Cockroaches are typically nocturnal insects appearing only during the day when disturbed or when there is an excessively large infestation. Cracks and crevices are favored hiding and breeding areas. In the Pacific Northwest there are four cockroach species that may be encountered in structures. Each species prefers different areas of a structure in which to live and hide. Because various combinations of these cockroaches may occur in a building at the same time, it is essential to accurately identify the species present before starting any control measures.Contact Us
The Brownbanded Cockroaches are very very active and the adults jump when disturbed. Only the males can fly. Adults live from 3 to 11 months. Brownbanded cockroaches are more apt to be found in private residences than in commercial buildings, and are more common in eastern Washington than western Washington. Both nymphs and adults prefer to hide in warm areas near the ceiling, behind wall decorations and loose wallpaper, in closets, beneath or inside upholstered furniture, and in electrical appliances such as television sets, stereos, and toasters. The cockroaches may infest any room within a dwelling. It is important to note, thorough treatments from a Pest Fighter (or pest control operator) are important to remove the brownbanded cockroach infestation.
The American Cockroach is the largest cockroach species that infests dwellings in the Pacific Northwest. The adult is 1 1/2 inches long, reddish-brown to brown, with a light yellow or tan band around the edge of the shield behind the head. Both sexes have well-developed wings and can fly. The American cockroach is rare in the state of Washington, and most infestations are brought in with produce or in the furniture of persons moving from warmer climates, such as the southern United States. When established, the roaches prefer warm, moist environments.
The Oriental Cockroaches feeds on a wide range of decaying organic matter and has the reputation of being the filthiest of the household-infesting cockroach species. This pest is relatively uncommon in Washington and is most often found in the eastern part of Washington state. It is more commonly found in restaurants and other commercial buildings than in residences. It tends to prefer cool, moist areas wherever it occurs.
The German Cockroach is the most commonly encountered cockroach in apartments, restaurants, hospitals, or other buildings in which food is stored, prepared, or served throughout the Pacific Northwest. The pest is less common in private homes in western Washington, a bit more common in private homes in western Washington. Because the German cockroach produces more eggs and has more generations per year (three to four) than other cockroaches, a troublesome infestation can rapidly develop after the introduction of a few individuals. These cockroaches are often accidentally introduced into buildings with groceries (especially bagged potatoes and onions), beverage cartons and cases, and used furniture and appliances. In the Pacific Northwest and the Greater Seattle area, most migration occurs along plumbing or utility tunnels or between apartments in structures. Because of this tendency to migrate, adjacent apartment units should be checked for roaches. It also may be necessary to spray adjacent units to protect them from infestation. German cockroaches normally inhabit the kitchen and bathroom but will also occur in other rooms, especially if infestations are heavy.
During the day, adults and nymphs may be found hiding clustered closely together under, around, or even in the insulation found in the walls of appliances such as stoves, refrigerators, and dishwashers; around sinks (especially in the dead space between the sink and wall); beneath or around water heaters; in cracks around, under, or inside cabinets, closets, and pantries; and behind baseboard moldings. Other places to check include telephones, toasters, cash registers, coffee makers, and credit card imprinters, and behind pictures, wall hangings, or electric clocks.
