A couple things the bees do with propolis I forgot to mention in the episode: embalming hive intruders, fencing in hive beetles! Bee caulk is amazing. Links collected over at Patreon on the post: The first video I watched on the unexpected winter losses among commercial beekeepers in the US by Dr Humberto Boncristiani of Inside the Hive TV. More on the losses from The Bee Supply channel. GA Master Craftsman Beekeeper Cindy Hodges' excellent presentation on Propolis. Dr. Marla Spivak's presentation on her research on propolis. An interview with her on propolis in general. Ian Steppler on selecting for high propolis bees. Do you have any favorite uses for propolis? Wishing you a wonderful week Patrons and Listeners!

She cares for around a dozen hives in a rural Appalachian highland climate. Colonies are managed for bee health with active selection for vigor, genetic diversity and disease resistance, but without chemical treatments for over a decade. The apiary is self-sustaining (not needing to buy/catch replacement bees since 2010) and produces honey and nucs most every year.
