Fleas 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. Flea populations are distributed with about 50% eggs, 35% larvae, 10% pupae, and 5% adults.
What are fleas? Fleas are small insects about 1-2 mm in length. Adult fleas live in the coat and bedding of dogs, cats and other animals and feed on their blood. The female adult lays eggs (up to 500 per flea per day!) which roll off the animal into the environment, and then hatch into larvae.
