Bat bugs, closely related to bed bugs, are ectoparasites primarily found in bat colonies. Scientifically known as Cimex adjunctus, these small insects can occasionally infest human dwellings, especially when bats roost in attics or wall voids. While they resemble bed bugs in appearance and behavior, understanding the distinct characteristics and habits of bat bugs is crucial for effective management and control. Addressing a bat bug infestation involves not only treating the bugs but also dealing with the underlying bat issue.
