This is my first year as a beek. End of July I harvested two combs of honey. A couple days ago I checked in the hive to see if they had rebuilt the combs. They had and were full of capped honey. They have been attaching comb everywhere in the hive, including the sides and bottom. My concern is that they started to attach to the follower board I keep at the back of the hive and once they do this I won't be able to access the hive anymore without breaking the comb. I want to leave them the honey for the winter so am reluctant to harvest any more, but I also don't want them to continue attaching comb to the back board. What to do??

Thanks for any and all advice!
