German Cockroaches

Adult German cockroaches can be identified by their light brown to tan coloration, featuring two dark almost parallel stripes on their backs. Female German cockroaches tend to have a darker appearance compared to males. The nymphs of German cockroaches are dark brown to black in color and also exhibit the same dark stripes on their backs. Despite having wings, German cockroaches rarely fly and instead prefer to run.


German cockroaches are more likely to live in warm and humid areas near sources of food and moisture. Infestations of these pests are commonly found in kitchens, both in residential and commercial settings, as well as in bathrooms. Droppings from German cockroaches can often be found in the areas they frequent.


Droppings look like small, dark pepper and can be seen on different surfaces like countertops or inside storage compartments. You might also find evidence of fecal staining, indicated by dark spots or streaks in the corners of rooms, along the top edges of doors, or near hidden cracks and entry points.

When there are many German cockroaches, you might notice a slight, somewhat musty smell.


German Cockroach Prevention

Wondering how to eliminate German cockroaches? The most effective method for controlling German cockroaches is to maintain good sanitation. To prevent these roaches from infesting your home or place of business, make sure to keep your kitchen clean by regularly wiping up crumbs, cleaning spills, and vacuuming. Additionally, avoid allowing dishes to pile up in the sink.
Another crucial step is to seal any openings in the building, particularly around utility pipes, and ensure proper ventilation in crawl spaces to prevent moisture accumulation.
