I am curious to know how people are perceiving OAV treatments after
overwintering.  I am working in Moldova on a bee project and some of the
beekeepers there tell me they are able to reduce the number of
vaporizations to 1 or 2 after fairly intensive treatments in year 1.  I
began vaporizing last summer and must say I had outstanding overwintering
survival this past winter.

The ProVap is still a pain to use.  The vapor tube clogs in cold weather -
I now carry a propane blow torch to clear it - much better than a wire or
pipe cleaner.  I still think it is dangerous to use - the cap on the vapor
chamber is prone to 'pop' off if the tube is clogged and it sprays hot, wet
acid around, not to mention the toxic vapor.  I hope someone comes up with
a better application technique because the OAV appears to work very well.
