Quick Summary

Cimex pilosellus is a species of true bug in the family Cimicidae, commonly known as a bat bug. While it primarily feeds on bats, it is capable of biting humans and can sometimes be found in human dwellings. These insects are characterized by their reddish-brown, flattened bodies, typically measuring 4 to 5 mm in length, with non-functioning, vestigial wings. They possess scent glands that produce a distinctive oily odor. Female bedbugs lay around 200 eggs, and multiple generations can occur annually. Despite their irritating bites, bedbugs are not known to transmit diseases to humans. Infestations have become a global concern due to increased travel and pesticide resistance.1
