Fleas have complete metamorphosis with egg, larva, pupa, and adult stages. The adults have piercing-sucking mouthparts and feed exclusively on blood (Figs. 1 and 2). Hosts of fleas are domesticated and wild animals, especially wild rodents. If hosts are available, fleas may feed several times daily, but in the absence of hosts, adults may fast for months, especially at low-to-moderate temperatures. Some species have specialized life cycles, but in general, the life cycle of most fleas ranges from 30 to 75 d.
