Size: Eggs are approximately 1/32 of an inch long while adults are approximately 1/4 to 3/8 of an inch long.
Color: Their eggs are white, while babies (nymphs) are colorless, and adults are a mahogany or rusty brown color.
Shape. All bed bugs are oval shaped and have six legs. Their feet have claws, not pads, making it harder for bed bugs to move about freely on slicker surfaces, such as plastic or metal.
Characteristics. Bed bugs are wingless insects that are flattened on the top and bottom with microscopic hairs that give the impression of a wrinkled appearance. After feeding, they become engorged with blood, increasing their body length and swelling at the sides while typically expressing a more dull-red or red-brown color.
