Product Reviews by Customers

Rated 4.3 out of 5 by 6 reviewers.
Rated 5 out of 5 by Powerful clove smell but Great product I have a 4lb Chihuahua. At first I was a bit worried about the smell of this after reading the reviews. Yes, it is strong for about two days. I followed the directions exactly and I used it outside. It smells like cloves and the lingering scent actually reminded me of the holidays. I had taken my dog to a friends where she was totally bombarded by fleas. After a bath I put this on her and everything stays away. Absolutely no sign of fleas, ticks and it keeps the mosquitoes away. She did a bit of rolling around on the ground as they usually do after being groomed. Avoid the face, nose, mouth and eye area and wash your hands thoroughly after handling your pet. I also found that it works as a great repellent to keep neighbors dogs out of my yard. It would be great if it were available in an industrial size container. August 16, 2012
Rated 3 out of 5 by Follow the application instructions. As others have said, my dog HATES the smell! After using this product he smelled like a spiced ham which is probably the best he's ever smelled. But, considering the ingredients, it makes sense that it smells that way, and in fact, I actually like it. But make sure you contact the skin the the spray and hold the fur back against the normal lay of it, otherwise the product might not get where it needs to be. Our dog had a large tick on him about 2 weeks after the first application, and I admit that I didn't exactly apply it as the instructions said to. I do know that it DOES kill insects instantly - I sprayed it on a wasp in flight and it dropped right to the deck! You can safely apply it as often as needed. Others have noted that it's important to spray it on the feet, since (in spite of popular belief), that's where many fleas and ticks get onto the dog. This product is a great idea, and if you haven't tried it you probably should. July 22, 2012
Rated 5 out of 5 by Love it I have four dogs,two of the dogs have very sensitive skin. This product works great the smell is an added bonus it's strong at first but tones down after a while. June 26, 2012
Rated 3 out of 5 by Useful in conjunction with I use it in conjunction with a more effective topical (Frontline) for hiking with my dog. I spray her belly, legs, lower chest and tail. Seems to keep the bugs away. I do not trust it totally to handle fleas--especially if you are in a bad flea area. May 17, 2012
Rated 5 out of 5 by Okay My dog hates this spray he actually ran off into the bushes to try to get it off when I put it on him. However, it is natural and it does its job. It has an overpowering scent but after a while it tones down and smells nice. I's like a built in cologne. My dog didn't have any allergic reactions and it does it's job. I have seen NO type of flea,tick or any other insect on my dog since I started using this. Overall it's a nice buy and I would recommend this all natural product. March 29, 2011
Rated 5 out of 5 by I love this stuff! My dogs aren't real enthused about it, but it doesn't hurt them or give them allergy attacks like the non-natural flea remedies. Bugs really hate this stuff! Kills any bug on contact, and now that fleas stay away, I buy it solely to kill and repel the ant population who tries to move into my house. Ants don't even try to go near this stuff! It has been a savior to me when I thought ants were going to carry off my house! And since it is pet-safe, the only bug-killer I feel safe using around my dogs! June 8, 2009
