How many nymphal stages does a bed bug have in its life cycle prior to adulthood?

Bed bugs undergo a life cycle that includes a series of developmental stages known as nymphal stages, which occur between their egg and adult forms. Specifically, bed bugs have five nymphal stages before reaching adulthood. Each nymphal stage is distinct and requires a blood meal to molt into the next stage. The progression through these stages entails significant growth and maturation, culminating in the final adult stage that is capable of reproduction. Understanding the number of nymphal stages is crucial for pest control strategies, as each stage is vulnerable to different management practices, and recognizing these stages can aid in effective treatment planning.
