How long does the German cockroach carry its eggs before dropping them?

The German cockroach carries its egg case, known as the ootheca, for a period of approximately 27 days before depositing it in a protected location. This duration is critical as it allows the eggs to develop in a safe environment, increasing the chances of survival for the nymphs once they hatch. The German cockroach is known for its reproductive efficiency, and by carrying the eggs for this specific timeframe, they ensure that the young are well-formed and capable of surviving in their surroundings immediately upon becoming independent. Understanding the biology and life cycle of the German cockroach is essential for effective pest control and management strategies. The other durations presented do not align with the established biological knowledge regarding the reproductive habits of this species.
