Fleas are all-too-common visitors to both cats and dogs. Contrary to many myths, they are equally at home in a clean house as a dirty one so you needn't be embarrassed to ask for help with controlling them.
 
Beaphar FIPROtec® Spot-On contains fipronil. This is an adulticide, meaning it kills the adult parasite. Fipronil works by killing parasites through contact, not via the bloodstream. This means a flea or tick does not have to bite your pet in order to killed. 
 
How does Fipronil work?
Fipronil works by affecting the nervous system of parasites, which causes hyperactivity before killing them. This is one of the reasons you may appear to see ‘more fleas’ on your pet after treating them with a fipronil product. The fleas become more active prior to death, and often move to the top of coat, becoming more visible. Fipronil has a tendancy to concentrate in the sebaceous glands (the oil-producing glands at the base of each hair follicle), from where it constantly replenishes the skin’s surface. The sebaceous glands act as a store, allowing the treatment to stay effective for longer.
