By being carried — travel and the movement of infested items between locations is one of the reasons cited for the modern resurgence in bed bugs, alongside insecticide resistance. They don't need to travel far on their own to spread widely; a single infested bag moving between a hotel room and a home does the work.

What should I check when I get home from a trip?
Inspect luggage before bringing it into a bedroom — check seams, pockets, and folds for the same signs that confirm an infestation anywhere else: live insects, fecal spots, blood spots, egg cases, or shed skins. If anything looks uncertain, treat the bag the way you'd treat clothing during preparation for treatment: bag it, and launder anything washable on the hottest setting the fabric allows for at least 30 minutes.
What about a car?
The sourced guidance doesn't give car-specific temperature or timing figures, but the same detection principle applies: bed bugs hide in crevices as small as the width of a credit card, so seat seams and floor-mat edges are worth checking if you've had a suspected exposure. Treat a car the same cautious way you'd treat luggage — inspect, and don't move uncertain items straight into your home.

Is hotel travel really a major source?
It's one of the sourced contributing factors, alongside general resurgence trends. UC IPM's extension research notes bed bugs "can now be found even in the finest hotel and living accommodations," driven partly by increased global travel and commerce and the ease with which infested items move between locations. See our hotel room inspection page for what to check on arrival.
