Sevin dust contains the active ingredient carbaryl, which can be used to kill fleas. It is available in both spray and dust forms and can be used outdoors or directly on a pet.
Though there are several insecticides that are available for killing fleas, care must be taken in their application. Wear protective clothing and dispose of unused chemicals properly to prevent problems from accidental exposure.
In addition to insecticides, a cleansing bath followed by brushing can help get rid of fleas on pets. Insect growth regulators can be given to pets to prevent the development of fleas and larvae. The introduction of flea predators into the environment is another method used to kill fleas.
