It takes just 30 seconds to give treatment to the hive.
Here is same receipt with pictures from Sweden:
http://www.algonet.se/~beeman/research/oxalic/oxalic-0-nf.htm
Hive must be without brood. If you have palm size brood area, it may contain 20% of hives mites. (But to do is better than for nothing.) Wait that bees are in winterball.
* Take 7,5 gr oxalic acetic powder into 0,1 liter warm water. (One Euro coin is just 7,5 g. )
* Take 100 gr sugar and dilute it in the solution.
* This 1,6 dl volume is enough for 3-5 hives, depending of the amount of bees .
#Give 4 ml fine solution droplets on bees between frames, which are full of bees from edge to edge.
##Do not give for one box hive more than 40 ml, and this only for hive which is totally full of bees.
# If winterball is in lower box, take upper box off and do it.
## Do not give for 2 box hive more than 50 ml.
Weather is good to be cold, so bees are in the winter ball.
###Give treatment only once. Second is harmfull
Beekeepers just chatted, what is the way, oxalic acid works. They do know but it works.
It should be a grid beneath the box, so mites cannot return to bees. In former times they used to keep greased bottom but grid seems to be better.
When I used liquid mites just dropped to the cold bottom board. I have no grid.
The result is really good.

You can find the Oxalic Acid in the paint section of the hardware stores. It's in a little plastic tub and is labeled as wood bleach.
I prefer evaporation:

or make a homemade one with some pipe and heat it with a torch (that's what I did.

I prefer evaporation:
Yes but.... try liquid , at least once. :P It is much more easier. But I do not know if liquid works with thracea mite?
