How long does it generally take for cockroaches to complete their life cycle?

The life cycle of cockroaches typically spans multiple stages: egg, nymph, and adult. In general, it takes about 2 to 3 months for a cockroach to develop from an egg into an adult, depending on environmental conditions such as temperature and availability of food.

During the egg stage, a female cockroach can lay numerous eggs within a case called an ootheca, and the eggs generally hatch after a few weeks. Once the nymphs emerge, they will undergo several molting cycles before reaching maturity, which can take several weeks. Summarizing the entire developmental process, the commonly accepted timeframe for completion of the life cycle from egg to adult is around 2 to 3 months, making this choice the most accurate among the options provided.
