This will be the last time this blog will talk about varroa control in 2019. By this time you should know that good varroa control is critical to good winter survival.
Here is a link with two videos about using oxalic acid in late October. Personally, I would not use utilize oxalic acid dribble this late in the year since the cold oxalic acid/water solution could chill the bees. Since I had seen brood in early October I plan my last treatment to be in early November.
