Bed Bug
Bed bugs are parasitic insects of the cimicid family that feed exclusively on blood. The term most commonly refers to members of the genus Cimex of which Cimex lectularius, the common bed bug, is the best known as it prefers to feed on human blood although other Cimex species are specialized to other animals, e.g., bat bugs, C. pipistrelli (Europe), C. pilosellus (western US), and C. adjunctus (entire eastern US). The name of the "bed bug" is derived from the preferred habitat of Cimex lectularius: warm houses and especially nearby or inside of beds and bedding or other sleep areas. Bed bugs are mainly active at night, but are not exclusively nocturnal. They usually feed on their hosts without being noticed.
A number of adverse health effects may result from bed bug bites, including skin rashes, psychological effects, and allergic symptoms. Diagnosis involves both finding bed bugs and the occurrence of compatible symptoms.
Bed bugs have been known as human parasites for thousands of years. At a point in the early 1940s, they were mostly eradicated in the developed world, but have recently increased in prevalence since 1995. Because infestation of human habitats has been on the increase, bed bug bites and related conditions have been on the rise, as well.

Famous quotes containing the word bed:
“Professor: War is hell, Mr. Thornhill, even if it’s just a cold one.
Roger Thornhill: If you fellows can’t lick the Vandamms of this world without asking girls like her to bed down with them, and fly away with them, and probably never come back, perhaps you ought to start learning how to lose a few cold wars.
Professor: I’m afraid we’re already doing that.”
