what might be called a knee-kicker; the second used a stretcher that had braces that went from wall to wall. The latter system was much more effective. The problem hasn't come back in those rooms.
