Advantix does not work as well. **Q: Can anyone in florida give me your opinion on it’s effectiveness? i’m told that the fleas in fl are developing a resistance to some treatments.** A: I live in the Tampa Bay area in Florida and used this on my chihuahua for over 3 years and it has been very effective. I do not give him heart worm treatment since it repels and kills mosquitos as well and every time the vet has done his heart worm test, it has been negative. Therefore, I highly recommend this product, not only for fleas, which he has never had but for mosquitoes as well. **Q: Delivery on6-28?** A: Hi. Unfortunately, we’re not able to answer this question. We recommend you contact the seller for more information. ## Customer Reviews ### ⭐⭐⭐ Flea control liquid *by E***M on December 8, 2023* It was easy to apply but not as effective as others. ### ⭐ Hasn't Fully Worked *by J***Y on January 13, 2024* I live in the country and apparently fleas are just in the grass. I have treated my dog with this product and they continue to have fleas. ### ⭐⭐⭐⭐ Worked well *by L***A on July 17, 2023* This worked really well for one of my dogs. I have 2 tiny toy poodles one is 6# and one is 10#. Worked well with the 10# not so much for the 6#. Thankfully when I called the company they were very nice and helped me with my smaller pup, it was on a weekend and vet was closed. (she had a bad reaction). ## Frequently Bought Together - K9 Advantix II Small Dog Vet-Recommended Flea, Tick & Mosquito Treatment & Prevention | Dogs 4-10 lbs. | 3-Mo Supply - CAPSTAR Oral Flea Treatment for Dogs, Fast Acting Tablets Start Killing Fleas in 30 Minutes, Medium & Large Dogs (Over 25 lbs), 6 Doses - K9 Advantix II Medium Dog Vet-Recommended Flea, Tick & Mosquito Treatment & Prevention | Dogs 11-20 lbs. | 4-Mo Supply --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/502215143-k9-advantix-ii-small-dog-vet-recommended-flea-tick-mosquito](https://www.desertcart.us/products/502215143-k9-advantix-ii-small-dog-vet-recommended-flea-tick-mosquito) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-21*
