The German cockroach (Blattella germanica) is one of the most abundant species of cockroaches found in homes and businesse across the United States. These unpleasant little creatures reproduce rapidly and their favorite place to reside is among human beings with easy access to a rich diet of human food. Adult cockroaches are easy to recognize with their light brown coloring and two black horizontal bands behind the head. They are one of the smallest species of cockroaches measuring roughly half an inch in length. Young cockroaches called nymphs are darker in color and much smaller in size. Although the adults have wings they rarely use them, instead they prefer to run from danger seeking refuge in tiny cracks and crevices.
German Cockroach Identification
Although the German cockroach is more than capable of living outside, they are most often found inside in warm and humid areas such as bathrooms and kitchens. More often than not unsuspecting home and business owners introduce cockroaches onto their property inside bags and other containers that are carried into the home. Well known for their scavenging abilities, German cockroaches feed on a variety of food sources including soap and the glue from book and magazine bindings but they will also scavenge for even the tiniest scrap of food in the form of forgotten crumbs or a discarded plate accidentally left on the kitchen counter. German cockroaches reproduce quickly; surprisingly the females need only mate once to produce young. After mating the female will produce approximately 4 to 6 egg cases during her lifespan, with each case containing approximately 30 to 40 eggs. The average timespan from egg to maturity is approximately 100 days with the adult cockroach surviving an additional 100 to 200 days.
Signs of a German Cockroach Infestation
One of the most obvious signs of a German cockroach infestation is in the form of droppings which resemble small dark specks similar in appearance to ground pepper. You may also notice fecal matter in the form of dark spots which will typically be found near small cracks and crevices around walls and windows. Other indications of cockroach activity include the evidence of empty egg cases. In some instances, especially when cockroaches are present in large numbers you may smell a mild musty smelling odor.
German VS Asian Cockroach
Although the German and Asian cockroaches are similar in appearance their patterns of behavior are distinctly different, for example German cockroaches are best known for their preference for indoor environments, while the Asian cockroach is most often found outdoors. More importantly, the Asian cockroach is renowned for its ability to fly, while the German cockroach on the other hand prefers to run and hide from any perceived threat.
Diseases, Health Problems & Dangers of German Cockroaches
The German cockroach is responsible for the transmission of pathogens including E.coli and Salmonella. In heavily populated urban areas, the increased occurrence of asthma in children is also attributed to the presence of large numbers of cockroaches.
