Advantage II is a monthly topical flea control for dogs that kills fleas through contact, so fleas do not have to bite to die. Advantage II kills fleas rapidly within 12 hours of initial application. Reinfesting fleas are killed within 2 hours, with protection against further flea infestation lasting for up to a month. Advantage II provides the additional benefit of killing flea eggs and larvae to effectively break the flea life cycle, while also treating, preventing and controlling lice infestations.

This fragrance-free topical is waterproof after 24 hours and is for use on dogs and puppies 7 weeks of age and older, weighing 3 lbs. or more.

One treatment of Advantage II is effective for 1 month. In cases of severe flea infestation, re-treatment may be necessary earlier than 4 weeks; clients should not re-treat more often than every 7 days. After flea control is attained, your patient can return to a monthly treatment schedule.


9.10% imidacloprid

0.46% pyriproxyfen

Imidacloprid attacks fleas’ nervous systems — paralyzing and ultimately killing them.

An insect growth regulator (IGR), such as pyriproxyfen, inhibits the development of flea eggs by mimicking the juvenile growth hormone. This ingredient prevents immature flea stages from molting into the next stage of the life cycle and keeps them from developing into adult fleas. It also offers additional larvicidal properties when compared with imidacloprid alone.
