Customers say
Customers find the flea and tick treatment effective and easy to apply, taking less than a minute to apply, and consider it better than Frontline in terms of quality. Moreover, the product is affordable, and customers report it doesn’t cause noticeable skin reactions or sores. However, experiences with flea control and duration are mixed – while some say it kills fleas effectively and lasts a whole month, others report it doesn’t work at all and doesn’t last 30 days. Additionally, opinions on the smell are divided, with some saying it doesn’t smell horrible while others find it terrible.

Great for a 2nd line of defense.
This is identical to K9 Advantix II. This product works great for my dog, but then again my dog’s skin doesn’t have severe reactions to permethrin. Permethrin is extremely deadly when used incorrectly. For instance undiluted permethrin spray used on goats with direct skin contact will send a goat into nervous system failure within 2-4 minutes. They loose control over their bladder. Their back legs shutdown. The goat will continuously stretch out long and it’s legs get wobbly and their steps get very uncoordinated. If the permethrin isn’t removed from the goat’s body with soap that has sulfates in it, in order to break down the molecule structure compounds of the permethrin, then the goat will go into seizures and die. If permethrin can do all of that to a goat, just imagine what it can do to your dog. If permethrin is used properly and dosed correctly it has proven to be very safe and effective, compared to many pesticides used on livestock and pets.Please, when testing any pesticide product on your pet, only test a small penny size area to start. Just like you don’t slather your face in a new unknown facial cleanser or cream due to possible skin reactions, you don’t go pouring pesticide products on your dog’s skin if they have never been introduced to the product prior before. Common sense goes a long way.Personally, this product works wonders for my English Mastiff. This isn’t a fix all product though. If your dog already has fleas or ticks they need removed with a few baths soaked in Dawn dish liquid original. This product will NOT remove or kill off a current infestation. I know what the product claims, but as a goat farmer who has actually worked with undiluted permethrin; which is the active ingredient in this product, there isn’t nearly enough permethrin in this product to kill off a full blown tick of flea infestation. This product is a good deterrent and keeps pests from wanting to bite and start a infestation.If you apply this to your dog and get a odd reaction within the first 5 minutes, then you should react VERY quickly. Use a soap with sulfates in it, such as Dawn Dish liquid original. Use cold water also to stop the skin pours from opening up and enlarging, which would allow more of the pesticide residue into the blood stream. Scrub and wash the affected skin area, vigorously. Do not toss water on or dunk the affected area. By not scrubbing the pesticide residue away from the skin and minimizing the effect of it soaking in deeper past the dermal layer, you’re only wasting precious time. Scrub, scrub, scrub.I’ve used permethrin for a long time as a goat farmer. Around and in my barns. In our milking area and on our milking stands. In chicken coops and duck houses. In our buck barn and around common areas in the pasture. Also use it in our basement to keep out hundreds of pests. This product is a good product, but never let your guard down. Always be looking for ticks, fleas, mites, lice, etc. Do your best to minimize exposure, period. This product is for 2nd line of defense. This product is NOT a cure all fix all, 1st line of defense kinda product. But then again neither are the real expensive Rx script chewable tablets either. Been there, done that.

Effective, Affordable and easy to apply
Best topical flea & tick prevention I’ve ever used. I’m a small hobby breeder of Pomeranians, been raising dogs for 20 plus years, I’ve used it all! Advecta Ultra is superior to any other products on the market for the price.

This product works pretty well and is easy to apply. Must treat the house and yard for best results
Samantha –
Surprisingly good
Works pretty well. Noticed a decrease in my dogs itching. Didn’t fully get rid of fleas but I’m still trying to break the cycle, so not really the products fault. In my opinion works just was well as name brand flea treatments.
Amazon Customer –
Fleas on steroids
It worked for about 3 or 4 days, then the fleas were back. It’s not just this product, though. I have tried Seresto collars, which have worked well in the past, Amazon brand and another over the counter monthly drops, Adams flea spray, Adams flea collars, Furr life flea collars, Triazinon yard spray, Vets Best flea spray, Pestie (love them. They sent me some different kind of spray to try. Have to wait for a couple of dry days before I can), and last night I tried Bug MD. So far, so good with that, but it hasn’t even been a whole day. Crossing my fingers. I do not have the money to take my 5 dogs to the vet for flea treatment and they hate going so much. The fleas are on steroids this year.

Works Great
This stuff works great. No skin irritation on either my GSD and the Terrier. No fleas or ticks at all. I also use Advecta for the cats and have no issues with it there, either. Now if the cats would just leave the Christmas tree alone…
T. Harris –
Effective and affordable
Been using this for years and it works great. I live in a wooded area so fleas, ticks and mosquitoes are plentiful here. This is affordable, easy to apply, and it works as well as the other more expensive ones.
Kailey Reich –
Much better than other brand names!
I’ve ordered this the past three months for all 3 of my dogs. We have a large field the city owns behind our property and we get fleas bad from it. This has been a lifesaver for us since our backyard where we let them out goes into the field past our fence. Works much better than the Frontline Plus I was buying before!
