Bed bugs are pests of domestic animals, bats, wild birds, and man.
Climex lectularius is the only species in the north temperate regions that attacks man. Bed bugs are most commonly found in old hotels and boarding houses, but you can also find them in homes, apartments, restaurants, theaters, buses and offices. They are nocturnal insects, feeding at night and hiding in dark places during the day. Bed bugs feed only on blood, principally that of man. The period required to obtain a meal is anywhere from 3 to 15 minutes.
