Now is the time to finish up with Oxalic Acid if you haven't done it yet. The weather over the next few days is ok for applying Oxalic Acid. Beekeepers that need to apply the dribble method, should have temperatures at about forty degrees at the time of treatment.
As we get into later next week the weather starts cooling off into the 30's for daily high temperatures, and the window for the dribble method will be closing.
The vaporizer is a little more forgiving on temperatures, meaning that a hive can be vaporized when it is in the high 30's and the high forties at the time of treatment. The nice thing about the vaporizer is that the hive does not have to be opened. But, the entrance has to be open to slip in the vaporizer.
Anytime after the Oxalic Acid treatments, winter covers can be put on the hives.
