Well your first job would be to assess the hive.
How was the honey production?
How is the brood production?
Is the brood healthy?
Then-
what are your mite counts... drop method, alcohol wash, sugar roll method.
If you are doing the alcohol wash or sugar role, you need the bees from the brood frames (w/o the queen)
From there, since your weather has been rubbish, you might consider a pollen patty supplement. I am a firm believer in good nutrition. A diifficult growing season puts stress on plants. Stressed plants = poor pollen proiten.
then you might consider feeding fumagillin B for nosema prevention
and or terrimyacin for AFB prevention
And finally a mite treatment. Now for the mites, when you test them, realize that the mite count doubles in % every three weeks. At four weeks brood damage occurs. At this time of year, anything over 2% will see problems for the wintering bees. What this means is your chance of winter survival decreases.
If you are in a dearth and have pulled your honey, start feeding your hives so they can maintain strength and colony numbers for the winter. In our winters we feed about 5-7 gallons of feed for winter survival. this feed is given in a couple of weeks so they can dry it down and cap it before winter sets in reducing the amount of moisture in the hive for the winter
