Getting rid of cockroaches can be a real headache, and it's something everyone wants to address as quickly as possible. Depending on the severity of the cockroach problem and the methods used, it can take anywhere from a few days to several weeks to completely eradicate an infestation.

Do roaches make an apartment uninhabitable? Roaches can make an apartment uninhabitable if the infestation is severe enough. In California, landlords are required by law to provide tenants with habitable living conditions, which includes freedom from vermin and pests such as cockroaches.
The lifespan of a cockroach is usually one year, and in any female roach's lifetime, she can produce anywhere between 200 to 300 offspring or 6 generations a year. The number of eggs a single cockroach can produce will vary from species to species.
