How Long Do Cockroaches Live? A Comprehensive Guide to Cockroach Lifespan

by Derrick | Last Updated: June 10, 2023

Have you ever wondered how long cockroaches can live? These pesky insects are known for being resilient and surviving in even the harshest conditions. Cockroaches are found all over the world and come in different species, each with its own unique characteristics. Although they are often viewed as pests, they play an important role in the ecosystem, serving as a food source for other animals.

The lifespan of a cockroach can vary depending on the species and the environment they are in. On average, cockroaches can live anywhere from a few months to a couple of years. Factors that can affect their lifespan include temperature, humidity, and the availability of food and water. Some species, such as the American cockroach, can live up to a year as adults and produce an average of 150 young during their lifetime.

Lifespan of Cockroaches

Cockroaches are known for their resilience and ability to survive in harsh conditions. Their lifespan varies depending on the species and environmental factors. In this section, we will discuss the factors that affect the lifespan of cockroaches.

Factors that Affect Cockroach Lifespan


Different species of cockroaches have varying lifespans. For instance, American cockroaches live the longest, with a lifespan of up to three years. On the other hand, German cockroaches have a shorter lifespan of about 100-200 days. Knowing the species of cockroach you are dealing with can help you determine how long they are likely to live.

Environmental Factors

The environment plays a significant role in the lifespan of cockroaches. The availability of food, water, and shelter can affect their lifespan. Cockroaches that have access to a constant supply of food and water are likely to live longer than those that do not. Similarly, cockroaches that live in clean environments with little clutter are less likely to contract diseases and infections that could shorten their lifespan.


The reproductive capabilities of cockroaches can also affect their lifespan. Female cockroaches can lay hundreds of eggs during their lifetime, ensuring that their offspring continue the species. Cockroaches that reproduce at a faster rate are likely to have a shorter lifespan as they put more strain on their bodies.

In conclusion, the lifespan of cockroaches varies depending on several factors, including species, environmental factors, and reproduction. Understanding these factors can help you control their population and prevent infestations.

Cockroach Species Lifespan

When it comes to cockroach lifespan, it varies depending on the species. Here are some details about the lifespan of three common cockroach species:

American Cockroach Lifespan

The American cockroach has the longest lifespan of all cockroach species, living up to three years. However, this is only possible if they are living in optimal conditions and are not exposed to any external factors that could cause their death. American cockroaches can survive for long periods without food or water, which is one reason why they can live for so long.

German Cockroach Lifespan

The German cockroach has a much shorter lifespan than the American cockroach, living for only 100-200 days. This is due to their small size and the fact that they are more susceptible to external factors such as predators, disease, and lack of food and water.

Oriental Cockroach Lifespan

The Oriental cockroach has a lifespan of 4-6 months on average. They are also known as water bugs because they prefer damp areas such as basements and crawl spaces. Oriental cockroaches are less tolerant of dry conditions than other species, which can contribute to their shorter lifespan.

Overall, the lifespan of a cockroach depends on a variety of factors, including species, living conditions, and external factors. While some species can live for up to three years, others may only live for a few months. Understanding the lifespan of different cockroach species can help you identify and control infestations in your home.

Cockroach Life Cycle

Cockroaches are one of the oldest insects on the planet, and their life cycle plays an important role in their ability to survive and populate the earth. All cockroaches go through three stages of life: egg, nymph, and adult.

Egg Stage

The first stage in the life cycle of a cockroach is the egg stage. Female cockroaches lay eggs in a protective casing called an ootheca. Depending on the species, a female can lay eggs multiple times a year and produce hundreds, even thousands of offspring a year. Typically, it will take the eggs one to two months to hatch, but depending on the species, it can happen faster or slower.

Nymph Stage

After hatching, the cockroach enters the nymph stage. Nymphs are small, wingless versions of adult cockroaches. They shed their exoskeleton several times as they grow and develop into adults. The number of molts varies depending on the species, but generally, it takes 10 to 13 molts for a nymph to become an adult. During the nymph stage, cockroaches are vulnerable to predators and environmental factors, such as temperature and humidity.

Adult Stage

The final stage in the life cycle of a cockroach is the adult stage. Adult cockroaches have wings and are capable of reproducing. Females have an estimated adult lifespan of 180 days, while males have an adult lifespan of about 160 days. The lifespan of a cockroach is largely dependent on the species, available resources, and environmental conditions.

In conclusion, understanding the life cycle of a cockroach is crucial to controlling their population. Their ability to frequently reproduce makes them difficult to control, but with proper knowledge and preventative measures, it is possible to keep them at bay.

Cockroach Control and Prevention

Cockroaches are not only unsightly but can also pose a health risk to you and your family. To prevent a cockroach infestation, there are some steps you can take to make your home less attractive to these pests.

How to Prevent Cockroach Infestation

The best way to prevent a cockroach infestation is to deny them access to food, water, and shelter. Here are some tips to prevent cockroaches from entering your home:

How to Get Rid of Cockroaches

If you already have a cockroach infestation, there are several ways to get rid of them:

It’s important to note that cockroaches are resilient and can survive for long periods without food or water. Therefore, it’s crucial to be persistent and consistent in your efforts to eliminate them.

By following these tips, you can prevent and control a cockroach infestation in your home. Remember to keep your home clean and free of clutter to reduce hiding places for these pests.
