Good Morning Everyone,
In my chat room this morning, a gentleman had a very good question for me,
I'm only a beekeeping quide, I am not an expert and I now better than to
answer questions like this, so I'm asking for your expert opinions. I asked
him to send me a note. Any help as to an answer would be most appreicated.

On a wildlife center on Grizzley island (35 miles NE of san Francisco)
we have a wild hive in an Eucalyptus tree which has existed for eight or
nine years.  We often use the hive as a demonstration for school
children, explaining the function of the European honey bee.
These bees are always readily apparent during the flowering season, but
a serious decline in the population of the hive has led me to discover
the presence of the Varroa Jacobsoni mite.
I would like to know if there is a way to disinfect the hive and restore
it to health?  The hive itself is well hidden inside a hollow of the
tree and the entrances are small, prohibiting access to the interior of
the hive. I would appreciate some advice on how to proceed.
Thanks
Art
