Diatomaceous earth (DE) is a naturally occurring powder made from the fossilized remains of tiny aquatic organisms called diatoms. With its unique properties, DE has gained popularity as a versatile, natural solution for a wide range of uses, from pest control to health and wellness. If you’re wondering what exactly diatomaceous earth is used for, you’ll be amazed by its applications both in and out of the home.
What is Diatomaceous Earth?
Diatomaceous earth is composed primarily of silica, a mineral that has a multitude of benefits. The sharp, microscopic particles of DE make it effective for killing pests, while its absorbent properties make it valuable in various industrial and health-related applications.
Common Uses of Diatomaceous Earth
Diatomaceous earth has a diverse range of uses, thanks to its unique structure and properties. Here’s a detailed look at its most popular applications:
1. Pest Control
One of the most popular uses of diatomaceous earth is for natural pest control. DE is highly effective against a variety of crawling insects, including ants, fleas, bed bugs, cockroaches, and more.
- How It Works: DE kills insects by adhering to their exoskeletons and absorbing the oils and fats from their outer layer, causing them to dehydrate and die.
- How to Use:
- Sprinkle a thin, even layer of DE in areas where pests are commonly found, such as along baseboards, under appliances, in cracks and crevices, and around entry points.
- Reapply DE after it gets wet or after cleaning.
Pros:
- Non-Toxic: Safe for humans and pets when using food-grade DE.
- Long-Lasting: Remains effective as long as it stays dry.
- Chemical-Free: A natural alternative to chemical pesticides.
Cons:
- Requires Reapplication: Needs to be reapplied if disturbed or exposed to moisture.
- Not Instantaneous: Takes time to work, as pests must come into direct contact with DE.
2. Health and Wellness
Many people use food-grade diatomaceous earth as a dietary supplement for its potential health benefits. DE is rich in silica, a mineral that is essential for healthy hair, skin, nails, and bones.
- How It Works: Silica is believed to promote collagen production, improve joint health, and support the strength of hair, skin, and nails.
- Common Uses:
- Detoxification: DE can help cleanse the digestive system by absorbing toxins, bacteria, and heavy metals.
- Internal Parasite Control: Some use DE to help eliminate internal parasites in humans and pets.
- Bone and Joint Health: The silica in DE is believed to support bone and joint health by aiding collagen production.
How to Use:
- Oral Supplementation: Start with 1 teaspoon of food-grade DE mixed in water, juice, or a smoothie once daily. Gradually increase to 1 tablespoon per day.
- Topical Use: Mix DE with water or oil to create a paste for exfoliation or as a natural scrub.
Pros:
- Natural Mineral: Provides a natural source of silica.
- Multiple Health Benefits: Claimed to support detoxification, hair growth, and bone health.
- Safe When Used Correctly: Food-grade DE is generally safe for consumption in moderate amounts.
Cons:
- Limited Scientific Evidence: More research is needed to fully support the health claims associated with DE.
- Potential Side Effects: Can cause digestive discomfort if not taken with plenty of water.
3. Household Uses
Diatomaceous earth is also a great addition to your household cleaning and maintenance routines due to its absorbent and abrasive properties.
- Common Uses:
- Natural Deodorizer: DE can absorb odors in refrigerators, trash cans, and closets.
- Stain Remover: Can be used to absorb oil spills and stains on carpets and garage floors.
- Mold and Mildew Prevention: DE’s moisture-absorbing properties help prevent mold and mildew in damp areas like basements and bathrooms.
- Polishing Agent: DE can be used as a gentle abrasive for polishing metals, silverware, and even teeth (as an ingredient in some natural toothpastes).
How to Use:
- Deodorizing: Sprinkle a thin layer of DE in areas where odor is an issue. Let it sit for a few hours and then vacuum or wipe away.
- Stain Removal: Sprinkle DE directly on oil stains, let it sit for a few hours to absorb, then sweep or vacuum it up.
- Polishing: Mix DE with water to form a paste and use it as a natural scrubbing agent for polishing and cleaning.
Pros:
- Multi-Purpose: Useful for a variety of household applications.
- Non-Toxic: Safe to use around the home.
- Highly Absorbent: Effective at absorbing moisture, odors, and stains.
Cons:
- Dust Concerns: Can create dust when used in large amounts; use in well-ventilated areas.
4. Gardening and Agriculture
In gardening and agriculture, diatomaceous earth is used as a natural pesticide and soil conditioner.
- Common Uses:
- Pest Control: Controls garden pests like aphids, slugs, beetles, and more without harming plants.
- Soil Amendment: Improves soil aeration and water retention due to its porous nature.
- Grain Storage: Used to protect stored grains from insect infestation.
How to Use:
- For Pest Control: Sprinkle DE around the base of plants and on leaves (for non-blooming plants) to deter pests.
- As a Soil Amendment: Mix DE into the soil to improve its structure and moisture retention.
Pros:
- Safe for Organic Gardening: OMRI-listed for organic use.
- Non-Toxic to Plants: Provides natural pest control without harmful chemicals.
- Improves Soil Quality: Helps retain moisture and improves soil texture.
Cons:
- Non-Selective: Can kill beneficial insects like bees if applied directly to flowers.
- Requires Reapplication: Needs to be reapplied after rain or watering.
5. Pet Care
For pets, diatomaceous earth can be used both externally and internally to support health and pest control.
- Common Uses:
- Flea and Tick Control: Applied to a pet’s coat to kill fleas and ticks.
- Internal Parasite Control: Given as a dietary supplement to help eliminate internal parasites.
How to Use:
- External Use: Lightly dust your pet’s coat with food-grade DE, avoiding the eyes, nose, and mouth. Rub it in well and repeat every few days as needed.
- Internal Use: Mix a small amount of food-grade DE (½ teaspoon to 1 tablespoon, depending on the size of the pet) into your pet’s food daily for a period of 30 days.
Pros:
- Natural and Safe: A non-chemical option for flea and parasite control.
- Multiple Uses: Can be used both topically and internally.
- Effective: Works well against fleas, ticks, and internal parasites.
Cons:
- Drying: Can dry out the skin if over-applied.
- Requires Caution: Careful handling is needed to avoid inhalation by pets or humans.
