Rated 4.4 out of 5 by 18 reviewers.
Rated 5 out of 5 by Great for ticks! Perfect price! We don't have a lot of fleas, so I can't speak for that, but we do have ticks, and we hunt and compete in a lot of places that have ticks. Bio-Spot has, by far, help up and at a far cheaper price than other topicals. June 13, 2016
Rated 5 out of 5 by Effective I have 5 dogs ranging from small to large and buying anything for all 5 can get expensive quick. I never sacrifice quality and safety for low costs. I have tried these on all of my 5 dogs and have not seen fleas or ticks or any side effects. We live in Texas were it can be flea, tick and mosquito season all year long so I need things that work. My dogs are usually inside dogs the most time they spent outside will be 4 hours because of the heat so I have not tested it 24 hours 7 days a week outdoor exposure to pets. The liquid can be easily seen after applying and depending on the dog hair could probably linger or be noticeable but they arent bothered by it. May 25, 2016
Rated 1 out of 5 by Does not work My dog normally scratches about 10 times a day. With this new product, it seems that he is scratching the same number of times plus even a bit more. I don't think he is allergic to this, as she is not allergic to anything, but I will definitely be seeking a refund. May 5, 2016
Rated 5 out of 5 by This product is easy to use I have used several different flea and tic products and have found this is the best! ! I have four cats and one dog and it works on them all. Easy to use and no odors. April 19, 2016
Rated 4 out of 5 by Good product. Applicator was confusing. Product worked well. Must be applied in several places. April 15, 2016
Rated 4 out of 5 by Good stuff I have used biospot for 15+ years. Excellent product at a very reasonable price. I don't see any fleas or ticks on my dogs where as my gsd contracted lymes disease while on frontline as a puppy. My dogs are search dogs so we spend a lot of time in the woods. Great product and doesn't cost me an arm and a leg! April 14, 2016
Rated 5 out of 5 by This product did a great job. Bio spot did a great job for both our dogs last summer. I was worried that it was less expensive than other products, it may not work well. But it did a great job. No ticks or fleas all summer. March 23, 2016
Rated 4 out of 5 by Bio Spot I like how easy the application is. My dogs DO NOT have fleas and I have been using this product for about 10 years. I have notice the older my dogs get {I have one that is 15} the more it looks like she has a oil slick on her back. But a simple bath helps {I give her one about 5 days after the application} March 14, 2016
