Oxalic acid liquid treatment for varroa

[Finsky]

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?
