Oriental cockroaches grow to be about one inch in length and they are shiny black in color.  Females have wide bodies and undeveloped wings while males have narrower bodies and developed wings. Oriental cockroaches are not capable of flight.

Another distinctive feature of these roaches is that they emit a very pungent, musty odor.

Are Oriental cockroaches dangerous?

Like any other species of roach, Oriental cockroaches are very dangerous to have invading your home; allergens from Oriental cockroaches can trigger allergic reactions and asthma attacks in people, especially in young children.

Before entering into your home these pests are crawling through garbage and sewage; because of this Oriental cockroaches carry and spread dangerous bacteria, human pathogens, and parasitic worms from their bodies and legs. Inside of homes Oriental cockroaches contaminate food sources, utensils, dishes, and food prep areas with bacteria and pathogens.

Why do I have an Oriental cockroach problem?

Oriental cockroaches live outside in moist, dark areas like in sewers, under piles of leaves and other organic debris, under stones, and underneath piles of wood and fallen logs.  If the weather outside becomes too hot and dry for them they will actively seek shelter indoors or they may accidentally find their way inside while foraging for food (starchy foods and any type of organic matter).

Oriental cockroaches typically enter through spaces found underneath of doors, through the spaces found around utility pipes and through pipes and floor drains.
