Oriental Cockroach (B. Orientalis)
Features
Oriental cockroaches are also known as water bugs or black beetles, since they prefer:
• Dark, moist places e.g. drains, sewers, sludge trenches, firewood, basements, garages, garbage containers, moist areas under houses.
• Green areas where individual families accommodate, landscapes, and open areas where people feed their pets.
• Cold places more than other species, especially in fenced buildings.
Oriental cockroaches can infiltrate into houses and buildings, searching for foods; they normally stay in ground floors; they move more slowly than other species.
Oriental cockroaches do not fly and cannot climb horizontally the smooth and vertical surfaces. We can find them in porcelain tubs and pipelines. Adult cockroaches have a lifespan of 140 days and produce 8 egg sacks.
