What Do Bed Bugs Look Like?

Bed Bugs are small, flat, wingless insects with six legs that, just like mosquitoes, feed on blood from animals or people. New-born bed bugs, referred to as hatchlings or nymphs, are tiny but visible and about the size of a poppy seed. Adults grow to about 0.25 inches long with an oval and flattened shape to their bodies when they are not feeding.

After feeding, they can double in size. Nymphs, eggs, and adults are visible to the naked eye. Their colour may range from a white, light tan to a deep brown or burnt orange colour. When they have fed, a dark red or black blob of blood is visible within their once flattened bodies.
