Can bed bugs go through walls?

Bedbugs are not like fleas; bedbugs do not jump. They crawl and like dark places where people sit or lie for long periods of time... on beds or couches, or on sheets and pillows. So unless the room is completely overtaken by a huge population of bedbugs, you shouldn't carry them out with you unless your pant legs get near upholstered furniture or bed. Many people get them in infested hotel rooms because they put clothes on the bed, then into the suitcase, and take them home with them.
