When it comes to an efficient compost organism the BSFL are about the most efficient at eating/chewing 99% of what goes into the compost. We have instructions below available to build your own larva bin or you can get the “EZ BSF Larva Lab” a new product on our website that we designed. This is specifically made for feeding/raising/harvesting the larvae. The full lifecycle of the black soldier fly can be as little as 5 weeks and as long as 8 months (depending on temperature and food availability).
