I know this sounds like woo woo, but try an illuminated Himalayan salt block. The heat creates ions or some such and it has helped a great deal in my son's bedroom where the cats ruined the carpet when he was away for an extended period.
Somebody also recommended dumping unscented kitty litter on the spots, letting it sit for a week, and then vacuuming the stuff up, but caveat emptor as we have not tried that yet. In my mind, if that crap got damp, it would probably ruin the carpet.
