bedbug, (family Cimicidae), 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.
In the early 21st century, bedbug infestations became a growing problem worldwide. The rise was due, in part, to greater global transportation as well as the bugs’ increasing resistance to pesticides. To prevent infestations, experts have recommended vacuuming suitcases after vacations and thoroughly inspecting used furniture or bedding items before bringing them into the home. In addition, individuals should regularly examine areas where bedbugs typically live, such as couches and beds.
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; members of Cimexopsis nyctalis live on chimney swifts; and those of Haematosiphon inodora live on poultry. Bedbugs of the latter species have been known to feed on humans and pigs as well.
