really helpful summary
I put my supers over the crown board with bee escape removed so the bees 'dry' the comb and remove the remaning honey as they take it down to the nest. Wet supers need to be put back like this at dusk as the bees realize there is honey outside the nest area and go outside the hive to look for it.
Once dry - a few days - I then store them in a shed, one above the other with something solid underneath - piece of plywood. The top has some small hole plastic mesh - sold as greenhouse shading to allow ventillation and to keep wax moth out. A queen excluder or two go on the top to keep the mesh in place. Mesh - if available is put between supers to limit the travel of moth if it does get in.
I will treat with Acetic Acid or sulphur strips. Wax moth will munch away at supers as well as brood chambers. Sulphur kills wax month. 80% Acetic acid also works on Nosema. Both need to be treated with care!!
I would be concerned that supers that go into storage 'wet' and are sealed up in plastic will come out mouldy in the Spring. Mice will eat through pallet wrap if the have a mind to.
Last year it was so cold for a long time so I didn't treat the moths. Cold = dead wax moth.
SWMBO would not be too keen on me using the freezer!
