Shed Exoskeletons or Eggs
As bed bugs mature and move through their different life stages, they will begin to shed exoskeletons on bedsheets and other surfaces near their food source. This process is called molting. These casings are even smaller than adult bed bugs, but since they are stationary, they can be easier to spot than live bed bugs.
Bed bug eggs may also be present. Once a female bed bug has grown from a nymph to an adult, she will begin to lay eggs. A female can lay anywhere between 3-8 eggs per week. Bed bug eggs are very small and look like tiny creamy-white specks.
