German Cockroaches’ Basic Needs
German cockroaches are opportunistic feeders and will eat almost anything, including human food, pet food, garbage, and even other cockroaches. However, there are three essential things that German cockroaches need to survive: food, water, and shelter.
Food
German cockroaches are omnivores and will eat a variety of foods, including:
- Fruits
- Vegetables
- Meat
- Dairy products
- Breads
- Crackers
- Cookies
- Candy
- Grease
- Oil
- Dead insects
German cockroaches are not picky eaters and will eat almost anything that they can find. They are especially attracted to food that is high in sugar, fat, and protein.
Water
German cockroaches need water to survive. They can get water from a variety of sources, including:
- Condensation on pipes or windows
- Water droplets on dishes or in sinks
- Water in toilets or drains
- Leaky faucets
- Pet water bowls
- Standing water
German cockroaches can survive for long periods of time without food, but they will only survive for a few days without water.
Shelter
German cockroaches need shelter to survive. They will hide in a variety of places, including:
- Cracks and crevices in walls and floors
- Behind baseboards
- Under furniture
- In cabinets and drawers
- In the back of appliances
- In the attic and basement
German cockroaches are nocturnal insects and will come out at night to look for food and water. They are attracted to light and will often be found near windows and doors.
How Long Can German Cockroaches Survive Without Food?
German cockroaches can survive for long periods of time without food. In ideal conditions, German cockroaches can survive for up to a month without food. However, in less ideal conditions, German cockroaches can only survive for a few days without food.
Short-term starvation
German cockroaches can survive for short periods of time without food. In a study conducted by the University of California, Berkeley, German cockroaches were able to survive for up to 14 days without food. The cockroaches in the study were kept in a controlled environment and were given water ad libitum.
Long-term starvation
German cockroaches can only survive for long periods of time without food if they have access to water. In a study conducted by the University of Florida, German cockroaches were able to survive for up to 28 days without food as long as they had access to water. The cockroaches in the study were kept in a controlled environment and were given water ad libitum.
German cockroaches are opportunistic feeders and will eat almost anything. They need food, water, and shelter to survive. German cockroaches can survive for long periods of time without food, but they will only survive for a few days without water.
3. How Long Can German Cockroaches Survive Without Water?
German cockroaches are resilient creatures that can survive in a variety of harsh conditions. They can go for long periods of time without food or water, but their survival time will depend on a number of factors.
Short-term dehydration
German cockroaches can survive for up to two weeks without water if they have access to food. During this time, they will slow down their metabolism and conserve water by reducing their activity levels. They will also drink any moisture they can find, such as condensation on the walls or water droplets from a leaky faucet.
Long-term dehydration
If German cockroaches are unable to find food or water, they will eventually die. However, they can survive for up to a month without water if they are in a cool, humid environment. In warmer temperatures, they will only survive for a few days.
Factors Affecting German Cockroaches’ Survival Time
The following factors can affect how long German cockroaches can survive without water:
- Temperature: German cockroaches are cold-blooded creatures, so their metabolism slows down in cooler temperatures. This means that they can survive for longer periods of time without water in cold weather.
- Humidity: German cockroaches need a certain amount of moisture in their environment to survive. If the humidity is too low, they will dehydrate more quickly.
- Age: Younger German cockroaches are more vulnerable to dehydration than older cockroaches. This is because their bodies are not as well-developed and they do not have as much stored energy.
- Other stressors: German cockroaches can also die from dehydration if they are exposed to other stressors, such as heat, starvation, or predators.
German cockroaches are resilient creatures that can survive in a variety of harsh conditions. However, they cannot survive indefinitely without water. If they are unable to find food or water, they will eventually die.
How long can German cockroaches live without food and water?
German cockroaches can survive for up to one month without food and up to two weeks without water. However, their lifespan will be shorter if they are not able to access both food and water.
What are the signs that German cockroaches are in my home?

- Chemical treatments: Chemical treatments can be effective in killing cockroaches, but they can also be harmful to humans and pets. It is important to read the label carefully and follow the directions before using any chemical treatment.
- Biological controls: Biological controls, such as nematodes and predatory mites, can be used to kill cockroaches. These controls are less harmful to humans and pets than chemical treatments, but they may not be as effective.
- Physical removal: Cockroaches can be physically removed from your home by using a vacuum cleaner or by hand. This method is not as effective as chemical or biological controls, but it can be helpful in reducing the number of cockroaches in your home.
- Prevention: The best way to prevent German cockroaches from entering your home is to seal up any cracks or crevices around doors, windows, and other openings. You should also keep your home clean and free of food and water sources.
