I also was impressed with how well my unit cleaned up this spring. There were a few issues with the first run of BioPods like the knob and drain jar, but I'm very happy with the quality of the mold and the plastic. After two seasons my unit looks as sturdy as when it was new.

I made a video recently of a load of mature BSF larvae that I collected from two DIY units I threw together about a month ago. Those units are really very crude and inefficient, but they served the purpose.
