(6 mm) long. They emit an unpleasant-smelling oily secretion from two glands on their undersurface. All are parasites of warm-blooded animals. The common human bedbug of temperate regions, Cimex lectularis, is largely nocturnal, spending the day in crevices in walls and furniture and in bedding. Its bite causes irritation in many individuals, but it is not known to transmit diseases. It will feed on other mammals and poultry when humans are not available and can live up to a year without feeding. Maturation from egg to adult takes about two months in warm conditions; there may be three or four generations a year. Control methods include steaming, spraying, and fumigating. Another parasite of humans, C. hemipterus, is common in the Old World tropics. A North American species, Haematosiphon inodora, parasitizing poultry, will also bite humans. Other species attack bats and various kinds of bird. Bedbugs are classified in the phylum Arthropoda Arthropoda [Gr.,=jointed feet], largest and most diverse animal phylum. The arthropods include crustaceans, insects, centipedes, millipedes, symphylans, pauropodans, and the extinct trilobites. .....
