The proven ingredients of Advantix II kill and repel more parasites than Frontline Plus for dogs (based on label claims) - including mosquitoes, which can carry heartworm disease.

Imidacloprid and permethrin repel and kill ticks, fleas, and mosquitoes. These ingredients also repel biting flies and kill lice on dogs. K9 Advantix II kills and repels ticks, often before they can attach. If ticks are repelled or killed, they can't attach and transmit organisms that may cause disease, such as Lyme disease.

Advantix II also contains the IGR (Insect Growth Regulator) pyriproxyfen. In addition to its signature 5-way, repel-and-kill pest protection system, Advantix II also kills immature forms of fleas (eggs, larvae, and pupa) to keep them from developing into biting adults. Advantix II kills existing fleas within 12 hours and reinfesting fleas within 2 HOURS! It actively breaks the flea life cycle.

For dogs and puppies only: 7 weeks or older. Do not use on cats.

What makes Advantix II Special?
Synergistic Effect
The two active ingredients imidacloprid and permethrin are often used alone as effective treatments against parasites. However, the combination Advantix formula works synergistically to provide more protection than each of these ingredients alone. Together, they complement one another to enhance their effectiveness and provide complete protection against fleas, ticks, and mosquitoes.

The active ingredient imidacloprid is an EPA approved topical insecticide that kills adult fleas by disrupting their nervous system. Fleas in their larval stages are also killed when they come in contact with the treated pet or their immediate surroundings. Permethrin is a synthetic pyrethrin compound commonly used to kill flying insects, fleas, and ticks. EPA approved for use in dogs, permethrin affects the nervous system of parasites, causing repetitive nerve firings that eventually paralyze and kill them. Permethrin is longer lasting and more stable than natural pyrethrin. For this reason, it is commonly found in repellents, premise sprays, and in products intended for slower, but sustained action. K9 Advantix II takes advantage of these properties to offer superior protection against fleas, ticks, and mosquitoes.

Protection Against Fleas
K9 Advantix II stops fleas from biting in less than 5 minutes and kills 98-100% of fleas on your dog within 12 hours of application. K9 Advantix II kills fleas before they have a chance to lay eggs and also kills flea larva before they develop into biting fleas - thus breaking the flea life cycle. Re-infesting fleas are killed within 2 hours for reliable treatment against fleas of all stages. In many instances Advantix II is so effective it kills fleas before they have a chance to bite your pet, preventing conditions such as Flea Allergy Dermatitis.

Protection Against Ticks
K9 Advantix II repels and kills Deer Ticks, American Dog Ticks, Lone Star Ticks, and Brown Dog Ticks before they can latch onto your pet. It repels up to 98% of ticks to dramatically reduce disease spread by ticks.

Protection Against Mosquitoes
K9 Advantix II repels and kills mosquitoes before they can bite and needless to say, mosquitoes that don't bite can't annoy dogs or transmit disease. Research demonstrates K9 Advantix II kills up to 98.3% of mosquitoes and reduces their feeding up to 95.2%.

Waterproof Formula
K9 Advantix II remains effective after swimming or bathing (use a non-detergent-based shampoo). Even after repeated swims, or bathing it remains an effective treatment.

Easy Application
K9 Advantix II is a monthly topical treatment that is easily applied between your pet's shoulder blades. One application, applied along the back in two to six spots (depending on size of dog), will stop fleas from biting in 3 to 5 minutes and is gentle enough for puppies (7 weeks or older) and dogs of all sizes. (See package directions.)
