Diatomaceous Earth Perma-Guard Fossil Shell Flour

Diatomaceous Earth - Perma-Guard Fossil Shell Flour

Natural Pest Control, Soil Conditioner & Mineral Additive

Perma-Guard Fossil Shell Flour is a food-grade diatomaceous earth (DE) made from the fossilized remains of ancient freshwater diatoms. Mined and milled into an ultra-fine powder, it offers a chemical-free, mechanical solution for controlling soft-bodied insects and improving soil structure.

This versatile mineral product is ideal for garden pest management, animal housing, grain and seed storage, and as a natural soil conditioner for increasing silica and improving texture.

Key Characteristics

• Insect Control Without Chemicals
  Diatomaceous earth works by physically damaging the exoskeletons of insects, causing them to dehydrate. It is highly effective against ants, fleas, mites, earwigs, slugs, and crawling insects in the garden or greenhouse-without harming earthworms, pollinators, or soil biology when used properly.

• How to Use in Garden, Home, and Storage

  • Garden pest barrier: Lightly dust leaves, stems, and soil surface around plants. Reapply after rain or irrigation.

  • Chicken coops and barns: Sprinkle in bedding, nest boxes, and corners to reduce mites and lice.

  • Seed and grain storage: Mix 1-2% DE by weight into stored grain to prevent weevil and larval infestation.

  • Compost and soil: Add ½-1 cup per cubic foot of soil or compost to increase silica and improve texture.

• Improves Soil Texture and Mineral Balance
  Diatomaceous earth contains 85-90% silica, which supports plant cell strength, resilience, and nutrient uptake. In clay-heavy or compacted soils, it helps improve aeration and drainage when mixed in small amounts.

• Safe, Non-Toxic, and Versatile
  This food-grade product is non-toxic to humans and animals, making it a safe option for use around pets, livestock, and children. It's also OMRI-listed for organic production.
