Bayer K9 Advantix II Flea, Tick & Mosquito Prevention for Medium Dogs

Are you tired of your furry friend suffering from flea bites, tick infestations, and mosquito attacks? Look no further! Bayer K9 Advantix II is here to save the day. This innovative product delivers effective pest protection through topical action, ensuring your medium-sized dog stays happy and healthy.

Why Choose K9 Advantix II?

K9 Advantix II is a comprehensive solution that repels and kills a wide range of pests, including fleas, ticks, mosquitoes, biting flies, and lice. It combines the power of imidacloprid and permethrin with the insect growth regulator pyriproxyfen, which disrupts the hormone signaling of molting insects. This prevents fleas in immature stages from molting, effectively stopping their development.

Key Features:

  • Repels and kills ticks, fleas, and mosquitoes
  • Repels biting flies
  • Kills lice
  • Kills all life stages of fleas
  • Prevents development of fleas, flea eggs, and larvae
  • Kills fleas within 12 hours of initial application
  • Kills reinfesting fleas within 2 hours
  • Protects against ticks that may transmit diseases
  • Waterproof – continues to work after a bath or swimming
  • One application lasts for a month
  • Safe for puppies as young as 7 weeks old

Application Instructions:

Applying K9 Advantix II is a breeze. Simply follow these easy steps:

  1. Open the package and remove the applicator.
  2. Apply the entire contents of the tube evenly to two to three spots on the top of your dog’s back, from the shoulder to the base of the tail.
  3. Massage the solution into the skin to ensure proper absorption.
  4. Dispose of the empty applicator properly.
Length of Effectiveness:

Under normal conditions, K9 Advantix II remains effective for a month. However, in severe flea infestations, retreatment may be necessary earlier than four weeks. Do not retreat more often than once every seven days. Once flea control is achieved, return to a monthly retreatment schedule for continued protection.

  • 8.80% Imidacloprid
  • 44.00% Permethrin
  • 0.44% Pyriproxyfen
  • 46.76% other ingredients

The combination of imidacloprid with permethrin exerts a unique synergistic effect on arthropods, ensuring maximum effectiveness against fleas, ticks, and mosquitoes.

With the new packaging, you’ll receive four one-month applications of Bayer K9 Advantix II for medium dogs weighing 11 to 20 pounds. This means your furry friend will be protected for a whole season!
