Randy "We notice these days that our best honey producers often crash
pretty hard
a couple of months after the flow"
I've had hives since the late 60's and never saw late season best hive
collapses until Varroa. First I saw was a hive that had produced 5 supers
of comb honey. A month after the last super was removed it was empty!
I've always figured the hives with the largest populations of bees also
have the largest populations of Varroa and before I started early
treatments I suspected a point was reached where 70%-80% of worker larvae
was infected. Hive collaspe followed shortly thereafter.
For the second consecutive year I have treated in January with Oxalic, May
and June with thymol, and August with formic. Seems to be preventing hive
collaspe, but I no longer have hives capable of producing 5 supers of comb
honey.
