Bed bugs are small, nocturnal, wingless insects that belong to the Cimicidae family. They feed on human blood and other warm-blooded hosts. Bed bugs are also known as “mahogany flats,” “red coats” and “chinches.” The adult bed bug does not have wings and has a flattened body.
Bed bugs are at an advantage because they are dorsoventrally flattened and thin. They can hide in cracks and crevices like no other. Bed bugs can be found in many places other than beds, such as behind baseboards, floor cracks, and under carpets or behind loose wallpaper. Not only can they be hard to detect, but bed bugs also tend to stay close together and have a distinctively sweet, yet unpleasant smell. Their bites can leave itchy welts on the skin and can cause allergic reactions, though not everyone reacts to their bite.
Bed bugs have existed since the ancient times and are found throughout the world. There are different species of bed bugs, but the common bed bug (Cimex lectularius) is particularly adaptable to human environments. Other species are known to prefer birds and bats but also will feed on humans if necessary. Since they can survive in birds’ nests, they can be seen in houses and buildings that have several bird nests, particularly on rooftops. Bed bugs have a great worldwide distribution, due to human travelers who transport them in luggage, clothing, bedding and furniture. Though they may reside in unusual places, they are also likely to be found in small cracks near a bed or in comforters and bed sheets.
