Advantix II Flea Control for Dogs Review

Advantix II Flea Control for Dogs Review


Has your flea and tick control stopped working for you lately?

Maybe you’re just looking for a product that offers broad-spectrum protection year round, no matter how much your dog is exposed.

Regardless of why you’re looking for a good flea and tick treatment, we hear at Fix Fleas want to help.

One product that many people use when other products simply don’t do it for them anymore is Advantix II. It has three ingredients that we’re going to review, then we’re going to take a look at real users have to say about it.

By the end of this article, you’ll know enough about this product to make an informed decision regarding your next flea control product.

Company Claims

According to Bayer, the manufacturers of Advantix II, the product kills and repels the following:

  • Fleas
  • Ticks
  • Lice
  • Mosquitoes
  • Biting flies
  • Flea eggs
  • Larvae

Since these pests can cause serious illnesses including Lyme disease, ehrlichiosis, allergic dermatitis, West Nile disease, and a myriad of other problems, keeping them off of your dog is paramount to your pet’s health. They can make you sick, too, so it’s not just your dog that you’re protecting.

It’s waterproof, lasts 30 days and easy to apply.

Active Ingredients

  • Imidacloprid 8.8%
  • Permethrin 44%
  • Pyriproxyfen 0.44%

How it Works

Imidacloprid acts as a neurotoxin that blocks neural pathways in the pest’s brain, thus causing seizures, paralysis, then death. Permethrin, a synthetic neurotoxin, acts similarly and pyriproxyfin is an insect growth inhibitor that prevents eggs and larvae from growing, maturing, and being able to bite or reproduce.

What Are Users Saying?

There are only a few stray bad reviews for this product, though for other permethrin products, the lists are generally huge with people reporting negative side effects. The vast majority of people absolutely love this product and even report that once Frontline stops working, Advantix II is the go-to product that works for them. In a nutshell, this product seems to be safe and effective on most dogs.

Usage Information

Directions for Advantix is a bit different that for other products; instead of simply applying the entire tube to the area between the shoulder blades, instructions say to use a few dots that go from between the shoulder blades down the spine to the base of the tail.

Product Warnings and Side Effects

As suspected, the warning list is long. Don’t use on puppies under 7 weeks old and wash your hands after using. It’s toxic to cats, fish and aquatic animals, and possibly even to small dogs so if you have any of those animals, you should either avoid using Advantix II or use it with extreme care.

Irritation may occur at application sites. If they don’t go away or if they get worse, contact your vet.


Usually we don’t recommend products that contain permethrin but because this has so many positive user reviews with so few negative responses, we’re going to tentatively recommend it so long as you have a healthy dog.

If you have a cat, use with extreme caution and make sure that you keep your animals separate for at least 24 hours so that the product has time to dry.

    I have 2 dogs that I use K9advantix11 on….Before treatment I could see hundreds of fleas crawling on them everywhere…After treatment within 36 hours not 1 flea could be found…great product!

    I accidentally switched the Advantix II a couple of years ago when I bought what I thought was Advantix (which I had been using for several years and was very happy with) from my vet. At that time, I did not realize that there was a new formula. I needed both flea and tick protection, as my dog is involved in a lot of outdoor activities, so decided to try the new product. What a disappointment!! Over the course of that summer, my Golden Retriever picked up fleas on three different occasions – and he had never had fleas while on Advantix. I ended up applying the Advantix II at three week intervals (I had been able to get away with 4-6 week intervals with Advantix), before I was able to get rid of the fleas on him. When I called the manufacturer to complain about the product, all they did was ask exactly how many fleas I had found on the dog. I wasn’t counting them – one flea was too many, as far as I was concerned. I will never use Advantix II again!
