What Do Bed Bugs Look Like?
Bed Bug Illustration
Bed bugs have small, flat, oval-shaped bodies. They are wingless and covered in small hairs that make their bodies appear to be striped.
Adults are brown in color, although their bodies redden after feeding. Full-grown bed bugs move slowly and measure between 1/8 and 3/16-inch, making them visible to humans.
