The key to exterminating large roaches like Oriental cockroaches is to kill the entire roach nest. If you just spray and kill the individual roaches that you see, you will continue to see roaches scampering around your home looking for food and water, and will most likely begin to see more of them and more frequently as they breed and the nest continues to grow. Combat® products provide the source kill you need and are a guaranteed solution!

Oriental Cockroaches are major household pests in parts of the Northwestern, Midwestern and Southern United States. Unlike most large cockroaches, they live in temperate regions and do not survive in tropical climates. They are sometimes called “black beetles” or “water bugs” because of their dark coloring and their preference for damp locations.
Oriental Cockroaches are large roaches. They are dark-brown to black in color and adults are approximately 1 to 1 1/4 inches long. Adult males have fully developed wings reaching 3/4 of the way down their backs, but do not fly. Females have undeveloped wings, which are reduced to small lobes.
Oriental Cockroaches are commonly found during the spring and summer in dark and damp areas outdoors. They typically invade homes through drains or small cracks and are commonly found in basements and crawl spaces. They will climb to upper floors and often climb into apartments through garbage chutes in multistory buildings.
Reduce access to the home or other structures by caulking cracks in exterior walls and installing screens in drains. Increase ventilation and sunlight by trimming back shrubs will discourage Oriental Cockroaches from settling in basements and crawl spaces. Decrease damp areas in the yard by limiting irrigation, improving drainage, and removing piles of wood, leaves, or other debris.
