Be careful if you are going to use the diatomacious earth (DE). It is a very fine powder, can get airborne very easily and can irritate the airway. I have read that you need to use the "food grade" DE. I use it in the pool filter (DE) and quickly found out how powdery it is. The beneficial nematodes might be the better way to go.
