Overview on Cat Fleas

If you have a cat at home, most likely, you have experienced dealing with flea problems. This is especially prevalent in the US. Cat flea, with the scientific name Ctenophalides felis, is one of the world’s most prominent fleas.

The Life Cycle of a Cat Flea

There are 4 stages in every flea’s life which are: egg, larva, pupa, and adult stage. Let us discuss each one briefly.

1. Egg- The size of the egg is usually 0.5mm, white in color, and is shaped like an oval. The female fleas lay eggs on the host, or in well-hidden areas like the lawn, carpet, or bed sheets. Eggs hatch after two days.
2. Larva- Once the egg hatches, it forms into a larva. In this stage, it has no eyes and legs yet, just hair covering the entire body. They survive by eating “flea dirt” (undigested blood) and other organic debris found on the host or in the environment.
3. Pupa- This phase involves 4 stages of metamorphosis, and thereafter, it forms a cocoon. As to when it becomes an adult flea is not really clear because factors affect the progression such as: temperature, humidity, and carbon dioxide supply. It can take as short as 3 days to as long as a year. The cocoon is made up of sticky exterior which accumulates debris and dirt that they can feed on, and also serves as camouflage for the pupa.
4. Adult- Once the flea has emerged from the previous stage, it becomes an adult. An adult flea has 3 pairs of legs, with hair-like bristles around its body. Fleas jump with the help of their hind legs.
