Blue Grub Farms: Black Soldier Fly Larvae (BSFL) FAQ

BSFL as Feed: Nutrition and Use

1. What does BSFL mean, and what are they?

A: BSFL stands for Black Soldier Fly Larvae (Hermetia illucens). They are the juvenile stage of a non-pest, non-biting fly. They are nature's ultimate recyclers, rapidly converting organic waste into two highly valuable products: high-protein insect biomass (feed) and nutrient-rich Frass (soil amendment).

2. What is the calcium content of BSFL?

A: This is a crucial nutritional factor! The verified benefit of BSFL is their ideal mineral profile. Black Soldier Fly Larvae have a naturally high Calcium-to-Phosphorus (Ca:P) ratio, typically 1.5:1 or higher. This ratio is essential for preventing metabolic bone disease in reptiles (like bearded dragons) and supporting strong eggshell formation in poultry.

3. Are BSFL suitable for bearded dragons, chickens, and other pets?

A: Yes. BSFL are an excellent feed source. They are particularly beneficial for bearded dragons due to the high Ca:P ratio. They are also highly recommended for chickens, ducks, and wild birds as a natural, engaging protein and fat supplement.

Frass, Equipment, and Farming

4. What is Frass, and how does it benefit my plants?

A: Frass is the natural byproduct of BSFL—their dried excretions and shed exoskeletons. It is a dual-action, sustainable soil amendment.

  1. Fertilizer: It provides gentle, slow-release NPK nutrients for plant growth.

  2. Pest Defense: It contains high levels of Chitin, which plants sense, triggering their natural immune response to help protect them from soil-borne pests.
