amount of oxalic acid to use?

[kansas]

So, the frost has thawed here in NE Kansas and my bees are active. 
 
 I performed an OA acid vapor treatment on my 5.4mm cell hive using black steel pipe, propane torch and frame on top of hive w/ glass top (for viewing) w/hole in the side to insert pipe nipple.  Seemed to work fairly well and it didn't take too long for the OA crystals to vaporize in the 1/2" steel cap.  Vaporized once, then refilled cap as I was sure there wasn't enough OA crystals used the first run.

Question: How much OA crystals should be used for a two deep hive?

Kansas, not long ago I made a response in a thread where I typed out the instructions for my Oxalic Acid vapourizer.  I will include a link to this topic for you.

All my colonies (except one) are in two deeps.  When I performed the O.A. vapourizing treatment, I only used what the instructions indicated.  That was 2 scoops (the little scoop that came with the vapourizer) which equated to approximately 2 grams.  That was plenty for the colonies and the mite drop was very efficient.  Even after 2 weeks when I performed the sticky board test to see if there was further mite fall, there was significant numbers.  Hope this helps you out.   Have a great, wonderful day.  Cindi
