I bought some at Wal Mart the other day and put it on Summerlin today. To begin with it smells really strong, but after a couple of hours the smell fades away (for the most part). It doesn't have that chemically smell that most have; instead, it is like an odd smelling incense. She went really crazy for a little bit, running around and burrowing into things - I guess the fleas were moving. I will brush her out tomorrow to see if I find any dead ones. I am hoping I do, or the 9 bucks will be wasted
