One thing about polystyrene is that it does not breathe at all. I wonder
what kind of entrance4 reducers you use and if you use top ventilation
and/or flight holes.
I know that in Europe, in some regions where polystyrene hives are common,
that beekeepers don't use top entrances.
What are your thoughts? Maybe Mats and P-O and others might comment too.
