Bed Bugs, Cimex lectularius are parasitic insects of the cimicid family that feed exclusively on blood. The common bed bug is the best known as it prefers to feed on human blood.
The name bed bug is derived from the preferred habitat of Cimex lectularius; warm houses and especially nearby or inside 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 and allergic reactions.
Adult bed bugs are light brown to reddish brown, flattened, oval shaped and have no hind wings. They have segmented abdomens with microscopic hairs that give the appearance of being banded. Adults grow to 4-5 mm in length and 1.5-3 mm wide. Bed bugs can survive a wide range of temperatures at atmospheric conditions.
