Important Information

Fleas rise to the top of your pet's coat as they die, so consider it a triumph if you start seeing more fleas at first, after treating your pet. If you’re still seeing fleas after application, it may be because your pet has picked up new fleas from the environment, which may include other pets, surfaces and outdoor areas. It may take up to 90 days to break the entire flea life cycle. Additionally, you should also treat sources of new fleas (i.e., carpet, yard, etc.) to ensure complete flea control.

Questions & Answers

Is there an expiration date on these treatment packs?
Answer by ChewyAug 29, 2018
This product does not have an expiration date. As long as you keep it at room temperature and sealed in its original packaging, it will remain ready for use.

Will this kill ticks that are already on my cat?
Answer by ChewyApr 18, 2019
Once applied, FRONTLINE Plus kills ticks for at least one month. A once monthly application is recommended where tick control is needed. Kills all life stages of ticks (larva, nymph and adult).

How often should I give my kitten to use this product?
Answer by ChewyOct 14, 2019
One treatment will last 30 days. This treatment should only be used on cats and kittens 8 weeks or older and over 1.5 pounds.

the Frontline Gold has a 3rd ingredient that kills the eggs, (pyriproxyfen) but Frontline plus also kills eggs?? so what makes this specific ingredient (pyriproxyfen)better if both products kill the eggs?
Answer by ChewyDec 02, 2020
While Frontline Plus and Frontline Gold treat adult fleas in the exact same way, the addition of pyriproxyfen allows Frontline Gold to kill flea eggs and larvae more effectively than Frontline Plus. Frontline Plus can begin killing these pests 4 hours after application, and Frontline Gold may begin killing them as quickly as 30 minutes after application.

product tampering

ordered 8 count frontline plus. Received 2 of the 4 count packets which was ok. What was not was that both pakets had been opened. Whoever did that didn't even bother to cloth the packets correctly. They left the little side flaps hanging out. Will not use products that have been tampered with. Although the doses themselves appear in tact, I have no idea if they were swapped out for doses that had expired. Will not order from Chewy again. The button below asks if I would recommend this product to a friend. Yes I would but not through Chewy so I am selecting the no button.

DON’T WASTE YOUR MONEY DOES NOT WORK

Bought 6 does to treat my 3 cats. First dose did absolutely NOTHING. Like not one single dead flea. Used flea comb every day, home spray, vacuum etc. to control population. Thought maybe the drops just needed time to kill population. Applied second dose…NO EFFECT! What a waste of money. Contacted Chewy for a refund - they would only do partial refund. I have extremely limited income and buying these set me back. For them to not work on my two 19 yo cats who are miserable at the end of their life due to fleas hurts my heart.

Not Effective

Unfortunately, this was not effective in treating my cat. I used one dose and waited 24 hours and still saw fleas. I am not sure if this is authentic or if this was not effective due to my cats weight? It would be nice to have some reference for which treatments treat larger cats. This is not cheap, so the disappointment is definitely there with quality and effectiveness in treating the issue, especially when it is something like this, you want what you pay for to work to avoid a bigger problem or serious infestation.

Did not help ticks

I have used this for about 6 months now. This past month, which is tick season here, I am finding at least deer 2 ticks per day on my outdoor/indoor cat. They were attached and full of blood so they have obviously been there awhile. This product does not work for ticks! Beware if that is your main reason for purchasing!

It does work

For those that say it doesn't work it does work if you are starting with a flea free house my house got infected because I brought in a cat to babysit. you have to treat the house, bedding. I used Vets Best spray and I steam cleaned my floors and carpets. Once you have them you have to go all out and you can get it under control

So far so good

Using this with our five kitties. Switched after learning that the Advantage was no longer made directly by Bayer and having issues (2 kitties with fleas). So far, so good. Bonus is that my sensitive boy doesn't seem to mind the smell as much.

Doesnt work

Doesnt work at all. Took pets to vet for checkup and they said the same thing and offered me flea medicine they sold there that started working almost immediately. Dont waste your money.

Didn't work as well as I thought

I tried this for the first time on my kittens when I got it, they're currently on their second dose. However I still find fleas on them, every time I comb them I'm guaranteed to find at least 2 or 3 and they're still alive. It didn't work as well as I thought it would.

Nope. And, can't give any other flea meds for 30 days after using this

I rescue cats all year long, from Bronx, New York and for years this has been my go-to. No more. The fleas here are resistant to this product. I administered this to my 6 rescue cats on 8/24/2022. It did nothing. Six days later, in my PRISTINE, 2x daily cleaned cat foster room, with a fake wood floor, every surface sanitized, the fleas are still crawling through the cats' fur, perpetually dropping eggs. One week later I ran a flea comb through each cat (with a dish of water with dish soap next to me to dunk and kill the fleas from the comb), and each cat- omg the live, wriggling fleas. I have to give them all Capstar. Thank goodness I have a great foster-quarantine setup in my home which is so easy to clean. But heads up: the fleas in NYC have evolved to be resistant to this. Or maybe New York City has new types of fleas? Be super careful, don't trust this product, do not assume it will work as well as it used to.
