Some places sell the diatomaceous earth (food grade) mixed with other stuff. And that is something I do not recommend. When I see a label that says "97% diatomaceous earth" I have to wonder what the other 3% is. If the packaging is about killing bugs, is it some sort of toxin? Did they add something like borates or pyrethrin for a little extra kick? I don't want that!
