Bed bugs are small, nocturnal, wingless insects that belong to the family of
Cimicidae. A newly hatched bed bug is semi- transparent, light tan in color,
and the size of a poppy seed. The adult bed bug does not have any wings
and has a flattened body. They are about the size of an apple seed.
They feed on human blood and other warm-blooded hosts.
They are oval in shape and grow up to 4-5mm long when fully grown.
Not only are they dorsoventrally flattened, but they are also thin which creates a great advantage for them. They can hide in unusual places such as behind baseboards, floor cracks, and under carpets or behind loose wallpaper, which makes them difficult to detect.
Not only are they undetectable, but bed bugs also tend to stay close together and have a distinctively sweet, yet unpleasant smell. Blood spotting on mattresses and nearby furnishings are also signs of a bed
bug infestation. Bed bugs can be easily confused with other small household
insects, including carpet beetles, spider beetles and newly hatched cockroaches
Bed bugs have existed since the ancient times and are found in temperate
climates throughout the world. There are different types of bed bugs, but the
common bed bug with a scientific name of Cimex lectularius, is adaptable to
In tropical regions, including Florida, other visible kind of species called Cimex
hemipterus, are also known to swarm among poultry and bats. Other places,
such as West Africa and South America, are home to the Leptocimex boueti
species that infests bats and humans. On the other hand, the species that are
found among bats are called Cimex pilosellus and C. pipistrella, and are lurking
all over in North America, primarily in poultry farms.
Since they can survive in birds' nests, they can be seen in houses and buildings
that have several bird nests, particularly on rooftops. They are also known to
feed on bats or household pets, but their typical source of nutrition is human
Bed bugs have a great worldwide distribution due to human travelers who
transport 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
