What Is Black Soldier Fly Larvae Powder?
Black Soldier Fly Larvae Powder is a ground insect feed ingredient made from the larvae of Hermetia illucens. The larvae are harvested, cleaned, dried, defatted, milled, and sieved into a brown-yellow powder.
Our standard powder is made from 100% defatted black soldier fly larvae. Removing part of the oil raises the relative protein content. It also makes the powder easier to blend into dry feed, premixes, pellets, and extruded diets.
Common names include:
- BSF larvae powder
- BSFL powder
- Black soldierfly larvae powder
- BSF larvae protein powder
- Black Soldier Fly Larvae Meal
- Defatted BSFL meal
- Dehydrated Black Soldier Fly Larvae
- Whole Dried BSFL
- Insect protein meal
- Hermetia illucens larvae meal
Black soldier fly larvae powder does not have one CAS number. It is a natural biological material, not a single chemical compound.
The standard product is a brown-yellow fine powder with a mild insect meal odor. It is dispersible in water but not fully water-soluble. The protein, minerals, and chitin remain suspended rather than forming a clear solution.
An 80-mesh powder is common for feed premixes and pet nutrition formulas. Coarser or finer milling can be supplied for pellet feed, extrusion, wet diets, and meal toppers.
Nutrient digestibility depends on the animal species, larval stage, rearing substrate, heat treatment, fat level, and chitin content. Buyers should test the finished feed rather than rely on one general inclusion rate.
Unicorns Biotechnology supplies bulk BSFL powder with custom mesh sizes, protein targets, packaging, private labels, and OEM feed blending services.
Defatted BSFL Powder vs Full-Fat BSFL Meal
Defatted BSFL powder contains less oil and a higher relative protein level. It is often selected for protein concentrates, dry premixes, fish feed, poultry feed, and extruded pet food.
Full-fat BSFL meal retains more lauric acid and energy. It may suit high-energy diets, but the added fat affects storage, oxidation control, and finished feed formulation.
The correct grade depends on the target species, protein requirement, fat target, and processing method.
Black Soldier Fly Powder vs Whole Dried Larvae
Powder blends evenly into commercial feed and prepared diets. It is easier to dose, pellet, extrude, or use in a premix.
Whole dried larvae provide visible texture and can stimulate natural feeding behavior. They are often used for chickens, parrots, ornamental fish, reptiles, and zoo animals.
Powder vs Frozen BSF Larvae
Frozen BSFL are fresh larvae that have been sterilized and stored at approximately -18°C. They retain their natural shape, moisture, and feeding appeal.
Frozen larvae are often used as an alternative to live feed for predatory fish, lobsters, crabs, reptiles, and other carnivorous species. They require cold-chain transport and frozen storage.
Natural Nutrients in Black Soldier Fly Larvae Powder
Black soldier fly larvae contain protein, fat, essential amino acids, calcium, phosphorus, potassium, magnesium, vitamins, chitin, and natural peptides. The exact levels change with feed substrate, harvest age, drying method, and defatting process.
Published data show a wide crude protein range of about 21.6% to 65.5% on a dry matter basis. Defatted grades often fall toward the upper end. Reported chitin levels range from about 3.87% to 7.21%, with an average near 6.17%.
BSFL protein contains essential amino acids such as leucine, lysine, valine, threonine, isoleucine, and phenylalanine. The larvae also contain minerals such as calcium, phosphorus, potassium, magnesium, iron, manganese, and zinc.
Lauric acid is one of the main fatty acids in full-fat BSFL. A smaller amount may remain after defatting. Published nutrient values vary widely, so buyers should use a batch COA for feed formulation.
| Natural Component | Role in Animal Feed |
|---|---|
| Crude protein | Supplies nitrogen and amino acids for growth, tissue maintenance, and feed formulation |
| Essential amino acids | Includes leucine, lysine, valine, threonine, isoleucine, and phenylalanine |
| Lauric acid | Provides energy and is a key fatty acid in full-fat BSFL ingredients |
| Calcium and phosphorus | Support mineral balance and normal bone and shell development |
| Chitin | Acts as an insoluble structural fiber and natural insect polysaccharide |
| Natural peptides | May add functional value, but content must be tested before standardization |
| Vitamins and trace minerals | Add micronutrients to poultry, fish, pet, and exotic animal diets |
| Nitrogen, phosphorus, and potassium | Allow lower-grade biomass to be considered for fertilizer formulations |
Black soldier fly larvae do not contain common plant compounds such as soy trypsin inhibitors. However, chitin may reduce protein digestibility at high inclusion levels. Feed trials should confirm the correct dose for each animal.
Antimicrobial peptide content is not a standard purity measure. It should not be promoted at a fixed level unless the batch has been tested with an agreed method.
Black Soldier Fly Larvae Powder Specifications
Unicorns Biotechnology supplies non-GMO Hermetia illucens powder from China. Freeze-dried and spray-dried grades are available. The standard material is antibiotic-free and non-irradiated.
Because this is a whole biological ingredient, purity means 100% declared BSFL material without undeclared carriers. Protein can be measured by Kjeldahl or Dumas testing. Moisture and ash use gravimetric methods. Heavy metals can be tested by ICP-MS or atomic absorption methods.
Standard quality limits include loss on drying of no more than 10.0% and ash of no more than 5.0%. Total heavy metals are limited to 10 ppm. Lead and arsenic are each limited to 2 ppm, cadmium to 1 ppm, and mercury to 0.1 ppm.
Microbiological quality follows current USP-style testing. Total aerobic microbial count is limited to 10,000 CFU/g. Yeast and mould are limited to 100 CFU/g. E. coli must be absent per gram, and Salmonella must be absent in 10 grams.
Mechanical defatting does not require an extraction solvent. Where solvent extraction is requested, the solvent type and residual limit must be agreed before production. Residual solvents can then be tested by gas chromatography.

Benefits of Black Soldier Fly Larvae Meal in Animal Feed
Concentrated Insect Protein
Defatted BSFL meal provides a dense protein source for poultry, aquaculture, pet food, and exotic animal diets. Its amino acid profile includes lysine, leucine, valine, and threonine.
It can reduce reliance on one protein source. It should be balanced with other ingredients to meet the species-specific amino acid target.
Good Feed Palatability
The natural aroma and taste of BSF larvae can improve interest in feed. Whole or frozen larvae can also stimulate natural hunting and feeding behavior.
The fine powder blends into commercial gecko diets, fish feed, poultry feed, and meal toppers without leaving large particles.
Calcium and Mineral Content
BSFL naturally contain calcium, phosphorus, potassium, magnesium, iron, and zinc. These minerals can add value to poultry, fish, reptile, and pet nutrition formulas.
Mineral values vary by batch. Feed manufacturers should use tested calcium and phosphorus values when balancing the final diet.
Lauric Acid and Natural Lipids
Full-fat larvae contain a high share of lauric acid and other fatty acids. Defatted grades retain less oil but provide a higher protein-to-fat ratio.
Buyers can select the fat level based on energy needs, extrusion behavior, oxidation control, and finished feed stability.
Chitin and Natural Peptides
Chitin forms part of the larval outer structure. It acts as an insoluble fiber and may affect gut function, depending on the dose and animal species.
BSFL also contain natural peptides. Their levels vary, so peptide claims should be supported by batch testing.
Partial Replacement of Conventional Feed Proteins
Black soldier fly larvae meal can replace part of the soybean meal or fish meal in some diets. Research results depend on the species, processing method, and inclusion rate.
Studies often report suitable results at low or moderate inclusion. Very high replacement levels may reduce growth or feed use in some poultry diets.
Black Soldier Fly Larvae Powder Manufacturing Process
BSFL powder quality starts with controlled rearing and approved feed substrates. The substrate source affects the protein, fat, minerals, safety, and final regulatory status.
Mature larvae are collected and separated from the rearing material. They are cleaned, washed, and heat-treated to reduce microbial load. The larvae then pass through the selected drying process.
Freeze-drying helps retain heat-sensitive nutrients and produces a porous material. Spray-drying is used after controlled homogenization. Low-temperature dried whole larvae can be processed at temperatures no higher than 60°C when requested.
The dried larvae are mechanically defatted to reduce oil and increase the relative protein level. The remaining meal is milled and passed through an 80-mesh sieve, or another agreed screen size.
The powder then passes through metal detection, sampling, and laboratory testing. Approved batches are packed in moisture-resistant bags or drums and stored in a cool, dry area.
A typical process flow is:
Approved substrate and rearing → Larvae harvesting → Cleaning → Sterilization → Drying → Defatting → Milling → Sieving → Metal detection → Quality testing → Packaging
Applications of Black Soldier Fly Larvae Powder
BSFL powder is mainly used as an animal feed and pet nutrition ingredient. Its protein, amino acids, minerals, fatty acids, and feeding appeal suit several feed categories.
The correct grade depends on the target animal. Defatted powder works well in dry formulations, while whole or frozen larvae suit natural feeding programs.
Poultry, Quail, and Bird Feed
Fish and Aquaculture Feed
Reptile and Exotic Pet Diets
Organic Fertilizer and Crop Nutrient Blends

Frequently Asked Questions (FAQs)
These answers cover the main questions asked by feed manufacturers, aquaculture companies, pet food brands, and ingredient distributors. Batch specifications and import requirements should be confirmed before placing an order.
Frequently Asked Questions (FAQs)
Is Black Soldier Fly Larvae Powder the same as BSFL meal?
The terms are often used for the same ingredient. Powder usually means a finer particle size. Meal may be coarser and can be full-fat or defatted.
Ask the supplier to confirm protein, fat, moisture, ash, chitin, and mesh size. The product name alone does not define the grade.
Is your BSFL powder defatted or full-fat?
Our standard powder is made from defatted black soldier fly larvae. It provides more protein relative to fat and blends well into dry feed.
Full-fat BSFL meal and whole dried larvae can be supplied as separate formats. The requested fat level should be stated in the purchase specification.
What is the protein content of Black Soldier Fly Larvae Powder?
Protein varies with the feed substrate, larval age, drying process, and defatting level. Published values cover a wide range, and defatted meal usually contains more protein than full-fat meal.
The contract should use a minimum crude protein limit. Each shipment should be supported by a batch-specific COA.
Does Black Soldier Fly Larvae Powder have a CAS number?
No single CAS number applies to whole BSFL powder. It is a natural insect-derived feed material containing protein, fat, chitin, minerals, and other nutrients.
CAS numbers are normally used for defined chemicals, not whole biological meals.
Can BSFL meal replace fish meal or soybean meal?
It can replace part of fish meal or soybean meal in many feed formulas. The safe replacement level depends on the animal, amino acid balance, fat, chitin, and processing quality.
Complete replacement is not suitable for every formula. A controlled feeding trial should be completed before large-scale use.
Is this product intended for human supplements?
Our standard Black Soldier Fly Larvae Powder is positioned for animal feed, aquaculture, pet food, reptile diets, and specialty nutrition.
It is not represented as a human food or human dietary supplement unless a separate food-grade specification and legal review are completed.
What is the difference between dried and frozen BSFL?
Dried powder has a lower moisture level and can ship without a frozen cold chain. It is easier to mill, blend, pellet, extrude, and store.
Frozen larvae retain natural moisture and shape. They can improve feeding interest but require storage and transport at approximately -18°C.
How is the wholesale price calculated?
Price depends on crude protein, fat level, drying method, particle size, order volume, packaging, test items, and shipping method.
Freeze-dried material usually costs more than standard dried meal. Frozen BSFL also carries added cold-chain and storage costs.
Can you provide a free sample?
Yes. Evaluation samples are available for protein testing, feed trials, color checks, odor checks, and blending tests.
The sample size and courier charge depend on the destination and product format. Frozen samples require a suitable cold-chain route.
What documents can you provide?
Standard documents can include a product specification, batch COA, SDS or MSDS, non-GMO statement, allergen statement, country of origin, and production flow chart.
Third-party heavy metal, microbiological, amino acid, fatty acid, mineral, and pesticide reports can be arranged when required.
Do you offer OEM and private label services?
Yes. We can produce custom feed blends, meal toppers, premixes, retail packs, and private label products.
Buyers should provide the formula, target animal, pack size, label language, annual volume, and destination market.
Can Black Soldier Fly Larvae Powder be used as fertilizer?
It can supply nitrogen, phosphorus, potassium, and organic matter to fertilizer blends. However, feed-grade powder may not be cost-effective for crop use.
BSF frass and lower-grade insect biomass are normally better choices for organic fertilizer products.
