Why Pet Armor? PetArmor® will kill adult fleas, ticks and chewing lice as well as the #1
vet-recommended flea and tick line of products. If you and your pets
are not satisfied with PetArmor, we'll refund your purchase.
  • Quickly. Easily. Monthly.
    The active ingredient in PetArmor® is fipronil (the same as in Frontline® Top Spot®). Pet Armor works the same way as Frontline Top Spot, providing full-body protection to help keep your pets flea and tick free, and they stay gone for 30 days. It's that simple. Pet Armor is just as safe and effective as Frontline Top Spot.
  • Our Guarantee
    PetArmor® contains fipronil, the #1 vet-recommended active ingredient used to kill adult fleas and ticks. Because PetArmor uses fipronil, the same veterinarian-quality active ingredient used in the #1 vet-recommended flea and tick product to kill adult fleas, ticks and chewing lice, we guarantee it will kill adult fleas, ticks and chewing lice just as effectively, but at significant savings. If for any reason you're not happy with any PetArmor product, we'll gladly provide you with a refund. Just call one of our experts at
    1-855-ASK-FIDO (M-F, 9AM-8PM ET). Because your pet is our priority.
  • Prevention is the best medicine
    As with most things in life, prevention is much easier and less expensive than treating an existing problem. Even a few fleas can spread throughout your home and be difficult to overcome. Using PetArmor medication every 30 days will protect your pet.
  • What can I expect after treatment?
    After treatment with PetArmor, fleas and ticks get very active as they die and move to the top of the pet's coat where they are more visible. This is a sign that the product is working. If you see fleas several days or weeks after applying PetArmor, you may have an infestation in your yard or elsewhere. Remember to treat all pets in your house with PetArmor every 30 days throughout the year to help protect your pets from fleas and ticks.
  • Treatment checklist
    Fleas don't give up easily. Check off each of these steps as you complete them to help get rid of fleas in your home faster.
  • Use tick and flea protection like PetArmor® on all dogs and cats in your home.
  • Vacuum the entire house, including under furniture, on upholstery and along baseboards.
  • Wash your pets' bedding and anything else they sleep or play on.
  • Re-treat each of your dogs and cats every 30 days.
  • Continue treating monthly, all year long.
