Is Black Soldier Fly Farming Profitable in Kenya?

Are you searching for a cheaper and sustainable source for your fish, pig or chicken? Black Soldier Fly (BSF) farming is emerging as the best solution for small scale farmers in Kenya. These tiny insects are nature’s solution for recycling organic waste into high-value protein for animals. The flies will eat organic waste into high-quality protein feed and organic fertiliser. It will help you to address key agricultural challenges such as high feed costs and poor waste management.

But how can you get started with BSF insect farming? In this guide, you will learn the best step-by-step tips on how to launch and run your BSF farm.

What is Black Soldier Fly Farming?

BSF farming involves rearing the larvae of the Hermetia illucens fly. Unlike houseflies, BSFs are not pests—they don’t spread diseases or bite. Their larvae thrive on organic waste, turning it into protein-rich feed and nutrient-packed fertilizer.

Benefits of Black Soldier Fly Farming in Kenya

Farmers are adopting BSF farming for numerous reasons:

• Cheap Animal Feed: Larvae contain 42-45% protein and 28-35% fat. Makes BSF a cost-effective alternative to traditional feeds like fishmeal and soya. Incorporating BSF into feed rations significantly lowers feed expenses for poultry, fish, and pig farmers. Using BSF larvae for animal feed can cut your livestock feed costs by up to 28%.
• Clean Waste Management: BSF convert kitchen scraps, manure, and agricultural waste into valuable biomass. It reduces greenhouse gas emissions and promotes waste recycling.
• Organic Fertilizers: The residue left after larvae feed (known as frass) is an excellent organic fertiliser that enhances soil fertility and crop yields.
• Income and Job Creation: Farmers, youth and women can invest in the business and can sell larvae, frass, or even breeding stock to other farmers, and other products locally and internationally

How to Start BSF Farming in Kenya

Are you wondering how you can turn waste into wealth? to succeed in BSF farming, Start small, learn the ropes, and scale up as you gain confidence. Whether you’re feeding your livestock or selling BSF products, this practice promises financial and environmental rewards. Below are our 5 suggested steps for small-scale and large-scale BSF farmers alike:

1. Secure a Reliable Supply of BSF Eggs or Larvae

To begin BSF farming, you need a reliable supply of high-quality eggs or larvae. Organizations like ICIPE or trusted local hatcheries are excellent sources. For beginners, start small with 5 grams of eggs, which can produce around 1,500–2,000 larvae. These larvae will consume approximately 1.5–2 kg of organic waste daily as they grow. The cost of BSF eggs typically ranges between KES 2,000 and KES 4,000 per gram, making the initial investment manageable. Starting small helps you learn the process before scaling up.

2. Create a Simple Farming Setup

You don’t need expensive infrastructure to raise BSF larvae. A basic setup can be built using locally available materials like plastic trays, netting, and shaded structures. For instance, one tray measuring 1 meter by 0.5 meters can hold 1,000–2,000 larvae, process 10–15 kg of organic waste daily, and yield 2–3 kg of mature larvae weekly. Building such a setup costs as little as KES 5,000–10,000 depending on materials, and this system can be scaled up over time to increase production.

3. Source Organic Waste

BSF larvae thrive on organic waste, which is readily available from markets, restaurants, or your farm. For every kilogram of larvae, you’ll need approximately 2–3 kg of organic waste per day. For example, if you collect 30 kg of waste daily, you can sustain a farming unit with 10,000 larvae, which will convert the waste into 7–10 kg of mature larvae weekly. This process not only reduces waste but also ensures a consistent supply of nutritious feed or a sellable product.

4. Monitor the Environment

BSF larvae thrive under specific environmental conditions: temperatures between 27–30°C and humidity levels of 60–70%. These conditions are naturally available in many parts of Kenya, but simple tools like thermometers and hygrometers help you maintain them. Under optimal conditions, 1,000 larvae can consume 10–15 kg of organic waste and grow to 5–8 grams each within 10–14 days. Monitoring these factors ensures maximum productivity and waste conversion.

5. Harvest and Process the Larvae

Larvae are ready for harvest when they turn dark in color, indicating peak nutrition. At this stage, every kilogram of organic waste typically produces 250–300 grams of fresh larvae. After drying (sun-drying or light roasting), this reduces to about 100–150 grams of dried larvae, which can be stored for months or sold. For example:

• If you process 30 kg of waste daily, you can expect 9–10 kg of fresh larvae weekly, reducing to 4–5 kg of dried larvae.
• With dried BSF larvae retailing at KES 150–200 per kg, this setup could earn you KES 600–1,000 weekly.
• Scaling up to process 100 kg of waste daily could generate KES 3,000–5,000 weekly, depending on market prices.

Organizations like ICIPE or local agricultural groups also provide training and technical support, ensuring you get the most out of your BSF farming venture. Starting small and growing step by step ensures both profitability and sustainability.

Where to Sell BSF Products in Kenya?

You can market various BSF products to some ready buyers across Kenya and beyond. Key buyers include:

• Poultry and Fish Farmers: They need affordable, high-protein feed to reduce reliance on expensive fishmeal.
• Crop Farmers: BSF frass is gaining popularity as a chemical-free fertiliser for sustainable farming.
• Export Markets: With global demand for insect-based proteins on the rise, BSF farmers are tapping into lucrative international markets.

Wondering what are the different BSF products you can sell? The major BSF products are diverse and growing. It includes:

• Live larvae: For animal feed.
• Dried larvae: Processed into feed meal.
• Frass: As a soil fertilizer.
• Chitin and chitosan: For food packaging and medical uses. *
• Bioplastics: For sustainable packaging.
• Insect oil: As an additive to animal feed and cosmetic soaps.

Practical Tips from Kenyan Farmers

Kenyan farmers pioneering BSF farming have shared these actionable tips:

• Network Locally: Collaborate with other farmers in your area to secure waste sources and create a stable market for your products.
• Use Family Labor: Engage family members in feeding and harvesting activities to keep labor costs low.
• Plan for Odor Control: Locate your farm downwind and away from residential areas. Add effective microorganisms (EM) to the substrate to reduce smells.
• Diversify Your Products: Sell fresh or dried larvae, organic fertiliser, and even larvae oil for multiple income streams.

Why Now is the Time to Start BSF Farming

Government support and partnerships with organisations like ACIAR and ICIPE are creating a fertile ground for BSF farming to thrive. Training programs and access to quality BSF eggs are becoming more accessible, empowering more Kenyan farmers to join this sustainable movement.
