I've been doing some research on the BSF stuffs for a bit, and was considering even buying (or making) one of those bio thingies that help to breed them efficiently enough to use as feed for chickens, etc, as well as taking care of compost.
This spring I built me a keyhole garden, with the compost basket in the middle and have been steadily tossing all waste in there. I planted sweet potatoes (which, grew like a charm, but, never produced tubers, I think my soil was too compacted, will fix that for next spring's planting)
Oddly, despite copious amounts of compost, I could never fill the basket...I'd assumed that I'd fill it, then, switch to my compost pile, and then back.. but... no!
So, a couple of weeks ago, I went to push aside the vines and check yet another time to see if there were tubers, before ripping the vines out to prepare for fall plantings... but..
Under the vines, I saw bazillions of black larvae... (ok, actually, really really a lot...) Initially squicked, I looked closer, and realized, Black Soldier Fly larvae! YAY!
I can't fill up the basket, because it is being consumed faster than I can place it in there. AND, I notice that the vines closest to the basket where twice as large as the vines at the edges of the garden.
And, bonus! While initially, there had been ('regular') flies around the compost basket, I had failed to notice that for the last few months, there had been none..
Now, if only I could find a way to capture the larvae to feed my ducks.... any ideas?
Here is my home made, inexpensive, better for the arthritic back, keyhole garden:
