Susan here. If you are a bee club member, you already know that PBC has been talking about hive insulation all this past year. How do we with wooden hives get these flimsy-walled things to be good for bees? Some of us can’t afford new hives whenever we learn of new innovations that are healthy for bees, so is there a way for us to “modify?”
We’ve been looking at this issue from the outside of the hive, mostly. There are foam and also bubble insulation wraps available, and all require basically encasing your hive box top to bottom with these panels.
Some of us are adding another layer of wood, tacked to the outside of the hive. we’ve discussed encasing our hives in straw bales, which Jacqueline tried—and discovered it is a great way for growing mushrooms between hive and straw.
Then, in Holland, I saw this: a Warre’ hive with a circular interior, packed with plaster, cork chips, and straw. Wowza! Insulate from the inside, instead and solve more problems than just warmth and cooling!
