  Get off the mast and save those bee if you can!

"If you can" needs to bee looked at. Buzz gives good advice as do all which
have posted so far.

The reality of Yoon's situation:

 Test each hive. If over threshold save your time and money as they are
going to perish. Been there done that!

If the hive is under threshold you can treat but if close to threshold only
a 98% control like "Checkmite" will clean up the varroa.
                                   *and*
The hive will be short on young perfect bees to winter on (very important in
cold weather areas)

Either move all the hives over threshold to a remote area to die to keep
down reinfestation or put those hives out of their misery.

I would call your Oklahoma bee inspector for help!

Sorry to hear of your problems Yoon and wish you the best luck with whatever
course of action you decide to take!

Bob
