Being the most common species of cockroach, German cockroaches can be found all over the world, though they are believed to have originated in Southeast Asia. These cockroaches prefer to live in cracks in warm, humid places near food and moisture sources, and are highly sensitive to cold temperatures.
German roaches are omnivorous and will feed on almost anything, from meats, starches, sugars, and fatty foods to soap, glue, and toothpaste. They are commonly found in residential and commercial kitchens and bathrooms, along with restaurants, food processing facilities, hotels, and institutional establishments such as nursing homes. They often travel to new locations via grocery bags, drink cartons, and cardboard boxes.
These roaches are a smaller species. Their colors vary from light brown to almost black, and their bodies have two dark, parallel streaks running down their backs. German cockroaches can barely fly, but may glide if disturbed. This species is also one of the fastest reproducing residential roaches, and grows from egg to adult in roughly 50 days.
