What is the minimum number of nymphal stages a bed bug undergoes before reaching adulthood?

Bed bugs go through a systematic life cycle that includes several nymphal stages before they reach adulthood. Specifically, they undergo five nymphal stages, each of which requires a blood meal for growth and development. These stages allow the bed bug to progress from an immature form to its fully developed adult state.

Throughout these five nymphal stages, the bed bug sheds its exoskeleton during a process known as molting. After the final nymphal stage, the bed bug emerges as an adult, capable of reproduction. Understanding this life cycle is crucial for pest control, as it aids in determining effective strategies for eliminating bed bugs and preventing infestations.

The other options, which suggest a different number of nymphal stages, do not accurately reflect the biological development of bed bugs. Recognizing the correct number of stages helps in implementing effective pest management techniques tailored to disrupt their life cycle.
