Vitrsna---That is so true about the neem. But it is also good to put in your shampoo. I also use a toothpaste that has it in it. It is suppose to help get rid of gum disease. You could order food grade DE online for sure. But be sure it is food grade. When I see slugs I grab my salt shaker and sprinkle them with it. I guess it is not a vary humane way to get rid of them. Or I just squish them. I do not like them in my garden. I wish something would love eating them. I do have toads in the gardens and I have noticed that my slug count in down. So maybe they are eating those crummy little buggers.
