Frontline is recommended by more veterinarians for flea and tick control for dogs and cats than any other brand.  Frontline Plus offers long-lasting and the most complete flea and tick control available by quickly killing 100% of the fleas and ticks on your pet within 48 hours or less.

In addition to the same strong coverage offered by Frontline Top Spot, Frontline Plus also kills flea eggs and larvae. Frontline Plus completely breaks the flea life cycle by effectively stopping the development of new fleas and it kills all stages of 4 major ticks including the one which may carry Lyme disease.  The benefits of Frontline Plus include: 

Frontline kills 98 to 100% of existing fleas in less than 24 hours and continues to provide fast-acting, long-lasting flea and tick control for 30 days or more.  The active ingredient in Frontline products is Fipronil, which is stored under your pet's skin, in the oil glands.  As a result, Frontline is continuously reapplied  to the skin and hair through the hair follicles making it waterproof.  Fipronil is a phenylpyrazole antiparasitic agent.  Fipronil's mechanism of action in invertebrates is to interfere with the passage of chloride ions in GABA regulated chloride channels, which effectively disrupts CNS activity.

Frontline Plus also contains the active ingredient Methoprene which is an insect growth regulator (IGR).  Methoprene works on certain pests in their immature (egg and larvae) stages, which breaks the cycle of infestations and prevents re-infestations.  Immature pests exposed to Methoprene do not reach adulthood and cannot reproduce.

To apply, simply squeeze Frontline Plus or Top Spot between your pet's shoulders and the active ingredient, fipronil, will quickly dissolve into the natural oils of the skin and coat.  It rapidly spreads over your pet's entire body to provide long-lasting, waterproof flea and tick control that keeps working for a full 30 days.
