Advantage II is a fast topical flea control for dogs that kills all life stages of fleas. Fleas are killed within 12 hours. The first active ingredient is imidacloprid, which acts on the nervous system of the flea to cause paralysis and subsequent death. To protect against further infestations, reinfesting fleas are killed within 2 hours. The second active ingredient, pyriproxyfen, is an insect growth regulator. Once a female flea lays her eggs, pyriproxyfen works to prevent the eggs from hatching, ending the flea life cycle. Advantage II kills fleas through contact, so they do not have to bite to die. One convenient waterproof application of Advantage II lasts up to 1 month. For use on dogs and puppies 7 weeks and older. Package includes 4 tubes with 1.0ml each. Do not contaminate water, food or feed by storage or disposal. Store in a cool, dry place. USE ONLY ON DOGS.
