Post Harvesting waste
What is the best manner for harvesting the BSFL's solid waste? With red worms I've had success putting a wire screen with holes in it on top of the compost and putting some new food on top so they migrate to it slowly. Would this method work with BSFL?

Best bet is to quit feeding the harvest-ready bin and start a second one. After a month or so, most of the larvae will have exited the original bin. At that point, just shovel out the residue and restart the old bin with a new colony.

Worms live and reproduce for a long time in a worm bin so continuous casting harvest makes sense, but BSF go from eggs to pupating larvae crawl off in a month or less and they are easy to re-introduce, so no need to maintain a "continuous harvest" situation like you might with worm castings. Think modular and batch process rather than continuous harvest of residue like you would with worms. It's way easier and much less effort.

I've tried stackable bins in a process similar to what you describe. My opinion is it was not worth the effort. If you live in a climate where you have BSF breeding year round, the batch system is ideal because you can harvest the residue whenever you want. If you are in a "summer only" breeding area, the batch system is still ideal! Just harvest in the fall and re-start your colony in the spring. Think
modular" with BSF and it will simplify their husbandry! :)

If you stop feeding the container you want to harvest waste out of, will the small larvae not ready to migrate out that are still in there die?

Maybe, or maybe not. But 90 percent will be in the top few inches of substrate. So just scoop the top few inches off and use it to seed your new bin and the problem is solved.
