Any member of approximately 75 species of nocturnal insects (family Cimicidae) that feed by sucking the blood of humans and other warm-blooded animals.

The reddish brown adult is broad and flat and less than 0.2 in. (4–5 mm) long. Among the most cosmopolitan of human parasites, they are found in every kind of dwelling. They digest meals slowly; adults have lived for at least a year without food. Though the bite is irritating, it is not known to transmit diseases to humans.

insect
 any of about 75 species of insects in the true bug order, Heteroptera, that feed on the blood of humans and other warm-blooded animals. The reddish brown adult is broad and flat and 4 to 5 mm (less than 0.2 inch) long. The greatly atrophied, scalelike, vestigial wings are inconspicuous and nonfunctioning. The distinctive, oily odour of bedbugs results from a secretion of the scent, or stink, glands. Each female lays an average of 200 or more eggs during a single reproductive period, and three or more generations may be produced in a year.

      Bedbugs are among the most cosmopolitan of human parasites. They are found in every kind of dwelling place, hiding during the day and coming out at night to feed. After feeding, they retreat to their hiding place to digest the meal, which may require several days. Adult specimens have lived for at least a year without food. Although the bedbug has an irritating bite, it is not known to transmit diseases to humans.

      Cimex lectularius, which occurs in temperate regions, and C. hemipterus, which is common in the tropics, attach to humans. The species C. pilosellus lives on bats and, although known as a bat bug, will bite humans and is sometimes found living in human dwellings. Species of Oeciacus live on swallows and martins, Cimexopsis nyctalis live on chimney swifts, and Haematosiphon inodora live on poultry. The latter has been known to feed on humans and pigs as well.
