Warmer temperatures are moving in for early next week. Last minute feeding can be done if needed.
Too early for Oxalic Acid treatments. Late October is your best bet for proper treatment.
In my opinion I think all beekeepers should be treating with Oxalic Acid. If your hives have been running low mite counts, a treatment of Oxalic Acid in late October will clean up and extra mites. This will keep a colony healthier and will help the colony deal with the rigors of winter.
Entrance reducers should be in right now.
Winter covers can be put on anytime after Nov 1st.
