Step 1 : Introduction to the question "where do bed bugs come from"
Bed bugs are parasitic insects of the cimicid family that feed exclusively on blood. Cimex lectularius, the common bed bug, is the best known as it prefers to feed on human blood. Other Cimex species specialize in other animals, e.g., bat bugs, such as Cimex pipistrelli (Europe), Cimex pilosellus (Western United States), and Cimex adjunctus (entire Eastern United States).
Step 2 : Answer to the question "where do bed bugs come from"
Bed bugs can exist singly, but tend to congregate once established. Though strictly parasitic, they spend only a tiny fraction of their lifecycles physically attached to hosts. Once a bed bug finishes feeding, it relocates to a place close to a known host, commonly in or near beds or couches in clusters of adults, juveniles, and eggs—which entomologists call harborage areas or simply harborages to which the insect returns after future feedings by following chemical trails. These places can vary greatly in format, including luggage, inside of vehicles, within furniture, amongst bedside clutter—even inside electrical sockets and nearby laptop computers. Bed bugs may also nest near animals that have nested within a dwelling, such as bats, birds, or rodents. They are also capable of surviving on domestic cats and dogs, though humans are the preferred host of C. lectularius
Step 3 : Other interesting facts related to the question "where do bed bugs come from"
Eradication of bed bugs frequently requires a combination of nonpesticide approaches and the occasional use of pesticides. Mechanical approaches, such as vacuuming up the insects and heat-treating or wrapping mattresses, are effective. A combination of heat and drying treatments is most effective. An hour at a temperature of 45 °C (113 °F) or over, or two hours at less than −17 °C (1 °F) kills them; a domestic clothes drier or steam kills bedbugs. Another study found 100% mortality rates for bed bugs exposed to temperatures greater than 50 °C (122 °F) for more than 2 minutes. Next Step : We care our friends, so we share answers.
