German cockroaches are extremely fast breeders, producing as many as six generations of offspring in a single year. Females produce an egg capsule about once every 25 days. The capsule contains anywhere from 1 to 4 dozen eggs. After the eggs hatch, the nymphs mature into adulthood in as little as 3-4 months. The total lifespan of an adult German cockroach is about one year.

German cockroaches are most active in the summer months due to their affinity for heat and humidity. Under the right conditions though, they can survive year-round inside homes and commercial establishment.

German cockroaches do not live outdoors. They prefer warm, moist conditions, which is why they are often found in residential and commercial kitchens and bathrooms. They are particularly associated with restaurants, food processing facilities, hotels, and nursing homes.

Like other types of cockroaches, German cockroaches are omnivorous scavengers that will eat anything including all kinds of food, paper, and cloth.

Roaches don’t bite, so they can’t hurt you in this way, but they can spread human pathogens, diseases, and bacteria. They will pick up germs on their legs and transfer them to everything they touch. If they get into your food, they will contaminate it. Their feces is also known to cause allergic reactions, especially in children and people with asthma.

German cockroaches do not enter structures from outside. Typically, they are carried in albeit unknowingly in grocery bags, cardboard boxes, and even on secondhand appliances. Once inside, they’re likely to stick around if they can locate warm and humid hiding spots close to food and water sources.

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.
