Black Soldier Fly (BSF) (as otherwise used to produce Natsoil Organic Fertilizer), also known as frass or compost from the larvae of BSF, contains a variety of beneficial microbes that help enhance soil health and promote plant growth. These microbes typically include:

Bacteria: BSF fertilizer is rich in beneficial bacteria such as Bacillus, Pseudomonas, Streptomyces, and Azotobacter. These bacteria help with nutrient cycling, nitrogen fixation, and the breakdown of organic matter.

Fungi: Some beneficial fungi like Trichoderma and Aspergillus may also be present, contributing to decomposing organic materials and enhancing soil structure.

Actinomycetes: These are a group of bacteria that help in decomposing tough organic compounds, producing antibiotics that can suppress harmful pathogens in the soil.

Protozoa: These help control bacterial populations by feeding on them, which helps regulate nutrient cycling and soil health.

Nematodes: Some species of beneficial nematodes may be present, which can help control pests and further contribute to nutrient cycling.

The exact composition of microbes can vary depending on the BSF larvae's diet and the composting conditions.
