Bests & Worsts Reviews from Amazon

I ran the following experiment to test the ability of this product to kill fleas. With the help of my son, I collected 12 fleas from the dogs and placed them in a jar and observed that all were alive and hopping about. I then did one spray into the jar. Yes, just one spray. In about 10 seconds all fleas were dead! Then, my son suggested another test: "let's collect some more and put them in the sprayed jar", he said. We did that also, and the fleas died within a few seconds. I'm sold.
