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.

It’s a good product and works great

It’s a really good product I just wish it had more natural ingredients and that it was more affordable for people to buy.

I Believe it works!

We've had a tough challenge with the recent flea issues. All the rain made it difficult to get these pesky pests out of our pets. This product is doing a great job! It smells great, and we have not seen any fleas after a couple applications. We've tried everything else you could image (bombs, collars, drops, bombs, other natural sprays.. did I mention bombs?) I would recommend this product before any others. Give it a shot (pun intended)

Doesn't work

Smelled good but I think actual perfume would have had more effect on the fleas.

Didn’t work on my dogs!

I have 2 chihuahuas who have been bothered by fleas lately! I rescued a baby kitten who was limping holding up his front paw outside and bathed her inside with cat shampoo that didn’t kill all of the fleas and eggs on her. So now my dogs and indoor cats and myself have been bitten by fleas?? Sprayed my dogs 3 times each in one week after bathing them too and still finding fleas on them. I will be buying something else since this brand isn’t killing the fleas on either animals.

This spray was fine for dogs, can go outside. Not so good for house cats. Will try another item.
