What characteristic feature does the Smoky brown cockroach possess when it comes to its eggs?

The Smoky brown cockroach is known for its distinctive reproductive behavior, particularly regarding its egg cases, also known as oothecae. Unlike some other species, the Smoky brown cockroach does not lay eggs individually or in water. Instead, it produces a single ootheca that contains multiple eggs, and this egg case is often glued together to create a more protective environment for the developing embryos.

This adhesive quality of the ootheca helps in adhering it to surfaces to prevent it from being swept away, thereby ensuring that the eggs have a greater chance of surviving until they hatch. The ootheca might be deposited in hidden areas where conditions are favorable for the young roaches to emerge.

In contrast, the other options do not accurately describe the behavior of the Smoky brown cockroach. This knowledge is crucial for pest control professionals to understand the nesting habits of this species when developing effective control strategies.
