How to get rid of this?.To get rid of pest problem under control, inspection is the first and foremost step.
Adults are easily recognized by their light brown or tan coloration with two black horizontal stripes located on the pronotum immediately behind the head. The young, or nymphs, are darker, almost black in color, also with the black stripes behind the head.
While adult German cockroaches have wings, they rarely fly, preferring to run.
German cockroaches spread filth in homes, contaminating food and utensils. Pathogens range from bacteria that causes food poisoning and dysentery to allergens that result in rashes and asthma attacks. Recent studies have also indicated that in larger metropolitan areas, the development of asthma in children can be directly linked to the presence of the pest.
As adults, German cockroaches can survive anywhere from 100 to 200 days.
These cockroaches lay 40 eggs at a time, which mature in about two months. Because they reproduce rapidly, infestations quickly become severe. German cockroaches are hardy and fast and have few natural predators inside human habitats. For these reasons, their populations tend to grow rapidly and can be hard to get rid of, often requiring professional treatment.
May appear as small, dark, “pepper-like” material left on countertops or in drawers. Fecal staining may appear as dark spots or smears:
Along the tops of doors, around small cracks and openings into walls, and in the corners of a room.
Since German cockroach females carries their egg case until 1 to 2 days before depositing it, empty egg cases may be found in areas that the females frequent.
German cockroaches are also known to secrete a number of odorous compounds. When populations are present in large numbers, it may be possible to detect a mild, or what some have reported as a “musty” odor.
