Diatomaceous earth does work, pull beds away from wall and surround them. Go all the way around entire perimeter of every room. Supposedly might have to e.g. kennel dogs as well to avoid feeding them, though I didn't do that.
Not sure how great the stuff is to breath but air here is all glacial silt anyway and it seemed preferable to chemical alternatives.
I cleared the entire apartment building I live in this way.
