This was quite a trip, just finding it. The people around here look at you like you don't know what you want and this was at Dicky Bubs farm supply. They also said they never heard of it and couldn't find it on their computor. I also asked about an electric water base and all they could show me is dog bowls. Well, I went to look at the chicken supply area and there it was, the electic water base! I went to another farm supply and did find the DE but again, it was a search and it was their last bottle. So what I need to know is, how to use the DE and how often? I also intend on using it on my dogs for their flea problem, I heard it works well. A few quik answers will be fine. THANKS!
