How are cockroaches harmful?
German cockroaches are the most common household insect within the United States. This pest typically infests kitchens and bathrooms, yet will live anywhere inside heated structures in which food, water, and harborage are available. German cockroaches feed on any type of human food, contaminating it and spreading disease.
How do I identify the different types of cockroaches?
Adult cockroaches are about 1/2" to 5/8". Their color variation is usually brown to tan. The pronotum has two dark parallel bars on it. Adult males are somewhat narrower than the females when viewed from below. Thy nymphs, 1/8" long when they emerge from the egg capsule, are almost uniformly dark except for a light tan area on the back of the second and third segments.
