Where can they be found?
The C. Lectularius is predominantly seen in temperate regions while these tropical bed bugs, as their name suggests, are seen in tropical or warmer regions including southern states of USA as well as countries in Asia and Africa.
How do they look?
Both species of the Cimicidae family are small, flat and oval shaped. Although, their bodies are reddish brown in color; the adults typically measure about quarter of an inch to 5/8th of an inch in length. The nymphs/larvae and adult bed bugs are equipped with special mouth parts that enable them to draw blood from their warm-blooded hosts. Both varieties are incapable of flight as they are wingless.
Biology of the Bug
As the female bed bug lays her eggs (i.e., one to five per day and 200-500 within her lifetime); she uses a clear substance to attach them on cracks and on rough surfaces. Under ideal conditions, eggs hatch in about 10 days and the nymphs molt five times, taking a blood meal between each molt. Development time from egg to adult is 21 days. Adult bed bugs can live for almost one year.
The tropical bed bugs do not like light; they hide in cracks to avoid it during the day. Furthermore, they are known to prefer wood, paper, wall plaster, textiles and linen for their harborages. Also, while feed at night and take nearly 3-5 minutes to engorge on the host’s blood. After this, they return to their hiding places. The Cimex Hemipterus can travel up to 20 feet from their harborage to the sleeping hosts.
Tropical bed bugs have been reported in various types of dwellings in the US, including small or multifamily homes, five-star hotels, motels as well as airplanes, buses, day care centers etc.
