I live in Florida now, we just recently moved from NY, I didn't know the sand
fleas here are rampant, I have used the DE on my lawn and it has dried out the grass terribly that my dog will not even go there anymore, the grass is like hay now, her paws got very dry, so be careful when
putting it on your pet as it is a very drying
powder, but I have heard the only pill that really works here is Trifexis by prescription by a vet.
