How Can I Stop My Papillon From Chewing On Everything?

he tears the wood stuff out of our fake trees chews on our clothes and everthing else he can get ahold of. we walk him for 2-3 hours a day and train him for about an hour. should we try taste deterents? does any one have any advice? please help. he also still goes to the bathroom in his box even though he is only in there for at most 3 hours at a time.
