The Australian cockroach grows from a nymph to an adult in about a year. While it looks similar to an American cockroach, the adult roach is significantly smaller. The body length is between 23 and 35 mm. The adult cockroach is dark red or brown, with a yellow stripe down its back. It lays its eggs in moist areas, such as kitchens. It can lay as many as 16 eggs per clutch. The eggs are about a quarter of an inch long, and have a small number of nymphs inside.
The life cycle of an Australian cockroach includes eggs, five nymphal instars, and the adult stage. In total, an adult Australian cockroach lays 20-30 eggs during its lifetime. Females lay an egg every 10 days, and it takes between 30 and 40 days for the egg to hatch. After hatching, the nymphs spend six to 12 months in this stage before reaching adulthood.
The Australian cockroach is a species of insect found worldwide. Adults are larger than the juveniles, and they range from 1.25 to 1.4 inches long. Both sexes have a pronotum and two pairs of legs. The cockroaches are nocturnal, and are good runners.
The Australian cockroach likes warm, humid environments. They are not very cold-tolerant, but they will move indoors when the weather becomes too cold. They also prefer warm places that have lots of moisture and plenty of food. In particular, they enjoy moist places like sinks, bathtubs, cabinets, and drains. They can also invade homes and large structures because they are attracted to areas with high humidity and food sources.
