Diatomaceous Earth: The Eco-friendly Pesticide Control

Posted on Posted in environment

Many people today have heard of diatomaceous earth although they may not understand the uses, benefits, and origins of this material. Maybe you’ve heard of using it as a natural pesticide or potential health benefits. This review breaks down the earth to help you get a better understanding.


Although its name suggests that it is a soil, diatomaceous earth is actually a porous sedimentary rock that is made up of the shells of diatoms. These are single cell plants of microscopic size which has siliceous shells. Over time, the shells have hardened into a lightweight but strong material known as diatomite. There are many areas where you can find deposits of this rock but one of the largest is in California. The shells are present in a chalky, clay-like formation which can be harvested and used for a variety of purposes.

Primary Uses

Although there has been a great deal of attention around diatomaceous earth in recent months, there are five primary uses of this material: pest control, farm and garden applications, pet benefits, human benefits, and industrial uses. We’ll break down how it’s used in each of these areas.

Pest Control

Bugs, fleas, and bedbugs can all be prevented or killed with the use of this material. The clay-like powder is a natural pest repellent and is often used in the place of chemical pest repellents. Most people use a flour sifter to sprinkle the material in cabinets, window sills, carpet, or anywhere pests may be present. It’s even used as a perimeter guard to prevent pests from entering. If you want to apply the material to upright areas, you can mix with water and apply just like paint. People will spray it on their trees or other areas where they want to reduce pests. It’s an effective method that is harmless to humans and pets.

Farm and Garden Applications

Many people use diatomaceous earth in their gardens or on their farms. It can be used in gardens or on farms to reduce pests from eating plants and won’t have any of the side effects of pesticides or chemicals. Many farmers also find that they will sprinkle the material on their animals to prevent mites or other pests. Finally, food-grade diatomaceous earth can be added to the feed of almost any farm animal such as chickens and sheep. It can promote digestive health and may help prevent any intestinal parasites as well.

Pet Benefits

Similar to use on farm animals, pet owners often swear by using this material with their pets. When using it on a family pet, be sure to purchase food grade. Although it’s not necessary for your pet’s health, the earth can be used to prevent fleas and some owners brush it into their dog or cat’s coat. It can also be added to their food for digestive health although not all pets will eat it willingly.

Human Benefits

The reason why people are including diatomaceous earth in their diets is that it’s gently abrasive and highly absorbent. As the earth is made from silica, taking it may have some benefit as silica makes up ligaments, muscles, and cartilage. As silica is also a compound that makes up hair and nails, it may improve the thickness and health of your hair and may help nails grow faster. As the earth is highly absorbent, it can help to improve digestive health, especially for anyone who struggles with constipation or irregularity. Finally, you may also find it being used in toothpaste or in facial scrubs for its slightly abrasive properties. All of these are potential uses.

Industrial Uses

Because of its dense nature, industrial uses of diatomaceous earth are many. It’s used in a variety of filters and can be used to process oils, beverages, solvents, and other chemicals, filtering out impurities. The earth is also a powerful insulator and can be used to insulate against changes in temperature as well as sound insulation. Finally, diatomaceous earth is used as a filler in a variety of materials such as paint, tile, soap, and detergent, just to name a few.


Most people have used products containing diatomaceous earth although you may not have realized it before now. This material has broad uses and can provide benefits in a variety of areas and can be used as a natural pesticide as well as other applications.
