What is the Life Cycle of a Flea?

The life cycle of a flea is very complex, but if you have a basic idea of the cycle of a flea, you will be in better shape to know how to combat them in a natural way.  The first stage is called the Definitive Host which is your dog.  The flea has three pairs of legs which aid in the flea's ability to jump from one part of your dog to another part and eats off the blood of your dog.  A female flea lays up to 50 eggs per day on your dog.  The eggs will fall off your dog and on to the carpeting, bedding, soil and floorboards. Next, the Larva stage is where semi-transparent parasites move along eating flea feces.  Pupa is the last stage before the flea adult.  The adult flea can emerge from the cocoon in three to five days or sometimes, it can stay in the cocoon for a year or more.
