What is the incubation period of cockroach eggs?

Cockroaches can go from just a few insects hiding in a home to explosive numbers of them in a short period of time. The breeding period depends on the local conditions, especially how warm it is. The warmer the weather, the quicker they breed. Cockroach eggs can hatch in less than a week in some cases, and a few weeks later they can be laying eggs of their own.
