Bed bugs feed on the blood of humans, and live where people sleep, rest or sit for long periods, such as living rooms and bedrooms. They emerge at night to feed quickly, then retreat back into hiding. After mating, females lay eggs, which hatch in about 6-10 days. A single bed bug can lay 1- 3 eggs per day, 200-250 eggs in her lifetime. Adults live about 10-11 months.
