Steve E from California, contacted me about setting out mason bees in an almond orchard. He asked me for feedback on his idea of constructing a housing unit for mason bees out of a plastic barrel.
” I brought the two plastic tubs into my garage and took this photo of the 2 containers side by side. You can see that the all-blue barrel is uncut, while the white one has a cut-out door of about 12″ x 16″ bordered by black tape. Within the barrel are stacked cinder blocks. You can make out a roll of cardboard tubes within one cinder block. On top of the cinder blocks is a wood bee block.
