Hi All,
 
  I have been using essential oil mix for over a year.They are also being
tested at Ohio State at the U level.
 It has worked for me.No apistan used last year , except for checking for
Varroa on a few hives.
  I will have a better idea on how the fall treatment worked , when I get
into my hives after the rain stops.Bee flight a week ago looked good. That
means very little , when it comes to Varroa.I have over 100 hives at home
to check. I'm at a 5-6% loss right now. The moisture level in some of the
hives has caused problems.I did not have moisture excapes on all of the
hives.
 Before we think that, this is the fix. We need more hard data than just
observation.You can kill your bees with essential oils.Egg laying of the
queen is being checked and more.
 We need more research. I will say that you can look at some of last years
ABJ's and see what they did with essential oils.There are different oils
that have been tried.They are not all the same. So you can get into
trouble in a rush.The best thing to do is wait for the papers to come out.
 Vaporization is complex and varried to the enviornment.We are talking
about a few drops to the quart then less that a ml per hive.
 It is still to early to get excited about.
 My oldest son recieved his degree in Chemistry from the U of Wash last
june and used some input from him. I would not go off like a loose cannon.
Good science takes time.
