Description: This image depicted a dorsal view of Cimex lectularius, a bed bug nymph, as it was in the procedure of swallowing a food source from the arm of a “volunteer” human host that could be seen filling the belly of the pest. Bed bugs, in nature, are not carriers of any known human disease. Although some illness organisms were recovered under laboratory settings from bed bugs, none of them were shown to be distributed outside the laboratory by bed bugs. Globally, the common bed bug is found. Infestations, occurring in settings of unhygienic housing conditions and severe crowdedness, are common in the developing world. Bed bug infestations became rare in North America and Western Europe during the second half of the 20th century and have been seen as a condition that occurs in travelers returning from underdeveloped nations. Anecdotal reports, however, suggest that in the United States, Canada, and the United Kingdom, bed bugs are increasingly prevalent. It may take many months for a juvenile bed bug to mature into an adult, and an adult bed bug can live for up to one year. The youthful bed bug will feed frequently on human blood during growth, and can exist between blood meals for many months. To thin out the blood and to prevent coagulation, bed bugs inject saliva into their host’s blood stream. The intense itching and welts are caused by this saliva. The delay in the beginning of itching provides time for the feeding bed bug to escape into cracks and crevices. The itchy bites may develop into painful welts that last several days in some instances. The common bug C for the bed. Lectularius is a blood-sucking, wingless, red-brown insect that grows up to 7 mm in length and has a lifespan of 4 months to 1 year. In beds, wooden furniture, floors, and walls, bed bugs hide in cracks and crevices during the daytime and emerge at night to feed on their preferred host, humans.
