Which of these common insect pests is a bed bug (Cimex lectularius)? In a survey conducted by researchers at the University of Kentucky, just 35 percent of U.S. business travelers and 28 percent of leisure travelers could correctly identify the bed bug. Poor awareness of bed bugs enables their spread and causes problems for the hotel and lodging industry. The answers: 1-Ant, 2-Termite, 3-Louse, 4-Bed Bug, 5-Tick.
