Finally figured a good way to get the bsf larva out of my bin without having to dig around for them. I don't have a biopod so I don't have an automatic collection system. What I do is this... I drink coffee every morning. When I'm done with my coffee I pour the used grinds into a small plastic starter pot. I make sure not to let much of the coffee grounds fall out through the drain holes in the bottom of the pot. Then I just set the pot on the top of the compost in my bsf bin and over it up. The next morning the pot will be absolutely teaming with bsf larva that have crawled up inside the pot. I just dump it out into a bucket and the larva are pretty easy to seperate from coffee grounds as opposed to the compost mess in the bin.
