What are dog fleas and cat fleas?

Fleas are parasitic insects which are found all over the world. They feed on the blood of cats, dogs and other animals, including humans.

Fleas in cats and dogs are normally one of two species, either Ctenocephalides felis, the cat flea, or Ctenocephalides canis, the dog flea. However neither is host specific, and while the cat flea can infest dogs and vice versa, both can infest humans.


Fleas are external parasites which affect many animals, causing itching, allergies or even transmitting tapeworms. Whilst the adults are found on pets, the eggs and immature stages of fleas are found in the environment.

What is the Most-Effective Flea Control Method?

Effective flea control requires an integrated approach.

To get effective flea control, the fleas need to be targeted at each and every stage of their life-cycle. The flea life-cycle has 4 components. Adult fleas on the animal lay eggs which then fall into the environment and hatch into larvae. The larvae then develop into pupae, which ultimately emerges as an adult flea. Adult fleas live on the animal and grow by feeding on the animal?s blood. This stage is the stage most people readily see. However, only about 5% of the flea population is in the adult stage. This means that up to 95% of the flea problem lies in the other unseen stages. These stages are not developing on the animal, but rather in the environment in which the animal resides.

Flea Products for Cats - by Method of Application

Flea control for cats requires a strict integrated approach involving treating the affected cat, all in contact animals and the environment. Failure to address all these areas may lead to a failure to achieve adequate flea control for your cat.

Adult fleas are not host specific and therefore live on many different animals. Whilst the adult fleas live on the actual animal feeding on its host's blood, the eggs fall into the environment where they hatch and develop through several stages into adults ready to re-infest any animals in the area. Figures suggest that only 5% of the potential flea population in an area is comprised of adult fleas on the animal with the remaining 95% represented by the immature forms developing in the environment. Hence the need for an integrated approach to flea control.
