Which sign of cockroach infestation is characterized by their eggs?

The presence of oothecae is a definitive sign of cockroach infestation. Oothecae are egg cases produced by female cockroaches, and they typically contain multiple eggs—often up to 50 or more, depending on the species. The appearance of these egg cases often indicates that a breeding population is present, as females carry the oothecae until the eggs are ready to hatch or they may drop them in a secure location.

In a sanitation context, observing oothecae is crucial because it signifies not only an ongoing infestation but also the potential for rapid population growth. Effective pest management strategies must then be implemented to address both the adult cockroaches and the eggs to prevent further infestation. Recognizing and understanding the implications of finding oothecae is essential for maintaining sanitary conditions on ships and ensuring compliance with health regulations.
