i use this stuff for everything! from keeping ants out of my house, to de-fleaing the pets, to taking for a detox for myself… this stuff is “magic”. i never put any poisons on anything in my gardens but DE makes it possible to still grow organically while killing those little suckers! i buy the FOOD GRADE ONLY in 50 lb. bags. i even bought a bag for my mom and she thinks it’s wonderful, as well. check out the article…it’s informative and helpful.
