Although flea repellents and mechanical methods of removing fleas are available, the most effective way to achieve flea control is by the use of chemicals that will kill adults, larvae or eggs. There are several products available to kill adult fleas on the host which are safe and effective. These include fipronil, imidacloprid and selemectin, which should be used on a regular basis in accordance with instructions in order to produce ongoing control of adults.

Choice of product may be influenced by route of administration, mechanism of action, duration of effects and efficacy.
There are two main groups of products that act on life stages free living in the environment. Juvenile hormone analogues, such as methoprene and pyriproxifen, disrupt thte normal sequential activation of genes necessary to direct the development of successive stages of the flea life cycle. These products are also ovicidal. Insect development inhibitors, such as lufenuron and cyromazine, interfere with chitin synthesis. Lufenuron prevents the synthesis of chitin to interupt embryogenesis, hatching and moulting, whereas cryomazine stiffens chitin to prevent expansion with flea growth. Use of chemicals these chemicals in combination with those controlling the adult flea population on the host gives complete flea control.
If pruritus is severe, it may be necessary to treat the affected animal symptomatically as well as controlling its fleas. A short course of glucocorticoids, e.g. prednisolone, can be used for this purpose.
