If you have German cockroaches, one of the first things you should do is remove them from your home. German cockroaches are common in kitchens and bathrooms, where they thrive in moist and warm environments. They can also invade bedrooms and other areas where food is commonly stored. German cockroaches can fit through small openings, so you should be prepared to eliminate them as soon as you see them.
The German cockroach is found worldwide. These pests are common in homes, hotels, and nursing homes. While their range includes many parts of the United States and Europe, they have also been recorded in sub-Saharan Africa and Madagascar. They are endemic in many parts of the world, and are one of the hardest pests to control.
German cockroaches lay eggs in a case called an ootheca. Each ootheca can contain up to eight eggs. The eggs hatch in between 16 and 24 days. The German cockroach lays approximately four to eight oothecae in its lifetime. The oothecae are leathery and shaped like a bean. The female German cockroach carries the protective capsule until it is close to hatching time, and then deposits it at a hidden location where it will hatch. After hatching, the egg cases split open, and the nymphs emerge.
The size of a German roach depends on their environment. If you have children, they may leave food crumbs and this can attract them to your home. They also like light, so if you have light or food sources around, they may be attracted to them as well.
