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
