German cockroaches are our most prolific cockroach species producing 3-6 generations per year. Besides its importance as a sign of poor sanitation used by health departments, the German cockroach has been implicated in the transmission of several pathogenic organisms and as a cause of allergic reactions for children and adults.
German cockroaches do not enter structures from outdoors, they are spread entirely by humans and live only indoors. The German cockroach is the major cockroach pest of residences, restaurants, warehouses and food-processing plants in the United States. German cockroaches spend most of their lives in cracks and protected void areas near sources of food and water.
The elimination of this pest is the desirable goal in any pest management program. This may include the use of growth inhibitors, baits, as well as residual insecticides specifically labeled for areas of food preparation.
