American cockroach eggs are laid in dark brown capsules that are about five-sixteenths of an inch long. Female American cockroaches are capable of producing one capsule a week after mating, although they can produce two in one week. Additionally, the female can store sperm, meaning she only needs to mate once to lay multiple egg cases.
Females will lay anywhere from 6 to 14 egg capsules in their lifetime. Each case holds about 16 eggs, and the female can drop the egg capsule within one day of it being formed. After four to eight weeks, nymphs will hatch from the eggs. The overall timing of hatching does depend on environmental factors, such as temperature and humidity.
2. Nymph
After the nymphs hatch from their individual eggs, they join forces and break through the egg capsule using a synchronized effort. From there, it takes them about 6 to 12 months to mature into adults. During maturation, they will molt several times, causing them to change from a light grayish brown to the reddish-brown color you’re familiar with. This stage between a molting period is known as an “instar,” and the number of instars varies in American cockroaches.
3. Adulthood
Once the nymphs have matured, they become adults who mate and lay new egg sacks. On average, the lifespan of the American cockroach from egg to adulthood is 168 to 786 days. Adult females live longer and can survive up to 786 days, while adult males can live up to 362 days.
