Where do oriental cockroaches tend to cluster?

Oriental cockroaches are drawn to environments that provide moisture and shelter, which is why they tend to cluster in moist areas. They prefer dark, damp locations such as basements, bathrooms, and kitchens, where they can find the humidity they need to thrive. These insects are less attracted to light, which sets them apart from some other cockroach species. Additionally, the moisture not only supports their survival but also provides a suitable habitat for their lifecycle. They do not typically isolate themselves in high, open spaces or near bright lights, nor do they specifically cluster around food packaging unless the packaging is in a location that meets their moisture requirements. Thus, the choice highlighting moist areas accurately reflects the behavior and preferences of oriental cockroaches.
