Query: Don't waste your time or money!

This so isnt like the product is described at all. I have used Diatomacous Earth food grade before and it worked for everything. This stiff is useless. Its been well over two weeks and it has had no effect. Dont waste your money. You might as well fling flower everywhere, you would get the same results. Seriously buy another brand or something. This stuff does NOT work!!!
