St. Gabriel Organics® Good Earth Diatomaceous Earth — 4 lb — OMRI Listed®

Food-Grade Diatomaceous Earth for Crawling Insects & Feed Storage, 4lb

Crawling insects in the garden and moisture-driven caking in stored grain and feed are two different problems that usually call for two different products. Good Earth Diatomaceous Earth by St. Gabriel Organics handles both with one bag of 100% food-grade diatomaceous earth (DE) — a fine fossil-shell powder that abrades the exoskeletons of crawling insects on contact, causing fatal dehydration, while also preventing clumping in stored grains, seeds, and animal feed.

This 4lb bag is sized for home gardens, small coops, and household pantry or feed storage — enough for a full season of spot dusting without the bulk of a farm-size container.

Key Features & Benefits

• 100% Food-Grade Diatomaceous Earth — no added chemicals or fillers, just fossilized diatom shells ground to a fine powder.
• Mechanical Pest Control — abrades the exoskeletons of crawling insects, causing dehydration rather than relying on a chemical toxin.
• OMRI Listed — certified for use in organic production and organic gardening programs.
• Dual-Purpose Use — works as a pest control dust in the garden and as an anti-caking agent in stored grain, seed, and animal feed, including dog and cat food.

Who Should Use This

Home gardeners dealing with crawling insects on plants or in garden beds, and anyone storing grain, seed, or pet and livestock feed who wants to prevent moisture clumping without synthetic anti-caking chemicals.

Frequently Asked Questions

How does diatomaceous earth actually kill insects?

Food-grade DE is a fine powder made from fossilized diatom shells. It abrades the waxy outer layer of a crawling insect's exoskeleton on contact, causing the insect to lose moisture and dehydrate, rather than acting as a chemical poison.

Is it safe to use around pets?

Yes. Good Earth Diatomaceous Earth is labeled safe for use around dogs, cats, and birds, and food-grade DE is also used as an anti-caking additive directly in pet and livestock feed.

Can I use this on food crops?

Yes. As an OMRI Listed, 100% food-grade product, it's suited to organic vegetable gardens and other food-crop applications. Always follow the product label for specific application guidance.

Does it work once it gets wet?

Diatomaceous earth loses its abrasive pest-control effectiveness when wet, since moisture lets insects move across it without the mechanical abrasion effect. Plan to reapply after rain or irrigation once the treated surface dries out.

What's the difference between food-grade and pool-grade diatomaceous earth?

Food-grade DE like Good Earth is processed to remove crystalline silica and is safe for garden and feed-storage use. Pool-grade DE, by contrast, is chemically treated and heated for filtration and isn't intended for pest control or feed applications.
