In this undated photo released July 24, 2001, by the University of Florida, a common bedbug is engorged with blood after feeding on a human arm. Absent from the U.S. for so long that some thought they were a myth, bedbugs are back. Entomologists and pest control professionals are reporting a dramatic increase in infestations throughout the country, and no one knows exactly why. (AP Photo/University of Florida, File)
