Advantage II Flea Control for Cats & Dogs

What is Advantage II?

Advantage II is a monthly flea preventative for dogs and cats that offers comprehensive flea protection by killing adult fleas, larvae, and eggs. Plus, it kills fleas through contact, which means fleas don't have to bite your pet to die. Advantage II also treats, prevents, and controls lice on dogs. Advantage II does not kill ticks, so we recommend using the Preventic Tick Collar along with Advantage II (dogs only).

For:

Dogs (3 lbs or over and 7 weeks of age or older), Cats (2 lbs or over and 8 weeks of age or older)

Benefits:

Kills fleas within 12 hours of application
Kills all flea life stages including flea eggs and larvae to prevent infestation
Treats, prevents, and controls lice infestations (dogs only)
Safe and easy to apply
Waterproof remains effective even if pet gets wet

How it Works:

The first active ingredient is imidacloprid, which acts on the nervous system of the flea to cause paralysis and subsequent death. Within 12 hours of application, 98-100 percent of fleas are dead. The second active ingredient, pyriproxyfen, is an insect growth regulator. Once a female flea lays her eggs, pyriproxyfen works to prevent the eggs from hatching, ending the flea life cycle. Also, the active ingredient in Advantage II kills through contact, which means that fleas don't have to bite your pet to die.

Cautions:

Individual sensitivities, while rare, may occur after using any pesticide product for pets. If signs persist, or become severe, consult a veterinarian immediately. Do not get this product in your pet's eyes or mouth.

Directions:

Apply Advantage II once a month every month.
For dogs up to 20 lbs, part the pet's hair between the shoulder blades until you can see the skin. Place the tip of the applicator on the skin and release all of the tube's contents on a single spot directly on the skin.
For dogs 21 lbs and over, apply entire contents of the tube evenly in 3 or 4 spots on the top of the back from the shoulder to the base of the tail. At each spot, part the hair until the skin is visible. Place the tip of the applicator on the skin and release a portion of the Advantage II solution directly on the skin. Do not apply an excessive amount of solution at any one spot that could cause some of the solution to run off the side of the dog.
For kittens and cats, place the applicator tip through the cat's hair to the skin on the neck at the base of the skull and release all of the tube's contents on a single spot directly on the skin.
Use only one applicator per treatment.

Tip:

Under normal conditions Advantage II is effective for a month. However, in case of severe flea infestation, retreatment may be necessary earlier than four weeks. Do not re-treat more often than once every seven days. After flea control is obtained, return to a monthly treatment.

Rated 4 out of 5 by Anonymous from Awesome product Have had more success with advantage II from 1800 pet meds than with Frontline bought from farm supply in my local county

Rated 5 out of 5 by kammy2345 from The only medicine that kills fleas fast I have tried many other flea medicines before and none of them help. We have multiple cats and unfortunately got an infestation of fleas last summer. I couldn't walk into my bedroom without having 5 or 6 jump onto my legs. Not to mention my cat was terrified of jumping on the floor because they swarmed her. I tried bug bombs, and frontline plus, flea collars, and nothing worked. Until i got advantage and it killed nearly all of them within a week and stopped the infestation. I still had to vacuum and sanitize everything but it works great and you see results fast. Frontline didn't even keep the fleas off of my cat. It only killed the ones that were on her the day i treated her. The next day they were still biting her. Also 1800petmeds is the best place to buy this product otherwise it gets really expensive other places.

Rated 5 out of 5 by cat lady from It works! I like this product for my cats because it works better than the popular, leading brand. It seems to be stronger and work longer.

Rated 5 out of 5 by Suzanne from Good stuff Advantage II does what it's supposed to do.....which is it takes care of fleas. About a year ago the scent was reformulated and it now doesn't smell as strong as it used to.

Rated 5 out of 5 by winston from Excellent Price! I shopped around at some local and very popular pet supply stores before buying from 1800Petmeds. The prices at the other stores was $25 dollars more than 1800petmeds, I don't know about you but I certainly don't want to pay more for any thing. I highly recommend this site and will be placing another order in the very near future.

Rated 5 out of 5 by Ramona from Exceptional results! I have indoor-only cats. Somehow, in my apartment, we keep getting fleas anyway. I tried Frontline because it is a known product, but my largest cat had a skin reaction to it. This time around, I tried Advantage II. My big boy FINALLY stopped biting his front legs, can allow me to pet him without feeling those biting critters, and has had no skin reaction whatsoever. I bought several so I can treat all the cats again the next few months, washed everything I could, and treated the carpets with Precor Plus. So far, it's been 2 weeks and no sign of flea dirt or excessive scratching. I love this stuff!

Rated 4 out of 5 by Hec918 from On second dose and still seeing some fleas Not sure why I'm still seeing some fleas after 2 month of use. They are mostly all gone but I just saw one on him. I figured the cycle would be finished after 2 months. I'm going to continue to use it hoping it will finally break the cycle after another month. I did see one 2 weeks ago but it was half dead and easy to get and flush. The one tonight was fast and got away.Product has great reviews.

Rated 5 out of 5 by Marty from Advantage II surely has an advantage against those I have ordered this several times over the years. Simply, it works, killing fleas, eggs, larvae. It is just the ticket for your loved ones, because they are not like family, they are family. They don't ask for much. I wish I could save them all, but I can't, so I do what I CAN.
