Approximately how long does it take for a German cockroach's life cycle to complete?

The life cycle of a German cockroach typically spans about 2 to 3 months. This cycle consists of three main stages: egg, nymph, and adult. After mating, a female German cockroach produces an egg case that contains multiple eggs, usually around 30 to 40. The eggs hatch into nymphs, which look like miniature adults but are not fully developed. These nymphs undergo a series of molts as they grow, eventually reaching adulthood in about 40 to 60 days, depending on environmental conditions like temperature and availability of food.

This time frame emphasizes the reproductive efficiency of German cockroaches, as they can quickly establish large populations under favorable conditions. The other options, while varying in time frames, do not accurately depict the duration required for a complete life cycle in most environments where German cockroaches thrive. Thus, recognizing the accurate life cycle duration is crucial for effective pest control strategies targeting these common household pests.
