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.

    I love the applicator!

    By emoly on Sep 27, 2019

    I love the applicator, it’s super easy to use. My dog hasn’t gotten fleas or ticks so I guess it works! I just really wish it smelled better. After I put this in my dog she smells kinda like old cardboard.
