Query: The fleas are gone but I am not sure if it was because of this product

I used advantage for my cat after not using it for a while. They were in our beds and i used this to try to get them out after changing the sheets. I don't like the fact that they tell you not to use it for humans but you can use it for pets. May be it's a law suit thing but I was looking for one i could use on my bed.
