What do bed bugs look like?
Bed bugs are small insects with oval shaped bodies, six legs and two antennae. Their coloration will vary depending on their age as well as whether or not they have fed recently. View the bed bug pictures to get a better look at the shape, size and color variations. Nymphs (young bed bugs) are semi-translucent. When they feed they fill with blood, making their belly a dark brown and sometimes causing a spotted pattern where the blood is visible inside their abdomen. Adult bed bugs will be either a light brown with a flat, oval belly if unfed or a deep brown/red color with an engorged belly if they have fed.
