Bedbugs have recently been found on the campus of Wake Forest University. Officials say dogs discovered evidence of the pests in a very small number of dorm rooms. Those rooms have been treated and are expected to be free of bedbugs as students arrive. Michael Waldvogel is an associate professor of entomology at North Carolina Statue University. He says N.C. State and Wake Forest use heat generating equipment to deal with any outbreaks of bedbugs.
