I purchased this as a "Food Grade" Diatomaceous Earth. I assure anyone reading this that I have not tasted nor eaten any of this product (although some do to supposedly rid the human body of parasites and other wee beasties that go bump in the night?). I use this only for spreading on my vegetable garden. I 'puff' it onto the leaves. I have been using red Diatomaceous Earth for a numbe of years, since it is much cheaper. Both work by desicating insects by removing wax from their exoskeltons and allowing bodily fluids to evaporate. Further, the DE gets into insect joints and creates more chaos. Is this more humane than insecticid? Perhaps not, but it is perfectly safe for humans (since we are so much larger and don't have exoskeletons (our skin keeps us moist on the inside). This white food grade seems much finer that the red (I didn't look with my microscope). Ergo: I think it is more tenacious regarding the leaves and insects. I have definitly seen a reduction in squash bugs, aphids, potato beetles, and other riffraff. Anyway: I ordered this on-line and did a store pick-up. I was not asked for ID and merely pointed to my item. I left the store and put in the rear of my car. Voila! One thing I must add...wear goggles and a mask when spreading. Perhaps, gloves if you have trepidation. And until you clean up...everything you touch will have a fine white powder left on it. My shed door once was red and now is white. Of course, it will come off...but not without rinsing.

This is a good product but I'm giving it one star until they change the answer to one of the questions about the product. The person asked if it could be harmful to cats if it is inhaled. It can be harmful if inhaled but whoever's answering the questions answered only that it is safe for pets. . I will update to 5 stars when they change that answer.
