Why traditional animal farmers should add BSF farming

01 · The model

What is black soldier fly farming?

BSF farming involves rearing larvae of the Hermetia illucens fly on organic waste, including food scraps, manure and crop residues. These larvae grow rapidly, converting low-value biomass into high-protein animal feed, organic fertilizer (frass) and other value-added products.

02 · Benefits

Key benefits for traditional farmers

03 · Feed

Low-cost, high-quality animal feed

BSF larvae are a natural protein source for poultry and pigs, with:

Up to 50% protein and 30% fat content.
A favorable amino acid profile for monogastric animals.
Potential to replace 25–50% of commercial feed or fishmeal.

Result: Lower feed costs and improved self-sufficiency.

04 · Waste

On-farm waste management

BSF larvae can be fed with:

Chicken or pig manure in many developing countries – check your local legislation, many developed countries restrict the use of manure as a larvae substrate or at least restrict the end use of larvae fed with manure.
Kitchen and restaurant scraps or farm leftovers.
Spoiled crops or food industry byproducts, waste potatoes, spent grain etc.

Result: Lower waste disposal costs and reduced odor or disease vectors.

05 · Frass

Organic fertilizer for crop use

BSF farming produces frass, a nutrient-rich byproduct that can be used as:

A natural fertilizer on the farm.
A product for resale to other growers or gardening markets.

Result: Better soil health, circular input loop and additional revenue stream.

06 · Infrastructure

Synergies with existing infrastructure

Animal housing waste can feed larvae.
Chicken coops can be located near BSF units to allow direct feeding.
Pig pens often already have waste collection areas, ideal for BSF input.

Result: Efficient use of space, labor, and resources.

07 · Revenue

Revenue diversification

Beyond internal use, BSF farming allows farmers to:

Sell larvae live, dried, or processed.
Offer frass to local farmers or gardening stores.
Sell BSF eggs or starter kits to other farmers or hobbyists.

Result: Increased farm resilience and new business opportunities.

08 · Environment

Environmental and regulatory benefits

Reduces dependence on soy and fishmeal.
Mitigates greenhouse gas emissions from manure.
Positions the farm as a sustainable, circular operation – increasing its appeal to eco-conscious consumers or grant programs.

Result: Compliance with environmental standards and potential subsidy eligibility.

09 · Chicken and pigs

Why it works best for chicken and pig farmers

Both pigs and poultry are monogastric animals and readily digest insects.
Insects are part of the natural diet of free-range chickens.
Larvae can be fed fresh, dried, or mixed into existing feed.
On-demand harvesting fits into variable feed needs and farm schedules.

10 · Final thoughts

Final Thoughts

Black soldier fly farming is not just for biotech startups or urban insect farms. It’s a practical, profitable and sustainable tool for everyday farmers. For pig and poultry farmers in particular, BSF offers a natural synergy with existing waste streams, feeding routines and infrastructure – helping them reduce costs, generate new income and make their farms more resilient and sustainable.

By embracing insect farming, traditional farmers aren’t abandoning the old ways – they’re future-proofing them.
