Eleven days ago I treated my green hive with Formic acid, at the suggestion of Jennifer Berry......(she actually suggested Formic acid or Apilife Var). When I went back into day, they look great!! Two supers of honey, that I am leaving for the winter.
The 3 hives at the Grebels' are looking good too! I did move a full super from Genesis to blue, and put the half drawn out one onto Genesis. Exodus hive seems to be weakest, but has full super waiting for winter. My fingers are crossed that they will survive the winter.
Good news is that all hives look good......bad news--- no more harvesting of Honey this year!!
