I've bought some of these in the past and they work great. This seller sells the real version you can see their Elanco logo on them. They have a powdery vs glossy sheen that the fake ones have and oh. These kill fleas.It's been a bad season for fleas. When diatomaceous earth, various repelling oils and the usual tricks don't work we default back to these. They work every time. They don't irritate my dogs.
