Going Back In - September Inspection con't.

Yesterday I went in to get the old funky frame out and to replace the inner cover with a clean one as the one that has been on all season was just sick with moisture and other unidentifiable icky stuff. Well, here's another reason for re-thinking using a queen excluder that I took off four days ago. The bees immediately moved into the upstairs and that old funky frame was as clean as a whistle! Also, the inner cover! I switched them out anyway. I had in some notes that the queen had laid in the bottom of the frames in the hive deep before I placed the queen excluder under it during my spring hive reversal. I think it just got all funky with the uncapped brood being left unattended.
