Okay, now I'm pretty scared that I am not putting this in the right section I bought some DE at my feed store and now I don't know if it is the right kind. I told the man that I wanted DE and he went and got it from a shelf. I don't know if there are other kinds/brand that they carry. What I bought is: Natural Guard "Gardening Nature's Way" Crawling Insect Control containing Diatomaceous Earth Active ingredients: silicon dioxide from DE 85%, other elemental oxides 10%, inert ingredients 5% After reading other posts on this topic, now I think I have bought the wrong kind. It has all these warnings on it and it doesn't say anything about being "food grade." Can someone please tell me if I should use this or not? Is this the bad kind?
