These large cockroaches are originally from the region of the Black and Caspian Seas.  They are often about an inch long, shiny, dark brown in color and oval shaped.  These cockroaches will eat scraps of food but prefer decaying organic matter and most often come into houses in search of water.  For this reason, these cockroaches are most often found in basements, crawl spaces or near sinks and in bathrooms.  They usually live outside in warmer months but may seek refuge in homes as the temperatures drop in late fall and winter.

Oriental cockroaches are flightless and possess only vestigial wings.  This contributes to them being slower and easier to catch than most cockroaches, but because they are not as dependent on human food scraps, they may be harder to find and eradicate.  Keeping surfaces clean and eliminating all standing water will help discourage their presence, as will sealing possible entry points around windows, pipes, and doors.
