This does not make sense from a physics standpoint.  Once mixed with air the density difference from pure air is negligible.  The density difference might cause the formic air mix to settle for a few mm next to the formic source in still air.  But a hive does not have still air.  And at greater distances dilution with surrounding air is going to make the density difference too small to matter.


Dick,   I am not quite following what your trying to say here about the formic vapors?  Do you think they would in fact disperse at a high level even though on a bottom board???

I do know that when you use MAQS,  you will without any doubt  kill the grass in front of the hive,  so those vapors do sink at least a bit.





Frank,  In your note you said it works in the bottom super only,   are you referring to just the standard hive body?  Implying that the vapors wont rise in a larger hive??
