What is Frass?
Mealworm frass is a natural soil amendment that supports soil biology, provides gentle, slow-release nutrients to plants, and has been shown to support plant resilience and natural defence responses.
What makes this product different:
Most frass on the market is sifted through large, coarse mesh, which leaves a significant amount of bran and feed particles mixed in. That means you’re not actually getting pure frass—you’re getting frass plus leftover substrate.
This product is sifted using a #30 screen (600 microns), which removes the bran and retains only the fine, high-value material:
-
Mealworm castings
-
Micro chitin from shed skins
-
Beneficial microbes
The result is a cleaner, more potent fertilizer with consistent particle size and superior nutrient availability.
Why it works:
-
Higher purity = higher effectiveness. More actual frass per gram means better nutrient density and better soil biology.
-
Chitin-rich, which stimulates natural plant defenses and supports stronger roots.
-
Slow-release NPK that won’t burn plants.
-
Boosts microbial activity and improves soil moisture retention.
-
Low odor and non-toxic for indoor and outdoor use.
