Black Soldeir Fly Farming Blog

Welcome to the Black Soldier Fly Farming Blog. Here we will keep you up to date on our latest developments with our BSF farming experience. Latest Black Soldier Fly Farming blog post below.

BSF castings from a bin that has been out of action for 6 months. This is pretty much ready to use as compost directly in your garden or use for seedlings

Its spring in Australia and the soldier flies are hatching so I'm starting my Filterbug BSF compost bin.

Here are the videos

Short update to show the WORMS

September is the first month of spring in Australia and I have noticed many soldier fly pupae in my worm bins either raise to the top or escape through the bottom before looking for a comfy place where they can hatch into adult Soldier Flies. Most Soldier Flies coming out of my worm bins are the Australian version of the Black Soldier Fly known as Garden Soldier Flies. I can only tell this if i have seen them after they hatch because their pupae and larvae are identical to the BSF and do the same job as far as we know.

So if you're in Australia now is a good time to get your Black Soldier Fly composting bins built and ready to attract those soldier flies.

Tips attracting the Black Soldier Fly

  • They are easy to attract but not as easy as attracting the common house fly so avoid using meats, and dairies because they will quickly be infested with housefly larvae.
  • Add Heaps of fruit and veggies to your diet and collect the scraps for your BSF composting bin
  • Spoil yourself with filter coffees, use the coffee grounds in your compost bin
  • Put your BSF compost bin in a shady spot and keep it covered but make sure it has access for the soldier flies to entre. keeping it covered will help keep the moisture levels up which is good for composting in general.
  • Don't let your scraps dry up, spay them daily or as often as required to keep them a little wet.
  • have plenty of cardboard cuts or shredded paper directly above or on your scraps for the soldier flies to lay their eggs on.

Bin Selection

The easiest bin to build would be the bucket bin

But if you have a little more time on your hands, a small budget (about $100 for Ply, Gloss, gapfill, wood) and some DIY skills I recommend the Filter Bug. Its off the ground good for your back and access, easy access to collection buckets and excess leachate bucket and has a little storage area to keep your tools.

After ant-proofing you may need to collect the ants left on the wrong side of the ant proofing. collecting them without killing them is easy, just use an old paint brush. It will collect them just like a duster collects dust.

The video above shows a side on view of bsfl digging into soil to get ready for their next stage in development, pupating into adult BSF.

This was the strangest thing. This adult BSF female was faking egg laying. The BSF in this video never did lay any eggs.

So your bin got a little too wet and your black soldier fly larvae harvested themselves dirty. Cleaning them is easy. A hose, piece of fly screen a bucket (with a hole). More on
