How long do cockroaches live?

Cockroaches have been on Earth for more than 350 million years. Cockroaches are extremely resistant to hunger and can survive for more than two months without water. Cockroaches can survive for a week without a head, and die of thirst because they have no head to drink water. Cockroaches can survive longer without food than when they are full. Cockroaches can survive for a long time, and it has been found that cockroaches can survive for eight days after their necks were destroyed. Females can lay an egg shell with up to 30 young eggs in it at a time.

With sufficient food and water, the life span of cockroaches varies depending on the species, ranging from 90 days to 365 days. Common local species in Taiwan:

1. American cockroach (Periplaneta americana). Lifespan: 450 days. Found in warm and moist places, such as kitchens, drains, and sewage holes.

2. Australian cockroach (Periplaneta australasiae). Lifespan: 4-6 months. Found in dry places, such as kitchen cabinets and storage rooms.

3. German cockroach (Blattella germanica). Lifespan: 150 days. Commonly found in kitchens.

Cockroaches have a special habit:

When the female is about to die, she will lay eggs in order to leave offspring and prevent the whole family from being destroyed. The life cycle of cockroaches: The survival period of German cockroaches is 6-9 months, while the survival period of American cockroaches can reach 24-30 months. There are about 75 species in Taiwan. Common indoor cockroaches are American cockroaches (the most common large cockroaches), Australian cockroaches, German cockroaches, house cockroaches, etc. Taking the American cockroach as an example, its female can survive for more than a year and can lay five or six hundred eggs in a lifetime. American cockroaches can go without food for three months by consuming nutrients in their bodies; at the same time, they can endure not drinking water for a month. There is a kind of cockroach that can survive after being frozen for 48 hours! Such a tenacious vitality is probably the reason why it can survive on Earth for 400 million years!
