Light brown in color, German roaches have two stripes on their backs and the females are darker than the males.
They like the darkness and humidity and, if you find dark droppings in dark areas of your home, that’s a good indication that you might have an infestation of German cockroaches.
The sooner you get your German roach infestation looked at the better, as the females can lay enough eggs to create a swarm in very little time.
