Oxalic Acid Vaporizing

[GSF]

When treating with OA vaporizing, is it two or three treatments a week apart? This Sunday is the third Sunday in a row I was going to vaporize. I remembered 2 g per hive, seven days apart, but I don't remember if it's two or three times.

I'm reluctant to vaporize. I haven't used a sticky board but I have several very clean/new oil pans that hasn't really shown any major mite drop post treatments. As a matter of fact the mites I find are hard to find. No DWV or mutants crawling around. I will guess that since every one of my hives has either swarmed, came from a swarm, or raised a new queen, the brood break took care of any potential problems. I do like the evidence that if a SHB/Wax Moth or their larva is in a hive they'll nose dive in the vegetable oil trying to get away.

 Brood breaks do work, plus you always have a fresh queen laying up a storm.
I would think that you need the third time to catch most of the emerging brood in the treatment cycle.

Three times to treat emerging brood. Some folks do four treatments to make sure.

I dont treat swarms their first year.   Second year colonies get hit twice

Thanks folks.

Danno; Would you treat a swarm if you used a frame of comb/brood from another colony to anchor it?

I dont add combs of brood.   I give swarms drawn comb and a frame or two of food if I have it.  If I did add brood I would still have to say no I wouldnt treat.  The brood would have come out of a treated colony and should have a low mite count.  I have found the best way to anchor them is to move them and give them drawn comb.
