DiatomaceousEarth was created to provide consumers with the natural goodness of the earth. From the root word “diatom,” which is a single-celled organism, diatomaceous earth is a chalk-like powder that’s made up entirely of these diatoms that have fossilized over thousands of years. It’s found in lake beds that have dried up, and the exposed sedimentary silica deposits are then mined and ground into a powder, and that is what’s known as diatomaceous earth. It has a great amount of benefits for both pet and human uses, and interestingly enough, these benefits fall into the categories of health supplements and pest control—so it’s equally as good for the inside as it is the outside. The DiatomaceousEarth food grade powder is certified organic by the Organic Materials Review Institute, making it perfectly safe for pets and humans alike. And while there are different grades of diatomaceous earth, in its purest form it is totally safe to ingest and for use around the home.
