Query: Does not work

I bought this product thinking it would get rid of fleas on my dog, instead it did the opposite. I used it and saw that it draws fleas to your pet and then sterilizes them, not kill them. So it uses your pet as bait to get the fleas and then the fleas die after a few days, but this does not stop the fleas from biting your pet. So this was not a great product and the reviews never mentioned this. So I was not happy with this product and will never purchase this again.
