Question:
I was recently on a website (www.beesource.com) and found a lot of
information on using food grade mineral oil for the control of Varroa mites.
Have you any opinions about this?

Reply:
Dr. Eric H. Erickson: It has long been known that many oils are good
insecticides and miticides. In the early 1980s, it was discovered that
cooking oil was effective against tracheal mites. It is believed that the
oils compromise the mite's (and insect's) ability to breathe. We are aware
that some beekeepers are using various oils to control varroa and feel that
they are having success. The problem lies in achieving mite control with out
harming/killing bees. We know of no controlled scientific studies that
provide meaningful information on rate and method of application and, more
specifically, how these issues relate to effective mite control and bee
safety. We do know that the specialized respiratory system of varroa allows
them to float unharmed on their back for long periods of time.
