Shiny black to a dark reddish-brown color, oriental cockroaches are a pest invader that most frequently gains entry beneath the thresholds of doors, through open doors or gaps beneath siding, even following utility lines, pipes, open drains or sewers into a structure or home. The adults of the oriental cockroach are very different in appearance. The smaller adult male oriental cockroaches, reaching only a length of 25 mm, can be identified by the presence of three-quarter-length wings, leaving the last few abdominal segments exposed. The larger adult female oriental roaches, reaching a length of 32 mm, on the other hand, lack wings altogether, having only large wing pads that cover the first couple of segments of the body. Neither the male nor female is capable of flight. Primarily an outdoors species, oriental cockroaches are well adapted for surviving in the natural environment. Most outdoor populations can be found living beneath the mulch in landscape beds, in leaf litter, beneath stones or debris outdoors. If access is available, the insects can thrive in the voids or openings beneath porches, in wall voids and crawlspaces. In more metropolitan areas, oriental roaches can be found in large numbers living in storm drains and sewers. Oriental cockroaches are known for their preference of feeding on garbage, filth or material that has begun to decay. These cockroaches are very dependent upon water. While studies have shown that they can survive for up to a month without food, these insects can not survive for more than two weeks without water.
How to get rid of Oriental Cockroaches
Before deciding how to kill roaches in your home, it is best to develop a plan. The most effective roach control typically requires more than one type of treatment method.
Caulk all penetrations through ground level walls.
Stop water leaks, screen equipment overflow drains, and take overflow water away from buildings; keep drain traps full or capped.
