The history of the bedbug offers clues to why bed bug bite people, but don’t typically cause us severe health problems.
Bedbugs are thought to have evolved from insects that dwelled in caves, feeding on bats and swallows. When humans in certain parts of the world, especially in colder climates, moved off of the plains and into the same caves, bed bugs seemed to change preferred hosts and began feeding on humans as well. Early cave drawings seem to illustrate man’s interaction with the nocturnal pest, depicting people being awoken by tiny, crawling creatures.
Humans are nearly ideal prey for bed bugs. We have less hair than other mammals, which bed bugs prefer. Direct access to skin makes their feeding much easier. Based on historical research, scientists believe the parasite thrives at a temperature between 60 and 70 degrees, so rather than reside on its host, it feeds and returns to the cool, dark hiding places that it favors. More recent research at Virginia Tech indicates that consistently cooler temperatures may expand the lifespan of bed bugs. Human dwellings give bed bugs a perfect combination of a reliable food source and convenient, nearby harborage in cooler spots in mattresses, box springs, behind wooden headboards, in couch cushions and other furniture. Though not rapid breeders compared to many other pests, a bed bug population left untreated can become a critical problem in a matter of months.

Today, beg bugs are one of the few parasites that feed almost exclusively on human blood. This exclusive relationship may be one reason they don’t seem to cause disease in human hosts. They may bite the hand that feeds them, but they seem to do so without jeopardizing their food source.Bed Bugs invade Tampa, St.petersburg and Clearwater.
