I'm asking this in the commercial forum because you folks are highly qualified to give a valid answer. Specifically I am most interested in what EPA approved treatment is most recommended for the late fall broodless period which here is roughly between Thanksgiving and Christmas. It can be cold (freezing overnight at times) at that time here but there are usually ample opportunities to work when the weather is fair and bees are flying with temps in the 60-70s.
I am preparing for a presentation on treatment options aimed mostly at newer beekeepers many of whom may not have treated yet because they are confused by what to use, when and how to use it. I want to encourage them to take this last good opportunity this season to decide and take action.
Thanks for your help, and sorry for the amateur question in your space.
