How to get rid of this?.To get this pest problem under control, inspection is the first and foremost step.
German cockroach droppings may appear as small, dark, “pepper-like” material left on countertops or in drawers. Fecal staining may appear as dark spots or smears, some that are slightly raised, in the corners of rooms, along the tops of doors or around small cracks and openings in walls.
German cockroaches produce a large number of nymphs in each ootheca. Their small size allows them to hide more efficiently, and they have few natural predators in human habitats. For these reasons, German cockroach populations tend to grow rapidly and require professional treatment. Contact your local pest control expert for a consultation.
Although capable of living outdoors in tropical environments, German cockroaches are most commonly found indoors, with a preference for the warmer and more humid areas of a structure. In homes, these insects will typically be found in kitchens and bathrooms, but can move to other areas of a home if food and moisture are available.
German cockroaches are scavengers, capable of feeding on most any food source available, including toothpaste, soap and the bindings of books. These pests are known for their ability to capitalize on the availability of even the smallest amounts of food by feeding on crumbs missed during cleaning or feeding on the dirty dishes left in the sink overnight.
