How many moults do bed bug nymphs go through?

• A. 3
• B. 4
• C. 5
• D. 6

Answer: (C)

Bed bugs develop through a series of molts called instars. After hatching from an egg, a nymph goes through five successive molts before reaching adult size. Each molt adds to body size and typically requires a blood meal to allow progression. The life cycle is egg → first instar → second instar → third instar → fourth instar → fifth instar → adult. So, bed bug nymphs molt five times before becoming adults.
