The German cockroach is the most prolific breeder out of all the species of cockroaches, taking as little as 40 days to develop from hatching to adulthood. Given how quickly a German cockroach takes to become fully reproductive, and the fact a that a female carries 30 – 40 eggs in each egg casing and generates up to 4 egg casings per year, it’s of no surprise how quickly this species of cockroach can take over a commercial or domestic premise.
The majority of infestations are associated with kitchens and other food handling areas due to German cockroaches preference for conditions that provides food, warmth and moisture. These areas provide harbourage areas such as cracks and crevices in which German cockroaches can hide during the day. The German cockroach is usually found under sinks and cupboards, in and under drawers, in and around water heaters and appliances such as refrigerators, stoves, microwaves, and in wall voids adjoining kitchens and bathrooms. This cockroach seeks conditions that provide warmth, moisture and food.
