Bed bugs (Cimex lectularius) are nocturnal insects which come out at night to feed on the host’s blood (yourself). Sometimes these bed bugs are mistaken as dust mites. They’re flat and oval in shape that resembles something similar to an apple pip. They are small enough to squeeze in between paper-thin gaps and move quickly. They’re great at hiding out until the morning hours come, so be prepared to tackle the infestation during the day when they emerge.
