How to Raise Black Soldier Fly Larvae at Home for Composting and Animal Feed
Raising your own black soldier fly larvae (Hermetia illucens) is one of the most practical and eco-friendly ways to manage kitchen waste while also producing high-value protein for your reptiles or chickens. With minimal space and simple tools, nearly anyone can start a BSFL colony that helps close the loop between food waste and animal nutrition.
Why Raise Your Own BSFL?
Commercial BSFL can be a great convenience, but raising your own offers additional benefits:
-
Eliminates kitchen food waste in a sustainable way
-
Reduces feed costs for chickens and reptiles
-
Produces compost (frass) that enriches soil
-
Allows full control over larval diet and cleanliness
-
Creates a renewable, long-term source of feeder insects
Looking to get started? You can purchase healthy, clean starter BSFL colonies directly from us, ideal for beginning your own bin with strong genetics and high survivability.
What You'll Need
1. A Breeding Bin: Use a plastic tote or custom bin with good airflow and drainage. BSFL thrive in warm, dark, and humid conditions, but airflow is critical to prevent mold and rot. Drill small vent holes to allow wild black soldier flies in your area to access the bin and lay eggs naturally.
2. Egg-Laying Zones: Black soldier fly adults prefer to lay eggs in corrugated cardboard or pieces of wood placed just above the feeding area. Keep these areas dry and out of direct contact with the food waste to prevent egg rot.
3. Starter Colony or Eggs: You can purchase BSFL from reputable suppliers (including us). Once your first batch matures, they’ll produce future generations if given space to pupate.
4. Food Waste: Feed them non-greasy kitchen scraps like fruit peels, grains, and veggie trimmings. Avoid meat, dairy, or anything mold-prone early on.
5. Moist Substrate (Optional): Some people use coconut coir, peat moss, or cardboard bedding to help retain moisture and control odor.
How It Works
BSFL consume large amounts of food waste and grow rapidly over 10–14 days. When they’re mature, they naturally self-harvest by climbing out of the bin (especially if you use a ramp design). These large, nutrient-rich prepupae can then be fed live or frozen for later use.
The remaining residue, called frass, is an excellent soil amendment packed with nitrogen and beneficial microbes—perfect for gardening or landscaping.
How to Feed the Bin: Add food scraps daily or every few days in small amounts, enough for the larvae to consume within 24–48 hours. Spread scraps in a thin layer to prevent anaerobic rot and odors. A simple rule is: feed enough to keep them growing, but not so much that the bin smells or overheats.
Feeding to Animals
Once your larvae are mature, simply rinse them if needed and offer them directly to your chickens or reptiles. Chickens will readily chase and eat live larvae. Reptiles may prefer being tong-fed or offered in a shallow dish.
BSFL are rich in:
-
Protein (~40%)
-
Fat (~30%)
-
Calcium (~2%)
This makes them ideal for supplementing your animals’ diets without needing to dust with calcium powders.
Tips for Success
-
Keep temperatures between 75–90°F for optimal growth
-
Don’t overfeed or allow standing water
-
Use a ramp system for auto-harvesting
-
Introduce pupae to a separate bin with dry soil to encourage adult fly emergence
-
Add cardboard “egg traps” above the food layer for egg-laying
-
Place your bin in a shaded outdoor area or greenhouse to attract wild black soldier flies (if you're not breeding indoors)
Final Thoughts
Whether you're raising reptiles, chickens, or simply looking for a smarter way to handle food waste, growing your own black soldier fly larvae is a practical and sustainable solution. You’ll reduce your carbon footprint, create valuable compost, and provide your animals with a superior source of nutrition—all from your own home.
