Rated 4.4 out of 5 by 5 reviewers.
Rated 5 out of 5 by Best product I've found It's been a long time since I've had to spray for fleas. I had a left over can from at least 10 years ago. Used it up and then went looking for another. Could not find this brand anywhere. Finally went on line and came to this site. Great price. After it dries there is no smell. It really does break the flea cycle. April 23, 2016
Rated 5 out of 5 by Works! I use this spray in my truck and it works every time. I did try spraying in my large bedroom once, and it did not work as well, however, admittedly I was not able to spray as much per square foot in the room as I was able to in my truck. Will be more generous in spraying the room next time, as soon as I can find my respirator! November 27, 2015
Rated 2 out of 5 by It did not work! I have tried several products on a flea infestation that we have. This was the least effective. It did not work at all. Tiny fleas were alive & biting after 24 hours. September 3, 2015
