One of my mason bees checking out a space in the bee condo. She refused to sign the lease and the annual price was free. I include free child care. She still refused.

 Here is a photo of a mason bee checking our a tube. It was April 14, 2020. Many of the bamboo tubes were already filled. So she was inspecting a routed-wood-tray.

She hated it. They want BAMBOO tubes.  I will only provide paper and bamboo tubes for 2021.
