Once the flea reaches adulthood, its primary goal is to find blood and then to reproduce. [15] Female fleas can lay 5000 or more eggs over their life, permitting rapid increase in numbers. [16] Generally speaking, an adult flea only lives for 2 or 3 months. Without a host to provide a blood meal, a flea's life can be as short as a few days.
Cat fleas are holometabolous (undergo complete metamorphosis) insects and therefore go through four life cycle stages of egg, larva, pupa, and imago (adult). Adult fleas must feed on blood before they can become capable of reproduction. [10] Flea populations are distributed with about 50% eggs, 35% larvae, 10% pupae, and 5% adults. [11]
Fleas thrive in warm, moist environments. An adult female flea lives an average of 30 to 90 days and can lay 50 eggs each day.
After three larval stages they pupate. Fleas newly emerged from the pupa need to have a blood meal within a week, otherwise they will die. After that they can survive for many months without feeding. The optimum temperature for the flea's life cycle is 70 °F to 85 °F (21 °C to 30 °C). [4]

The human flea (Pulex irritans) – once also called the house flea [1] – is a cosmopolitan flea species that has, in spite of the common name, a wide host spectrum. It is one of six species in the genus Pulex ; the other five are all confined to the Nearctic and Neotropical realms . [ 2 ]
