    Because you said strong vapors I am assuming you used more away or Formica pro?  What was your fall mite treatment?  And when was it?  And did you do a mite count afterwards to know it was effective.

    fall is a big window.   You really need to start mite treatments in mid August, and then the bigger challenge is to keep more levels low until October.  

    My experience is that a really strong hive in the fall can often crash overwinter.  Often the best looking bees in the spring looked somewhat mediocre in the fall.

    How were the local hive losses this year?  I filled out the PNW Survey.  I treated for mites in the fall, took perhaps 10% loss at the time from the strips and the strong vapor, but the hive seemed strong afterward.  I wrapped the hive well and left them all the honey (70 pounds at least).  In Jan it was warm and bees were active so I did an inspection and had a solid layer of dead bees on the bottom board, which was still a screened board but I had a cover beneath it.  I cleaned out the dead bees and switched to a solid board and rewrapped the hive (the top small entrance and the bottom reduced entrance were both freely accessible).  The hive was probably 20%? total of what it was in the fall. After the big snows and colder temps it wasn't until April that I opened the hive on a warmer day and being concerned there was no activity from the hive.  I did a quick inspection only to find no life and still very much honey. The top was full and completely untouched.  I still have the hive intact and will do a more thorough inspection when I can.  Sad to lose this one as the queen was doing such a good job last year with a very tight brood pattern and I thought the hive had a good chance of making it.
