All About Oriental Roaches

Oriental Roaches Identification Guide

Physical Characteristics

Oriental roaches, commonly known as “water bugs,” are large, dark brown to almost black in color, and grow to about 1 to 1.25 inches in length. Unlike other roaches, they have a shiny, almost oily appearance. Males have short wings that cover about three-quarters of their body, while females have even shorter, undeveloped wings. Neither can fly. They are slower-moving roaches compared to other species and are often found in damp, humid environments.

Common Species

Blatta orientalis (Oriental Roach) - The most common species found in basements, crawl spaces, and areas with high moisture.

Oriental Roaches Behavior and Biology

Oriental roaches thrive in damp, dark areas such as basements, sewers, and crawl spaces. They prefer cooler environments and are more active in the spring and summer months. Their diet consists of decaying organic matter, garbage, and food scraps. Unlike German roaches, they are not as dependent on indoor environments and can often be found outside under leaves, mulch, and in sewer systems.

How We Treat for Oriental Roaches

When treating for Oriental roaches, our technicians focus on the following steps:

• Inspection: A detailed inspection of basements, crawl spaces, and other damp areas to identify signs of activity such as droppings or live roaches.

• Treatment: Application of repellent and non-repellent insecticides inside and outside the home, targeting cracks, crevices, baseboards, and entry points.

• Moisture Control: We advise homeowners on reducing humidity by using dehumidifiers, fixing leaks, and sealing gaps around pipes and drains.

• Preventative Maintenance: Regular treatments to prevent future infestations, as Oriental roaches thrive in high-moisture environments.
