Works on Contact

My dog got fleas and I could see them through his fur. Sprayed my dog all over and the fleas would try to run but would suddenly stop. Dead on contact. Stuff works and will definitely order more to keep on hand.

Frequently asked questions

While holding the container upright, spray at a distance of 8 inches to 12 inches from the pet. Spray over the entire haircoat, making sure the coat is thoroughly wetted to the skin. Do not spray directly on the pet’s mouth, nose, eyes or genitalia. For best penetration of spray onto the skin and on heavy-coated animals, direct the spray against the natural lay of the hair, roughing the hair on long-haired dogs or cats. Do this by spraying the ruffled hair directly behind your hand. Make sure the spray thoroughly wets ticks.

This stuff works on all 8 of my outdoor pets.

This works well. Smells good and does not cause any issue with my dogs at all. They are outside 90% of the time, and I have used this spray several other times. It is my go-to for spring and summer fleas and ticks on my Pets. I am now utilizing it with my barn cats as well, since they are difficult to put flea collars onto. I highly recommend this spray and the cost has remained reasonable.

Putting Pests in Their Place

I really like the features of the product. The water-based formula is impressive, non-irritating and easy to use. It's particularly effective as it kills both adult fleas and their eggs, breaking the life cycle. Plus, it works great on both indoor and outdoor pets. A top-notch product for pet owners looking to combat pests!

Effective and Safe for Both Dogs and Cats

I appreciate this product's quick and water-based formula. It safeguards pets for 30 days and is safe for dogs and cats. It eliminates adult fleas and their eggs, offering thorough protection. It's suitable for indoor and outdoor pets, including puppies and kittens. However, I'd prefer a more affordable price, longer protection, natural ingredients, and eco-friendly packaging. Overall, I'm satisfied with the product.

Impressed by the quick and lasting results

This product is really great. It's fast-acting which I appreciate. The easy-to-use spray makes application a breeze. The large 16 oz bottle is a bonus. I also appreciate the water-based formula that protects for 30 days, killing adult fleas and their eggs. I love that it's suitable for both my indoor and outdoor pets, and can be air-dried or blow-dried. The fact that it also prevents the development of adult fleas is a big plus. Highly recommend!

5.0 out of 5 stars I really like PetArmor Fastact Plus Flea and Ti...

This spray is awesome! It's easy to use, kills adult fleas and eggs, and has made a noticeable difference in keeping my pets flea-free. The only thing that could be improved is the scent, which could be a bit better. Also, there is some residue left behind, but it's nothing too bothersome. Overall, I highly recommend PetArmor Fastact Plus Flea and Tick Spray for Dogs and Cats!

So much cheaper than PetSmart! Product definitely delivered. My little dog got fleas and I could see them through his fur. Sprayed my dog all over and the fleas would try to run but would suddenly stop. Dead on contact. Stuff works and will definitely order more to keep on hand.
