Oriental roaches, also known as water bugs or black beetles, are a species of cockroach scientifically named Blatta orientalis. Understanding the biology of these insects can help in better managing and preventing infestations. Here are some key aspects of their biology:

Appearance: Oriental roaches are medium-sized cockroaches, typically measuring about 1 to 1.5 inches (2.5 to 4 cm) in length. They have a shiny, dark brown or black exoskeleton, which distinguishes them from other cockroach species. Males have wings that cover about three-quarters of their abdomen, while females have shorter wing stubs.
Habitat and Distribution: These roaches prefer dark, damp environments and are often found in areas with high moisture levels. They are commonly associated with sewers, basements, crawl spaces, and moist outdoor areas. Oriental roaches are found worldwide, but they are more prevalent in temperate regions.
Nocturnal Behavior: Oriental roaches are primarily nocturnal, meaning they are most active during the night. They are adept at hiding in cracks, crevices, and other dark, secluded areas during daylight hours.
Diet: As omnivorous scavengers, oriental roaches have a varied diet. They feed on decaying organic matter, including garbage, sewage, rotting vegetation, and even dead insects. In homes, they can also consume food scraps, pet food, and other organic materials.
Reproduction: The reproductive cycle of oriental roaches begins with the female producing an egg capsule, known as an ootheca, which contains multiple eggs. The female carries the ootheca until it is ready to hatch, after which she deposits it in a protected area. The nymphs hatch from the eggs and undergo a series of molts as they grow and develop into adults. The entire life cycle takes around one to two years.
Health Concerns: Oriental roaches are considered potential disease vectors. They can pick up pathogens and contaminate food and surfaces as they move through unsanitary areas. Their presence in homes can pose health risks and trigger allergies or asthma symptoms in sensitive individuals.
Prevention and Control: Preventing oriental roach infestations requires diligent sanitation practices and eliminating moisture sources. Repairing leaks, improving ventilation, and reducing humidity levels can discourage their presence. Additionally, sealing cracks and crevices and properly storing food can help prevent access and food sources.

These Oriental cockroaches are BIG. Second picture shows a roach with an egg case (ootheca) still attached. These roaches tend to be found areas of high moisture outside but sometimes, like in this case will come up thru sewer systems. You can find these in sinks and around floor drains, much like you would American Roaches.
