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.
"It's no secret that bedbugs are making a comeback," said Dan Suiter, an associate professor of entomology at the University of Georgia.
Before World War II, bedbug infestations were common in the U.S., but they were virtually eradicated through improvements in hygiene and the widespread use of DDT in the 1940s and 1950s.
Bedbugs are tiny brownish, flattened insects that feed exclusively on the blood of animals and humans. Their bites may cause itchy red welts or swelling.
