Unfortunately am more disappointed than happy about this product. Unfortunately I have to struggle for some time with mild in the henhouse. Chemi brought nothing and have since all raved about Kiselgur I thought I get so the problem under control. When 1 application I thought then but nothing positive to be surprised because even crawling on everything. So I figured the more the better so the stall cleaned after 1 week still ma and a lot of anti forte pure. 2 days later I looked in the barn and a few spotted mites. The chicken I have also dealt with. Although it has destroyed but the mite does not reduce all.
