  Just a couple of thoughts on OP.  Unless your dog is mature and has lived around you a long while, to him the carpet is just like grass, a chewie or a twig in the back yard.  And chewing/digging something to do to play and keep busy during the day or night anytime he's bored to tears or frustrated that his pack leader is gone and he's so lonely.  Perhaps you could confine him away from areas and things he can destroy for the time being and train him not to stress or grow frustrated from separation anxiety, keep his life challenging, very well-exercised and be sure he's involved in a good training program of short sessions a few times a day totaling about 15 mins. a day.  You'll be surprised how little, if anything, a very well-trained dog will destroy once his expectations and impulse control are modified by a good life-enrichment, behavior modification program.  Once he's had about 9 mos. to a year of this type program carried out properly, he can be trusted out and about in the house.
