The combination of the two active ingredients Fipronil and S-methoprene, targets all the stages within the flea life cycle including pupae, egg and flea stage making it a highly effective treatment. After the spot-on application is administered, the ingredients spread over the surface of your cats’ fur and sebaceous glands killing fleas within 24 hours and ticks within 48 hours. The fleas do not need to bite your cat to be destroyed.
Fipronil is the ingredient that affects adult fleas and ticks. It works by affecting the central nervous system of the flea, creating irregular movements prior to death. At this stage fleas may become more visible, losing their instinct to hide and appearing to ‘dance’.
S-Methoprene works by inhibiting the development of immature insects, mimicking juvenile hormones and causing impaired development and death of the immature flea. It also prevents the contamination of the treated pet’s environment.
With these two active ingredients, Frontline Plus is one of the leading cat flea treatments on the market. Regular monthly flea treatment application ensures that your cat and home remain free of fleas.
