About German Cockroach
The German cockroach (Blattella germanica) is the most economically significant cockroach species on Earth, found on every inhabited continent. Measuring 13–16 mm with two dark stripes on the pronotum, it thrives in warm, humid kitchens and bathrooms, hiding inside appliances, beneath sinks, and within wall voids during the day. A single female can produce up to 40,000 offspring per year, and populations develop pesticide resistance rapidly. Beyond contaminating food, its shed skins and feces are potent allergens linked to asthma in children and it carries over 30 pathogenic bacterial species.
Geographic Distribution
