Adult female bed bugs lay eggs in secluded places. They can lay multiple eggs per day and hundreds in their lifetime. Adult females can also feed on warm-blooded animals to lay eggs. The eggs are about the size of the speck of dust, white in color, and incredibly hard to see without magnification. They are sticky when they are initially laid and easily stick to surfaces. It takes about a week for these eggs to hatch at room temperature. If nymphs have access to a supply of blood, they can grow mature in almost a month and multiply in numbers.
