Robert Darrell commented on the effectiveness of oxalic acid in broodless 
hives. This year I am going to try to use this in the following way:

I will  find the queens in all hives in the spring and put each in a 3 frame 
nucleus box without any sealed brood. I can vaporize oxalic in the nuc boxes 
at that time and get all their  mites. The main colonies I will leave to 
raise their own queens. It takes 13 days till the queen emerges and another 
7 days before she is bred and laying eggs. At this time there should be no 
sealed brood left in the main hives and I can vaporize the oxalic in them at 
that time.

Any comments?

Best regards,

Donald Aitken
