What Is Diatomaceous Earth and How Does It Work?

Diatomaceous earth, often abbreviated as DE, is a naturally occurring substance with a wide range of uses. It is valued for its effectiveness in everything from pest control to health and wellness. But what exactly is diatomaceous earth, and how does it work?

This article will explore the basics of DE, its properties, mechanisms, uses, and safety considerations to provide a clear understanding of this versatile material.

What Is Diatomaceous Earth?

Diatomaceous earth is a fine, powdery substance made from the fossilised remains of tiny aquatic organisms called diatoms. These diatoms are a type of algae that lived in ancient bodies of water millions of years ago. When these organisms died, their remains settled at the bottom of these bodies of water, forming thick layers of sediment. Over time, these layers fossilised, creating deposits of diatomaceous earth.

As the diatoms died and accumulated, their silica-based cell walls remained intact. This silica is a key component of diatomaceous earth and is responsible for many of its unique properties. The fossilisation process preserves the microscopic structure of the diatoms, resulting in a powdery material that is rich in silica.

Types of Diatomaceous Earth

Different kinds of diatomaceous earth are available, including industrial grade and food grade.  Food grade diatomaceous earth is safe for human and animal consumption, as it contains less than 1% crystalline silica

Industrial grade diatomaceous earth, on the other hand, contains higher levels of crystalline silica and is used for non-consumable purposes, such as filtration and pest control. It is important to use the correct type of diatomaceous earth for your intended application.

How Does Diatomaceous Earth Work?

Physical and Chemical Properties

Diatomaceous earth works through a combination of its physical and chemical properties. Silica, which makes up about 85 to 90 percent of DE, is its main ingredient. This silica is what gives diatomaceous earth its abrasive texture and high absorbency.

The microscopic structure of diatomaceous earth is what makes it effective for various uses. Under a microscope, DE appears as tiny, hollow cylinders with sharp edges. These sharp edges are what give diatomaceous earth its ability to cut through the exoskeletons of insects and absorb moisture, leading to their dehydration and eventual death.

Diatomaceous earth is highly absorbent, meaning it can soak up liquids and oils effectively. It also has adsorptive properties, which means it can bind to particles, toxins, and chemicals, making it useful in detoxification processes.

Mechanisms of Action

The mechanisms of diatomaceous earth vary depending on its application. One of the most well-known uses of diatomaceous earth is in pest control. When insects come into contact with DE, the sharp edges of the diatom particles cut through their protective exoskeletons.

This causes the insects to lose moisture and die of dehydration. Unlike chemical pesticides, DE is non-toxic and works through physical means, making it a popular choice for organic and environmentally-friendly pest control.

Diatomaceous earth is also used in health and wellness for its detoxifying properties. When ingested, DE passes through the digestive system, where it can bind to toxins, bacteria, and other harmful substances. These are then expelled from the body, potentially improving digestion and overall health. Some people also use DE for its supposed benefits to skin, hair, and nails, although more research is needed in these areas.

Uses and Applications of Diatomaceous Earth

Health and Wellness

Diatomaceous earth is used in a variety of health and wellness applications. Some people take food grade diatomaceous earth as a dietary supplement. It is believed to aid in detoxification, improve digestive health, and support nutrient absorption. You should consult a doctor before starting any new supplement and follow suggested dosages.

Externally, DE is used in skincare routines, hair care products, and even dental hygiene. Its abrasive texture makes it a natural exfoliant for the skin, and its absorbent properties can help control excess oil. Some people also use DE as a natural toothpaste for its ability to remove plaque and whiten teeth.

Pest Control

Diatomaceous earth is widely used in both household and garden pest control. In the home, DE can be applied in areas where pests like ants, cockroaches, and bed bugs are found. It’s important to use Diatomaceous Earth Food Grade Powder in these settings, especially if it will be applied in areas where pets or children may come into contact with it.

In the garden, DE can be used to protect plants from insects like aphids, beetles, and slugs. It is often sprinkled around the base of plants or directly onto the leaves. Because it is a physical rather than chemical control method, DE does not harm the plants or beneficial insects like bees when used properly.

Industrial and Environmental Uses

Beyond household and personal use, diatomaceous earth has several industrial applications. One of the most common industrial uses of DE is in filtration. Its porous nature makes it an excellent filter for water, beer, wine, and other liquids. It is used in both large-scale industrial processes and smaller, home filtration systems.

Diatomaceous earth is also used as an absorbent material in industries dealing with spills, especially those involving oils and chemicals. Its high absorbency helps contain and clean up spills efficiently.

Benefits of Using Diatomaceous Earth

Health Benefits

There are several benefits to using diatomaceous earth, particularly when it comes to health. One of the biggest advantages of DE is that it is a natural and non-toxic substance. Unlike chemical treatments, it does not leave harmful residues or pose risks to humans and pets when used correctly.

Diatomaceous earth is highly versatile, with applications ranging from health and beauty to pest control and industrial processes. This makes it a valuable addition to many households and industries.

Environmental Benefits

Using diatomaceous earth also has environmental advantages. DE provides an eco-friendly alternative to chemical pesticides. Since it works through physical means, it reduces the need for harmful chemicals that can contaminate the environment and harm non-target species.

Diatomaceous earth is a naturally occurring, renewable resource. Its abundant availability and minimal processing make it a sustainable option for various uses.
