Rated 4.4 out of 5 by 26 reviewers.
Rated 3 out of 5 by flea overload I have used this product a number of times. It worked very well when I lived in northern Illinois. I moved to Nashville, TN recently. It worked great at the beginning of spring. A couple of months later, it hardly worked at all. Not only did he get infested all 3 of my indoor cats did too. Yes they get treated every month too. Fleas are a big problem down here. Especially if the tempreture does not drop below freezing over the previous winter. I have also always treated my yard every year for fleas. My dog is a 90 pound long haired German Shepherd. It gets very hot down here so I don't leave him out for long. We need super strong stuff down here. December 17, 2016
Rated 1 out of 5 by Product does not work Product does not work! Every dog I used this product on still has fleas. December 29, 2016
Rated 5 out of 5 by great product I have been using this product for my dog Kane for a long time and no fleas at all. December 15, 2016
Rated 5 out of 5 by Great for the price! So if you read the box, it repels ticks & mosquitos, but NOT fleas. It does KILL fleas, but does not repel them. Knowing this going in, it has worked perfectly for my dogs. I have 4 dogs ranging from 6 to 96 pounds and I use this on all of them. I give my large dogs a bath once per month and my smaller dogs every other week. I have noticed fleas on my pug, but only a couple, and they were all dead. I keep Advantage II on my cats, and I don't have carpet in my home so infestation is a non-issue for me. Overall I'm very pleased with this product and I will continue to use it on my dogs.

Rated 5 out of 5 by Efficient repellant This is one of the few repellants that works against ticks, fleas, AND mosquitos. And the price is lower than some of the repellants that work only on ticks and fleas. October 17, 2016
Rated 5 out of 5 by good quality, good stuff. I used this on my larger dog for a year, had NO problems with fleas, ticks. ... no bug issues at all. Then we got an Aussie doddle mini, used a"companies brand with similar price and ingredients. Mocha got and kept fleas, itching, rubbing on carpets, dispite baths, sprays even powder. I was going crazy. I had to go to Chewy to find this brand, and the right dosage for Mocha. She's 6lbs. Our other is 30lbs. I got it in 2 days, standard shipping! applied it immediately. Mocha quit itching within an hour. We'very not seen or found 1 flea since application. We love this brand! For the cost it works great! August 20, 2016
Rated 5 out of 5 by Bio Spot works best! I live next to fish and game property. I want my dog to have a product that not only stops the next generation of fleas and ticks but also any living ticks or fleas. I couldn't find this product at my pet store and was so thankful to finally find it on Chewy.com. I have a peaceful happy 10 year old German Shepherd who has worn this since she was a puppy and has never had fleas or ticks or health problems! Thank you! August 9, 2016
