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.
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.
