The Oriental cockroach is a large roach reaching about 1 inch in length.
They are very dark brown to black. Females are oval shaped and have short stubby wings. Males have wings that do not reach the end of the abdomen.
Oriental roaches are commonly known as “water bugs” and can be found living outdoors in damp locations such as underground water and sewage systems. Their travel through such unsanitary habitats increases their potential as disease vectors. They often enter structures by crawling under doors or through other exterior openings and often take up residence in damp basements, cellars, crawl spaces, near drains, leaky water pipes and beneath refrigerators, sinks and washing machines, under floors, and inside walls. Oriental cockroaches are nocturnal, avoid light, and, although the male has well developed wings, neither sex can fly.
These insects feed on garbage and decaying organic matter and are often considered the filthiest of the house-infesting roaches.
Females carry their egg capsules for about one day, and then deposit the capsule in a secluded place. Each capsule has an average of 15 eggs. Eggs hatch in about 60 days and nymphs develop in about one year. Adult females live one to six months.
Oriental cockroaches can live without food for up to a month if water is present, but will die in two weeks without food and water.
Proper identification is key to eliminating any roach infestation.
