"If you were to view a picture of a bed bug, it would vary depending on the bedbug life stage and whether or not the bedbug has just fed on a human host. The bed buy life cycle and pictures from each stage is depicted below. Bed bug eggs are 1/32 inches long and are white in color. A female can lay batches of 10 to 50 eggs at a time. The eggs hatch in 6 to 17 days in average temperatures, but as long as 28 days if temperatures are cool. Eggs are not laid if the temperature is below 50F. Baby bed bugs molt 5x, feeding between each molting stage. This period, where they are referred to as nymphs, lasts approximately 6 weeks. Bed Bugs can create 3 generations in one year if temperatures indoors are around 70F. Adults are 1/4 to 3/8 inches."
Bedbugs move through 10 stages during their life cycle as depicted below; from egg to adult. The appearance changes with the egg being a small white object the size of a pinhead, to small brown straw colored nymph to reddish/brown adult. It takes approximately 10 months for the lifecycle to be complete. Bedbugs need to feed to move from 1 stage to the next.
This shows a collection of bed bug eggs. The eggs
are usually laid on a corrugated or rough surface such as fabric and
adhere to the surface with a cement like substance. Eggs
cannot be killed with spray products, as the spray will not penetrate
the shell of the egg.
The most effective way to kill them is with a hand steamer such as the one offered for this purpose by Bed Bug Patrol , which uses heat at 120F, which will kill both eggs and live bedbugs. Bed Bug Patrol also offers a kit that is an economical way to purchase all the products needed to remove these pests.
Adult bed bugs are flat and approximately 1/4 inch in length. Their size will grow by approximately 1/3 after feeding as depicted on the right.
One way to determine if you have Bedbugs is to look at them
from a side view. They are very thin from the side.
Another way to determine if you have bedbugs is to send a
sample to Cornell Insect Diagnostic Lab filling out this form
There is a $25 fee for this service payable to Cornell University.

To move through their life cycle bedbugs need to feed at each stage. They will feed one time every two weeks for approximately 10 minutes, and with each feeding the picture of a bed bug changes. They don't actually bite the skin, but puncture it with two tubes that are connected to their head. Some people will have a hypersensitive reaction to proteins in the saliva the bedbug leaves behind, which leaves a small red papule, or red inflamed area around a clear center.
