Dear Friends:
I received a question regarding my earlier post on this subject.  I have
decided to post my answer to the general list thinking that perhaps
others may have similar doubts.
My intention was/is to state that:  After one year using FOOD GRADE
MINERAL  OIL for the treatment of bee mites,  I continue to observe that
mineral oil is effective for the treatment of  Varroa bee mites. And
yes, I have been using the same bee equipment.  Nothing has change in my
procedure, except for a slight increment in mineral oil.  And yes, Food
Grade Mineral Oil has continued to be observed as non
toxic to honey bees unless bees happen to become soaked by the oil (just
like I explained originally).  If I may add, judging from the state of
the frames at this time, I think that those of you who continue to use
the mineral oil procedure will agree that an additional bonus is in the
offing.  It is my opinion that the oil will contribute to the
preservation of the frames.
Please do not hesitate to continue sending me your questions and your
input regarding your observations.
Best regards.
Dr. Rodriguez
