BED BUG – Cimex lectularius L.
ALIASES: – REDCOATS, WALL LOUSE, ETC.
Do You Know?
The common bed bug has been feeding upon the blood of humans since the beginning of recorded history. A specimen of bedbug found at Tell el-Amarna in Egypt is the earliest record of its association with human beings. The presence of bedbug in the Mediterranean region was recorded by Aristophanes, Aristotle, and Dioscorides. With the expansion of commerce and civilization bedbugs spread throughout Europe and Asia. Bedbugs were subsequently reported in Italy (77 CE), China (600 CE), Germany (11th century), France (13th century) and England (1583 CE). Increasing urbanization and improvement in housing quality further led to the post-medieval spread of bedbugs since the late sixteenth century.
The earliest records of bed bugs in India were found in 7th– 8th century CE and later they were mentioned quite often in the modern Indian literature of the eighteenth and the nineteenth century.
DESCRIPTION – These relatively small insects are approximately 3/16-inch long (5 mm) and 1/8-inch wide. They are broadly oval, flat, brown to reddish-brown true bugs with a 3-segmented beak, 4-segmented antennae and vestigial wings. Bed bugs have very thin, vertically flattened bodies covered with short, golden-coloured hairs.
KEY SIGNS OF INFESTATION – Early detection of bed bugs is critical when performing an inspection. Common signs of infestation include:
- Shed Or Cast Skins
- Faecal Deposits (Dried Excreted Blood)
- Bed Bug Carcasses
- Egg Deposits
- Live Bugs
FACT – During the early stages of an infestation, bed bugs tend to be located in very close association to beds and/or upholstered furniture. As populations increase in age and size, however, the likelihood of finding bed bugs in unpredictable areas away from the host-feeding sites also increases.
