This is when the flea spins a white, silken cocoon for itself. The flea stays in this stage from one week to six months changing in a process called metamorphosis. When the flea emerges, it begins the final cycle, called the adult stage. A flea can now suck blood from host and mate with other fleas. A single female flea can mate once and lay eggs every day with up to fifty eggs per day.
Fleas like to live in an environment that is warm, where they can live up to a year.
