Black Soldier Fly Frass 3-1-2

Chitin-Rich Organic Fertilizer | Microbial Booster | 100% Renewable

Black Soldier Fly Frass is a sustainable, insect-derived fertilizer made from the manure and shed exoskeletons of black soldier fly larvae. Rich in beneficial microbes, plant-available nitrogen, and natural chitin, this all-natural input promotes healthy plant growth, improves soil structure, and builds resilience in fruits, vegetables, lawns, and ornamental gardens.

Sourced from larvae raised on clean, traceable, pre-consumer food waste (vegetables, fruits, and grains), this frass is a 100% renewable resource that supports a circular, waste-free nutrient cycle.
