German Cockroach Life Cycle: How To long German Roaches Live? 

The German cockroach goes through three life stages: egg, nymph, and adult. The eggs hatch into nymphs, which are smaller versions of the adult cockroach. Nymphs molt, shedding their exoskeletons as they grow larger. They typically molt six times before reaching adulthood

German Cockroach Early Life 

The early life of a German cockroach starts with the egg stage. Female German cockroaches carry an ootheca containing 30-40 eggs until they are ready to hatch. After hatching, the immature German cockroaches, known as nymphs, emerge from the egg cases. Nymphs are wingless and look like smaller versions of the adult German cockroach. They molt, or shed their exoskeleton, as they grow larger. 

They are also highly sensitive to environmental conditions such as temperature and humidity, which can affect their growth and development.

German Cockroach Growing Up

As the German cockroach nymphs grow, they undergo a series of molts in which they shed their exoskeleton and develop larger and more complex body structures. During the first instar, or developmental stage, the nymphs are small and mostly translucent, with a white stripe down their backs.

 In the second instar, they start to develop darker pigmentation and begin to resemble miniature versions of adult German cockroaches. By the third instar, they have grown considerably and have well-developed legs, antennae, and wings. They continue to molt and grow in size and complexity until they reach the adult stage.

A Day In The Adult German Cockroach’s Life

The adult German cockroach is primarily active at night and spends most of its time searching for food, water, and mates. Here is a general outline of a day in the life of an adult German cockroach:

Resting: During the day, adult German cockroaches tend to rest in dark, warm, and humid areas such as cracks and crevices, under appliances, and in the voids of walls and ceilings.

Foraging: As night falls, the adult German cockroach becomes active and begins to search for food. They are opportunistic feeders and will eat almost anything, including grease, sugar, meat, and even cardboard and glue. German Cockroach Life Cycle

Water-seeking: German cockroaches also need water to survive and will actively seek out sources of moisture such as dripping pipes, condensation, and standing water.

Mating: Adult German cockroaches are also active in seeking out mates. Males produce a pheromone to attract females, and after mating, the female will carry the egg capsule, or ootheca, until it is ready to hatch.German Cockroach Life Cycle

Avoiding danger: German cockroaches have a strong aversion to light and will quickly scurry away when exposed to it. They also have an acute sense of danger and will detect and avoid any potential threats or hazards.

German cockroaches are highly adaptable insects that can survive for extended periods without food and water, although their lifespan in such conditions can vary depending on several factors such as age, sex, temperature, and humidity. In general, adult German cockroaches can survive for up to a month without food, and for up to two weeks without water.

Moreover, German cockroaches can still be attracted to even the smallest amounts of food and water, so it’s crucial to practice good sanitation and hygiene measures to prevent infestations and reduce their chances of survival. This includes regular cleaning, proper 

storage of food and waste, and fixing any water leaks or moisture issues in your home.

A female German cockroach can lay up to 40 eggs at a time in a protective egg capsule called an ootheca. She can produce several oothecae in her lifetime, which can contain up to 50 eggs each

German cockroach eggs usually take about 28 days to hatch, although the hatching time can vary depending on environmental conditions.

German cockroaches have an average lifespan of about six months to one year, although this can vary depending on environmental conditions and other factors.

Signs of a German cockroach infestation include sightings of live cockroaches, egg capsules, shed skins, fecal matter, and a musty or oily odor. German cockroaches are often found in areas with access to food, water, and warmth, such as kitchens, bathrooms, and laundry rooms.


The German cockroach life cycle involves three main stages: egg, nymph, and adult. The eggs hatch into nymphs, which go through several molts and growth stages before reaching adulthood. German cockroaches are highly adaptable and can reproduce quickly, making them a common pest in homes and businesses. Effective management of German cockroach infestations requires an integrated pest management approach that addresses sanitation, exclusion, baiting, and insecticide treatments.German Cockroach Life Cycle
