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 30 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.

help fleas!!!!

For the last 18 months we have been battleing fleas. We have tried Advantage II , Steel Dogs, Adams dip and a Vet. applied topical. The fleas only laughed. They are so big you could almost fry them for supper. I have granulated the yard and had a professional granulate the yard. I have sprayed the yard with Adam's flea spray. We found a peppermint spray that did give the dogs some relief temporarily. Now we have tried this product. My dogs are all sleeping in their beds. This is not 100% but it has given us a big adavantage. Between this, shampooing, and keeping beds washed and cleaned, I believe we may have turned a cornor. Thank you so much.

Brand my puppy's vet recommends

I purchased this for my wheaten terrier puppy. It's the same brand that his vet recommends and sells at their office, but much more affordable and more convenient.

First time using. I like the idea it kills mosquito's because we live by a pond. No reactions since applying n I see no fleas, ticks or mosquitos.
