Crafted onsite in Oregon by the wizards at Soil Sorcery, our Black Soldier Fly Insect Frass (3-1-1) is a nutrient-rich organic fertilizer made from the castings of black soldier fly larvae fed on clean, local fruit and vegetable waste and grain-based feeds. This living soil amendment is brimming with plant-available nutrients, beneficial microbes, and natural biostimulants like chitin, which help activate your soil's immune system.

This frass is not just fertilizer—it's a biological awakening for your garden, ideal for jumpstarting microbial life, enhancing nutrient cycling, and building resilience from seedling to harvest.
