German Roaches thrive in warm, humid environments. Parts of the home such as kitchens and bathrooms provide ideal locations for the roaches. The German roach is a scavenger, and can consume even the smallest amounts of food. They are also known to consume certain atypical food sources, such as the binding of books and toothpaste.

The German roach is infamous for its ability to rapidly reproduce. It is not uncommon for extensive infestations to be found hidden in homes. The German roach is most commonly brought into homes in boxes, bags, or any other container they can hide within.

Shortly after being introduced into a space, the German roach will often seek out a hidden area in which to spend time during the day, coming out at night to seek food. The females will create egg capsules or ootheca, that can produce up to 50 roaches. The females will often carry these egg capsules around until they are ready to hatch, making it difficult to destroy the population inside of the home.

There are many easy to identify signs of a roach infestation. The German roaches will often produce droppings that are dark in color. These will either be small and beadlike or just dark stains found around small cracks, wall openings, or the corners of rooms. Another sign is an unpleasant, musty odor that is produced by the roaches. This is caused by certain chemicals excreted by the roaches and will be strongest near to their population center.

German roaches are difficult to remove. Their infestations are often massive, with a population that is rapidly reproducing and remains well hidden throughout the day. Because of the difficulty in identifying and treating the German roach, it is best to consult a pest control professional.
