What are bed bugs?

Bed bugs (Cimex lectularius) are small, brown, and flat-bodied bugs that feed on human or animal blood. They are about the size of an apple seed and after they eat, their bodies turn more bloated and red in color.

These small bugs can move quickly by crawling. Though they do have wings, they are not used for flying. Their bodies include a beak and 3 parts, an antenna with 4 parts, wings, and short hairs.

Bed bugs also have an odor that is made by glands on their bodies that smells musty and sweet.
