How long do female German cockroaches carry their egg capsules before the eggs hatch?

Female German cockroaches carry their egg capsules, known as oothecae, for about 1 to 2 days before they hatch. This brief period is crucial for the development of the embryos within the capsules. After carrying the ootheca for this short time, the female typically deposits the egg case in a safe location to protect the developing nymphs from predators and environmental hazards.

The other options present longer durations than what is typical for German cockroaches, which have adapted to ensure their young have the best chance of survival shortly after the eggs are laid. Understanding the reproductive habits of German cockroaches can help in developing effective pest control strategies, as knowing when the eggs will hatch can inform treatment timing and methods for managing infestations.
