Did the ingredients in PetArmor® for Dogs or PetArmor® for Cats change?

No, the ingredients in PetArmor for Dogs or Cats did not change. This product still contains the #1 veterinarian-recommended active ingredient, fipronil, at the same amounts.

Is it normal to still see fleas and ticks on my pet a few days after treating it with PetArmor?

Yes. After treatment with fipronil, 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 actually a sign that the product is working. However, if you’re seeing 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.

Can I use PetArmor more than once in a month if my pet has a really bad flea or tick problem?

No. PetArmor should not be used more than once every 30 days. If you have a bad infestation, talk to your veterinarian about your options.

Does your product have an expiration date? What is the shelf life of the product?

This product has a shelf life of three to five years. When properly stored and under ideal conditions it will be five years. If there has been a variance in temperature (extreme heat for example), it may reduce the effectiveness of the product. Be sure to store the product in a cool (below 77°F/25°C) dry place inaccessible to children and pets. Do not refrigerate and protect from direct sunlight.
