They are called cimicids or, loosely, bed bugs, though the latter term properly refers to the most well-known member of the family, Cimex lectularius, the common bed bug, and its tropical relation Cimex hemipterus.

Cimex hemipterus, known as the tropical bed bug, is a species of bed bugs within the family Cimicidae that primarily resides in tropical climates. However, it has been reported that this species can live in more temperate climates along with the closely related bed bug species C. lectularius. [1]

The male bed bug aedeagus has been shown to carry five (human) pathogenic microbes, and the exoskeleton of female bed bugs nine, including Penicillium chrysogenum, Staphylococcus saprophyticus, Stenotrophomonas maltophilia, Bacillus licheniformis, and Micrococcus luteus. Tests with blood agar have shown some of these species can survive in vivo ...
