Diatomaceous earth, also called Kieselguhr, light-coloured, porous, and friable sedimentary rock that is composed of the siliceous shells of diatoms, unicellular aquatic plants of microscopic size. It occurs in earthy beds that somewhat resemble chalk, but it is much lighter than chalk and will not effervesce in acid. Under a high-powered microscope the form of the diatoms can be distinguished.

1. Kieselguhr, a diatomaceous earth (diatomite) is a form of silica composed of the siliceous shells of unicellular aquatic plants of microscopic size. Kieselguhr is heat resistant and has been used as an insulator, as a component in toothpaste and as an abrasive in metal polishes.
. DE mixed with water is commonly known as a slurry. To make a DE slurry, follow this ratio: ½ cup DE (8 tablespoons) for 2 cups of water. You can apply the slurry with a spray bottle or a pressure washer. Once you mix the DE in the water, the DE will settle to the bottom, so you need to shake it up frequently as you spray.

· This answer to this question is complicated because diatomaceous earth is produced in two forms: the food-grade and the filter grade. The food-grade type is considered safe for human use and consumption because it is low in crystalline silica. However, the filter grade form is rich in crystalline silica, making them very toxic to human use.
