OK It's mid-October here in W/ Iowa. What do I need to do to winterize my hives(2)?
First you should reduce the hive space for the size of winter cluster. Cluster will about same size as the brood area during late summer. If the brood area has been maximum 5 frames, the hive need only 5-6 frames for winter. Put the the frames into winter space and shake bees from other frames in front of the entrance.
Put an white empty comb against the wall. It the comb is full of pollen like bees use to do, it will get mould easily.
So - white comb-pollen comb, brood combs- pollen comb - and white comb against the wall.
Then feed the hive full sugar syrup 1:2. If combs are not full they will not cap the food.
It the box is full of brood and you cannot feed them, put an empty box over the brood and feed it full to be capped.
