In previous years, each of my inner covers had only one small center hole. And that was covered over with rigid foam insulation. Silly me, the moisture had no place to go but back into the hive and (shudder) onto the bees. Black mold was evident on wooden surfaces. Not good. Not good at all!
|Inner covers now have five screened vent openings.|
|Wood shavings filled vent box is gusseted to the hive body.|
|Assembled winter moisture control system.|
Soon, I'll wrap each hive with foil bubble insulation, but you can be sure I'll be careful not to cover any of those all important vents! From all of this, do you get the feeling that beekeeping is some sort of an obsession/addiction? Guilty as charged!
