German Cockroaches are found in homes, supermarkets, restaurants and other places where there is plenty of food available to eat. They mainly concentrate in kitchens and bathrooms and other humid areas where there is easy access to water as well. Another distinctive trait of the German Cockroach are their droppings. The musty black pepper-like feces they leave behind contain a pheromone that attracts other cockroaches to the area. You may see these around the kitchen, under appliances, around electrical outlets and other dark, secluded areas where there is a lot of warmth.
