The Food Grade Diatomaceous Earth label does not give instructions for mixing with water so we would not advise of this use. It is a dust that is applied directly in cracks and crevices around doors, windows, vents, places where cables, pipes and wire enter through the structure rather than all over the ground. This keeps the product protected and it keeps the product where pests are known to try and gain entrance into your home.
