Advantage™ Ⅱ flea control is a spot-on topical application which is applied to your pet on a monthly basis. Imidacloprid paralyzes fleas within 3-5 minutes of contact, helping to prevent the bites that cause itching, scratching, skin odors, and allergic reactions. Pyriproxyfen disrupts the maturing process so that flea eggs and larvae cannot mature into biting fleas.
Fleas on your pet die within 12 hours. They stop biting within 3-5 minutes of contact. And pyriproxyfen kills re-infesting fleas within 2 hours.
