I'm not an expert, but I did encounter bedbugs repeatedly in Asia in the 80s and never took the bugs with me. As long as a person does not leave their luggage or clothing on the bed, carpeted floor, overstuffed chair, or luggage rack, the chance of taking bugs home is nearly nil.

If you are bitten (look for bites in straight lines, or sometimes circles) bag up any sleepwear into that handy plastic laundry bag hanging in the closet and either discard or wash and dry on high heat immediately on return home.
