Bed bugs seem to conjure images of poorly maintained slums or cheap motels. Contrary to what might seem intuitive, the bed-bug epidemic actually started in high-end hotels that catered to international business clientele. It did not take long for them to spread into apartments, college dorms, laundries, cruise ships, movie theaters, hospitals, moving/delivery vans, furniture rental businesses, schools, the work place, and of course all classes of hotels and motels.
There is plenty of cross-contamination involving visitors bringing bed bugs from one location to another (hotel to hotel, hotel to house or apartment, etc..). Moving companies who previously transported a bed with bed-bugs may unknowingly contaminate a subsequently delivered clean bed in the same delivery truck.
