Caution: avoid excessive dust in enclosed, poorly ventilated areas to minimize respiratory exposure during application.

Main advantage is OMRI Listing, offering assurance for organic use. Caution: ensure animals do not eat the powder directly and apply only to cracks, crevices, and affected areas as directed.
Garden Safe Crawling Insect Killer, 4 Pounds
Best for: Outdoor and garden use where an organic-friendly formulation is preferred. The product is designed for use outdoors and on plants, applying a thin layer of DE to soil and foliage.

Caution: as with all DE products, avoid inhalation of the powder and keep away from direct contact with eyes and skin. Reapply as needed after rain or heavy grooming of plants.

Buying Guide: Key Considerations For Diatomaceous Earth Dust Purchases
- Purpose and placement: Use indoor areas with high traffic or nesting pests for more impacts; apply outdoors for garden protection and on soil around plants.
- Grade: Food-grade DE is suitable for homes with kids and pets; for garden and gardening, organic-certified options may offer stronger compatibility with organic gardening standards.
- Application method: Powder dusters included in many bags simplify even dispersion; consider bags with built-in dusters for convenience.
- Safety: DE is a mechanical killer, not chemical. Still, avoid inhalation by wearing a mask during application and wash hands after handling.
- Storage: Keep in a dry place to prevent clumping and loss of effectiveness; reseal bags after use.
- Effectiveness: DE works best when pests cross the treated area; reapply after rain or heavy cleaning to maintain protection.
- Area coverage: A 4.4-pound bag typically covers a moderate indoor or outdoor area; larger spaces may require multiple bags or a larger size like 10 lb for sustained control.
