what color are bed bugs

Bed bugs can have different colors depending on their feeding status. Adult bed bugs are usually brown in color, with a flat, oval-shaped body, and are about the size of an apple seed. When they have not fed recently, they are light brown, but when they have fed, their body elongates and becomes more balloon-like, and their color changes to a deep reddish-brown. Young bed bugs, also called nymphs, are smaller and nearly invisible to the naked eye if they have not eaten recently. They are usually a translucent or whitish-yellow in color unless they have recently fed, and then they are a red color.
