Hi John.
    In over 1 1/2 years of testing with MO, I find that mineral oil is effective
against both types of bee mites, Varroa and tracheal mites.
        Although I have not  performed tests with vegetable oil, I would venture
to guess that the mechanism of action of vegetable oil is similar as with mineral
oil. However, mineral how has several advantages over vegetable oil as I
explained in my original release about my work.  Have you obtained copies of the
files that I posted to Bee-L?
In them, you might find answers to a common questions that many people are asking
themselves about the efficacy and other things about mineral oil.
Please do not hesitate to contact me if you have questions or comments.  I'll
always be here to reply and try to help.
Best regards.
