Diatomaceous earth (DE) is a popular natural product with a variety of uses, from pest control to pool filtration. It’s made from the fossilized remains of diatoms, a type of algae with hard shells made of silica. When diatoms die, their shells accumulate in sediment layers, which are mined and processed to create DE.
But did you know that not all DE is created equal? You’ll find two main types: food-grade diatomaceous earth and diatomaceous earth designed for insect control. While they might look similar, there are important differences between the two that impact their safety and applications.
This article will explore the differences between food grade and insect killer diatomaceous earth, providing valuable insights to help you make informed decisions about which type is right for your needs.
Understanding the Different Grades of Diatomaceous Earth
The key difference between food-grade diatomaceous earth and insect killer diatomaceous earth lies in their processing and silica content. Let’s delve deeper into each type:
1. Food-Grade Diatomaceous Earth:
- Processing: This type of DE is carefully processed to remove impurities and ensure it meets strict safety standards for human consumption. It’s typically heated to a high temperature to eliminate moisture and any potential contaminants.
- Silica Content: Food-grade DE contains a lower percentage of crystalline silica, usually less than 2%, making it safe for ingestion in controlled amounts.
2. Insect Killer Diatomaceous Earth:
- Processing: Unlike its food-grade counterpart, insect killer DE undergoes minimal processing and may contain a higher level of impurities.
- Silica Content: This type boasts a higher concentration of crystalline silica, often exceeding 80%. This crystalline structure is what gives it its insecticidal properties. The sharp edges of the silica particles effectively cut through the exoskeletons of insects, leading to dehydration and death.
Why Using the Right Type of DE Matters
Choosing the wrong type of diatomaceous earth can have undesirable consequences. Here’s why using the right DE is crucial:
1. Health and Safety:
Using insect-grade DE for consumption can pose health risks. The high concentration of crystalline silica in insect-grade DE can be harmful if inhaled in large quantities, potentially leading to respiratory problems.
2. Effectiveness:
Similarly, using food-grade DE for insect control might prove ineffective. The lower silica content in food-grade DE makes it less potent in damaging insect exoskeletons, reducing its ability to eliminate pests.
Choosing the Right DE for Your Needs
Selecting the appropriate type of diatomaceous earth hinges on your intended application. Here’s a simple guide:
Choose food-grade diatomaceous earth for:
- Dietary supplement: Some people use food-grade DE as a supplement due to its silica content, which is believed to have potential health benefits. However, it’s crucial to consult with a healthcare professional before incorporating DE into your diet.
- Food storage: Food-grade DE can help prevent infestations in stored grains and other dry goods.
Choose insect killer diatomaceous earth for:
- Pest control: Use this type to eliminate a range of crawling insects, including ants, fleas, bed bugs, and cockroaches. Apply it around the perimeter of your home, in crawl spaces, and in areas where insects are commonly found.
- Garden pest control: Insect killer DE can deter slugs, snails, and other garden pests. Sprinkle it around your plants to keep these critters at bay.
Using Diatomaceous Earth Safely
Regardless of the type of DE you choose, it’s essential to prioritize safety. Here are some tips for handling and using diatomaceous earth responsibly:
- Wear a mask: When applying DE, especially insect-grade DE, wear a dust mask to prevent inhalation.
- Protect your eyes: Safety glasses are also recommended to shield your eyes from irritation.
- Keep away from children and pets: Store DE out of reach of children and pets.
- Apply in dry areas: DE works best in dry conditions, so avoid using it in excessively humid environments or on wet surfaces.
Frequently Asked Questions About Diatomaceous Earth:
1. Is food-grade diatomaceous earth safe for pets?
Yes, food-grade DE is generally considered safe for pets, often used as a natural dewormer. However, always consult your veterinarian before giving any new supplements to your pets.
2. How long does diatomaceous earth last?
Diatomaceous earth has an indefinite shelf life if stored properly in a dry and airtight container.
3. Can diatomaceous earth be used in a garden with beneficial insects?
While DE is effective against many pests, it can also harm beneficial insects like ladybugs and bees. Use it cautiously in gardens, targeting specific areas where pests are a problem.
4. How often should I reapply diatomaceous earth for pest control?
Reapply DE after rain or watering to maintain its effectiveness. You can also reapply it every few weeks for ongoing pest prevention.
