There has been no more news about Varroa for a while.
The best information came from the Uni Florida.
It appears they are leading researchers in our climate range.
Reading a lot of their information ( and watching videos) i have worked out a plan which i feel i can handle considering my age limitation, time and financial cost.
Of course I'm hoping that Varroa will not make it up this way for some years.
Everybody I sell nuc's to is aware of the requiremnet to watch out. I have quite a large mailing list and will keep these beekeepers informed.
