Most UK bees carry a little brood in normal Winters but the last one and now this one thus far must make OA treatment more efficient ?.Last Winter could be the reason why reduced varroa loadings were reported?Well being very mindful of John's comments ...... it has been my 'customary practice' to administer oxalic for the girls and sloe gin for me at some point over the Christmas holidays
On a more serious note, any time over the winter period when they are broodless does the job, so in answer to louise, if it was still -15'C over the Xmas break (as it is today in Yorks again today) then I'd delay and wait for at least +ve temperatures. In reality we have a comfortable 2 month + window to administer - Jan & Feb. R
What a wonderful idea!! I might volunteer to do the teaching apiary as well as my lot. I might find others doing the same...........we could have without anybody's outlaws.i thought that it was traditional to use oxalic treatment as an excuse to escape family for a while on Boxing day.
One of the members of Blackburn beeleepers lives just outside of KeighleyJW are you trying to entice me over the sacred border? On the map of England I bought at a York newsagent it shows the pennines very clearly, beyond that it just says 'here there be dragons'
Hoof hoovesThe gentleman bee bandit and purveyor of bee equipment told me that it was traditional to give the bees a pattie of Nectrarpol or similar for Christmas and I believed him in my first year. I felt very excited going out and putting them in the rooves of the hives on Christmas Day.
