Black Soldier Fly Larvae (BSFL) are the nutrient-rich larval stage of the Black Soldier Fly, Hermetia illucens. Unlike nuisance flies, BSFL are clean, efficient decomposers that naturally consume organic material and transform it into valuable biomass. They are naturally rich in protein, fats, minerals, calcium, phosphorus and other nutrients, making them an excellent supplemental food source for poultry, reptiles, fish, wild birds and other animals. Their natural feeding behavior also makes live BSFL an excellent enrichment food, allowing animals to forage while receiving valuable nutrition.

BSFL are valuable far beyond animal feed. These remarkable insects are part of a natural resource-recovery system: they consume suitable organic materials, rapidly grow, and convert those resources into usable insect biomass while producing frass as a secondary product. Compared with traditional animal protein production, insect production can require significantly less space and resources, making BSFL an exciting component of more sustainable agriculture and feed production.

At GrubForge, we see BSFL as more than just a feeder insect—they are nature's little recyclers and nutrient factories. We raise them to transform organic resources into high-quality, useful products for animals, farmers, gardeners and growers. From a handful of larvae feeding backyard chickens to large-scale production for animal nutrition, BSFL offer a practical connection between sustainable resource recovery, nutritious animal feed and a more circular agricultural system.

BSFL frass is the nutrient-rich material left behind as Black Soldier Fly Larvae feed, grow and process organic material. It contains insect manure along with residual organic material and shed insect material, depending on how it is produced and processed. Rather than being waste, properly produced and processed frass can be a valuable soil amendment containing organic matter, nutrients and biologically active components, including insect-derived chitin.

Frass can help return valuable nutrients and organic matter to the soil while supporting the biological processes that make healthy soil possible. It is used by gardeners, growers, greenhouses, landscapers and agricultural producers as a soil amendment, and its combination of nutrients, organic material and insect-derived compounds makes it an exciting natural input for growing healthier plants and maintaining productive soil.

At GrubForge, nothing valuable goes to waste. The same biological process that produces nutritious BSFL for animals also produces frass for the soil. It completes the cycle: organic resources become larvae, larvae become nutrition, and frass returns nutrients and organic matter to the earth. What begins as an organic resource can become two valuable products—one for animals and one for the soil.
