This video shows, although it’s hard to spot more than a couple, the distribution of BSFL through the whole pile. I may retake the video as it does not show the healthy population the bin has! Honestly, I think the bins current configuration is now a winner. From the trial and error to date, good drainage, and prevention of filth flies laying into the compost are key ingredients for successful BSFL composting.
This photo is of the second bin with the improved drainage. Some compost from the IBC, filled with variously developed stages of BSFL has been added to the top. I am simply making every effort to expedite the dominance of the BSFL, and guarantee no more filth fly problems. Can’t say the same about labrador retrievers. Notice how the barrier wall is missing? Our lab, ever peckish, decided to feast on some compost overnight, ripping out the barrier. The bin isn’t to moist however, and it seems BSFL that want to crawl off are still finding the collection canister.
All filth flies have finally finished in the first bin, crawling off, and leaving a mess. Muck everywhere, up the sides and outside the bin, as they were able to climb vertically because of the moisture. Visible in this photo is BSFL activity. And the BSFL you see on the surface is about all there is. I shoveled out all this compost and bucketed it into the IBC composter. It was putrid, waterlogged, and only active on the surface.
