What Are Bed Bugs?

 Bed bugs, known scientifically as Cimex lectularius (Cimicidae) are small wingless insects that feed by hematophagy - exclusively on the blood of warm blooded-animals. As we are warm-blooded animals we are ideal hosts for them. Over millions of years bed bugs have evolved as nest parasites - inhabiting the nests of birds and the roosts of bats. Some of them have learnt to adapt to the human environment and live in our nests, i.e. our homes, and more specifically, our beds. Newborns, called hatchlings or nymphs, are tiny, about the size of a poppy seed, while adults grow to about ¼ of an inch long. Their shape is oval and flattened. Both nymphs, eggs and adults are visible to the naked eye.

They are called bed bugs because of their preferred habitat in human homes: sofas, bed mattresses and other soft furnishings.

Bed bugs are seen as a growing problem within all types of dwellings, including private homes, dormitories, cruise ships, army barracks, and shelters.

When seen close up they may have a white, light tan to a deep brown or burnt orange color. Just after molting most of them are plain white. When they have had their feed a dark red or black blob may be observed within their body. They will instinctively seek shelter in dark cracks and crevices when disturbed.
