National Diatomaceous Earth Day

National Diatomaceous Earth Day is dedicated to raising awareness of diatomaceous earth, also known as diatomite or kieselguhr. It is celebrated annually on August 31st and is intended to inform people of diatomaceous earth’s diverse uses.

Most people are familiar with diatomaceous earth, as it is commonly used to filter water in pools, or as a natural insecticide to control pests in gardens. It is a white powder which is obtained from fragments of algae collected in dried river and lake oxbow lakes. Aside from its use as an insect control chemical, it also has other special properties, such as detoxifying the body, acting as an antioxidant, having antibacterial, antifungal, and antiparasitic properties, aiding digestion, and lowering cholesterol. History

National Diatomaceous Earth Day was established in 2016 by EP Minerals.

Interesting facts

The largest diatomite deposits can be found in the north of Santa Barbara, California.

How to take part

If you’d like to take part in National Diatomaceous Earth Day, here are some suggested activities:

  1. Enjoy sugar syrups, fruit juices, wines, and other foods where DE is used as a filter material.
  2. Decorate your room, as DE lengthens primary pigments, increases bulk strength, and improves coating adhesion to paints.
  3. Work in the garden. DE is an effective natural insecticide that causes dehydration to kill pests, and can also be used as a fertilizer for soil aeration. It can also be used to repel pests from the home, such as fleas, bedbugs, and ants. Additionally, it can be used to protect pets’ fur coats before a walk in the woods – just make sure not to get it near the pet’s nose, ears, and eyes.
