Some other protective measures, like the ones taken at the College of Charleston, make it harder for the bugs to get a foothold.

Randy Beaver, the College of Charleston’s director of environmental health and safety, says his office investigates a room whenever a student thinks he has bedbugs. In the three years he’s been in that position, there have been no confirmed cases of Bedbug infestation. The college, he says, follows both Centers for Disease Control and Harvard School of Public Health guidelines for dealing with bedbugs.
