I went with forced vaporization this year so I wouldn't have to split the
boxes on doubles or break the propolis seal on singles.  Most years there
isn't enough time for the bees to fix the seal between the boxes or between
the lid and boxes.  With barrel fed yards there is often a lot of burr comb
between in inner cover and top frames which makes the gaps worth.  With
vaporization, I can treat with a lot less disruption.

I am using the Lega unit.  You load enough OA to do the whole yard and the
dosage is based on time.  My only concern has been trying to establish the
correct dosage.  The vapour escape varies significantly hive to hive
depending on bottom board type, inner cover type, and general equipment fit
up.  Should I be treating the "leakier" hives longer, or is there a safe
average dose?
