Dear friends:
      Please bear with me.  I keep thinking about different suggestions
as new mail arrives regarding the use of mineral oil.  This is a term
mostly used in the Americas.  In  Europe (I should have remembered)
mineral oil is known as
paraffin oil.  It is the same thing.  In North America, mineral oil
approved for sale as veterinary medication should be appropriate.
Thanks to those of you who keep providing me with input on this subject
and to those of you whom I know will do in the future.  As beekeepers,
we must stay together in the fight against the terrible plague that bee
mites age getting to be.
Happy beekeeping.
Best regards.
Dr. Rodriguez
