Fiproguard MAX is a topical flea, tick and chewing lice treatment that contains the same veterinarian-recommended active ingredient, fipronil, found in Frontline brand products.
How it works:
Fiproguard Max contains fipronil, which is also the active ingredient in Frontline brand flea and tick preventatives. Fipronil is a broad-spectrum insecticide. It is a slow-acting chemical that disrupts the central nervous system of fleas and ticks. Both Fiproguard Max for dogs and cats contains a second ingredient which maximizes the power of fipronil (cyphenothrin for dogs and etofenprox for cats).
It starts to kill fleas and ticks after one hour of application and will continue to work for a full 30 days, to keep your pets free of fleas, ticks and chewing lice.
