Cockroaches, like most insects, go through several instars or life stages. In each case, the roaches look a little different and the process moves very fast.
By understanding the life cycle of cockroaches you are able to quickly take immediate action to prevent them from spreading and multiplying, as well as minimizing the health problems posed by this unhygienic insect.
In this page you are able to understand:
Cockroaches develop by gradual metamorphosis. However, all cockroaches develop by completing a life cycle consisting of three distinct stages:
A female cockroach produces their eggs in an egg capsule known as ootheca. Cockroach ootheca is distinct for each cockroach species, and are often used in species identification. The amount of eggs each ootheca holds depends on the species of cockroach.
Once development inside the egg is complete, the nymphs will work together to break out of the ootheca.
The young cockroaches will go through several more stages, moulting (shedding their skin) and growing larger and larger until they start to look like adult cockroach, yet they are not sexually mature and do not have fully formed wings. If wings are present in that species, cockroach nymphs will develop wing pads in later instars.
Cockroach nymphs will moult several times, and the number of moults required to reach the adult stage will vary. Newly moulted cockroaches will appear white in colour, but will darken within a few hours. The white colour of newly moulted cockroaches often causes people to mistake them for albino cockroaches.
Once the cockroach reaches adulthood, it will have fully-developed wings and antennae. It will also be ready to mate and reproduce.
While cockroaches all complete the same three phases of development, yet the developmental time for a cockroach is strongly influenced by several factors, including:
Additionally, the time it takes for a cockroach to grow from an egg to an adult will vary between cockroach species - ranging from a little over a month to almost 2 years.
At room temperature German cockroaches develop from egg to adult in 40-125 days.
At room temperature, American cockroaches develop from egg to adult in 400-600 days.
At room temperature, American cockroaches develop from egg to adult in 150 days.
In warm, humid places with access to food and moisture, on average cockroach will live about a year. However, there are a few factors that affect cockroach lifespan, including:
