The German Cockroach is a small species of cockroach. Much smaller than the American Cockroach, and often confused with the Asian Cockroach. While there are many similarities, there are some differences. One easy difference is the fact that the German Cockroach doesn’t fly, at least not very far. The Asian Cockroach flies fairly well in comparison and is attracted to light.
The German Cockroach is not likely to survive in places without human activity. Residential infestations are usually worse in kitchens and bathrooms where there are food and moisture sources. Commercial infestations are usually found in restaurants and food processing facilities.
The German Cockroach can contaminate food with their feces and pheromone secretions. They transport pathogens that can cause allergies or other respiratory problems. German cockroaches may transmit bacteria responsible for food poisoning. Cockroaches act as mechanical vector in transmitting Salmonella, Shigella, and Cryptosporidium parvum bacteria that cause diarrheal diseases.
Most people have a very low tolerance for this pest in their home and will go to excessive lengths to eliminate them. This particular pest, unlike the American Cockroach or Brown-banded Roach requires a more extensive program for eradication.
