Advantage is a monthly, nonprescription topical flea preventative for pets. In 2013, the original Advantage was replaced by Advantage II, providing extra protection against fleas in the larval stage. There are different doses of Advantage II depending on the weight of the animal. The dog formula is effective against fleas and lice but not ticks. The cat formula is effective against fleas.
Other options for pest control include Frontline Plus and K9 Advantix II.
