Just thought I would mention that Diatomaceous earth does not kill bugs by having them eat it. It is a dessicant and is abrasive to the waxy cuticle on the insects body... so they dry out. If you look at it closely you would see it has many sharp edges, they are made out of the fossil bodies of Diatoms.... The stuff that bugs eat and die from are BT or Sevin.... One causes an 'insect cold' and the other is a stomach poison.
