Oxalic acid vapor treatment - 12/3/20

 What a sight I was with the respirator mask and full bee outfit but I figured I would need all my protective gear since this was my first time doing Oxalic acid treatment this way.  In the past, I have soaked paper towels with glycerin and Oxalic and laid them over the bottom deep.  But it's too late for that now since I have already have covered it for the winter.

It did seem to go smoothly once I had everything out by the hive.  I did it all as instructed.

  1. Remove entrance reducer and mouse guard
  2. Add 1/2 tsp. Oxalic acid in wand
  3. connect one side of wand cable to battery
  4. slip wand into bottom board of hive
  5. connect other side of wand cable to battery
  6. set timer for 2 minutes 30 seconds
  7. Remove cable from battery and wait another 2 minutes
  8. Remove wand from hive and close it up again
  9. Wait 10 minutes
  10. Return entrance reducer and mouse guard (Note, I had to wait until bees calmed down before putting mouse guard back)

So it's done.  One thing I wonder about is that my wand didn't sizzle when I put it into the bucket of water.   Not sure if I got the amount of vapor I needed or not.  I'll need to check on that with some folks.d

Update 12/4 - The first time failed.  The wand didn't ever heat up so it was a wasted treatment.

The battery didn't have enough juice so I recharged it which took hours (and shouldn't have imo).  Then I performed the entire treatment again today.  It also failed.  

It failed even after I watched the Oxalic heat up in the wand before inserting into the hive.  But it must have heated only enough to melt the Oxalic but not enough to make it a vapor.  Now the battery isn't charged enough to charge the fence so I ordered a new battery to pick up tomorrow. Hope no bear comes through tonight!

I'll take a few days before trying to do this again to the bees. It's such a disturbance each time.
