German cockroaches are highly adaptable and can survive in a wide range of environments. They are commonly found in kitchens and bathrooms, as they are attracted to warm, humid environments with access to food and water. They are also capable of reproducing quickly and producing large populations, which makes them difficult to control if they become established in a home or building.
German cockroaches are primarily nocturnal, active at night and hiding during the day. They are known to be very fast and agile and can easily hide in small spaces, such as cracks and crevices. German cockroaches are also known to be able to climb smooth surfaces and can often be found near ceilings and on walls. They are scavengers and will eat almost anything, including food scraps, toothpaste, soap, and even book bindings.
German cockroaches can spread germs and bacteria and trigger allergies and asthma symptoms. They can also cause damage to buildings and personal belongings, such as gnawing on books, paper and other materials. Their droppings and shed skins can also trigger allergic reactions in some people.
