Use the magnifying glass at the upper right to search the Forum. Lots of great suggestions. This is the official word from Flow on what to do:
You shouldn’t lose the hive just because they aren’t using the super. If you have 2 full boxes, they should overwinter fine. The nectar flow is probably mostly done for the year now, so I would take the super off and try again next year, coating the frames with wax, or rubbing some burr comb on them.
