German Cockroach

The German cockroach is the number one roach in the world. These insects are particularly associated with restaurants, food processing facilities, hotels, and nursing homes. In colder climates, they are found only near humans, since they are not very tolerant to cold. Professional pest control can help you make sure you won't be cuddling up to a German cockroach this winter.

Pest Identification:

Size

5/8 in.

Color

Light brown to brown with two dark brown markings on the thorax.

Body Structure

Narrow oval-shaped body with long antennae and longitudinal markings on the thorax.

Characteristics

Extremely fast breeders, German cockroaches can produce as many as 6 generations of offspring in a year. The female produces an egg capsule about once every 25 days. The capsule contains anywhere from 1 to 4-dozen eggs. After eggs hatch, the nymphs mature into adulthood in as little as 3-4 months. The total lifespan of an adult German cockroach is about 1 year. Although the species has fully-developed wings, German cockroaches are incapable of flight; however, they can glide short distances if it feels threatened.

Habitat & Behavior

Like other roaches, the German cockroach is omnivorous. They prefer warm, moist conditions, which is why they often are found in kitchens and bathrooms, hiding in crevices and cracks. Because they are prolific reproducers and have few natural predators, German cockroach infestations can grow rapidly. German cockroaches are the most typical invaders of apartments, restaurants, grocery stores and anywhere food is prepared.

Prevention & Treatment

Along with sealing cracks and crevices where the German cockroach can enter your home, making sure food preparation areas are clean will help prevent infestation. Likewise, clearing clutter such as newspapers or piles of clothes is also suggested since German cockroaches are omnivorous scavengers who will eat anything, including paper and cloth. Because German cockroaches reproduce quickly, do-it-yourself treatments are not recommended. Roach bombs can be toxic and highly dangerous for humans and pets alike if administered incorrectly. If you believe you have a roach infestation, contact a pest control professional to identify the species and administer proper treatment. Find out more about roach extermination options.
