How would one apply oxalic acid to treat verroa mites? I have read about this method but do not recall the specifics involved.
Metdod is very easy. It must be done during winter when bees do not have brood.
If you have mites much, you can take first brood off and after that you give oxalic acid.
You prepare the solution and spray it with vaccination sprayer (large needle) in the gap of frames.
*********
Hive must be without broods. If you have palm size brood area, it may contain 20% of hives mites. (But to do is better than for nothing.)
Take 7,5 gr oxalic acetic powder into 1 dl warm water.
Take 100 gr sugar and dilute it in the solution.
(Euro coin is just 7,5 g. You can weight your coin and you can use as weight. Own balance is easy to do. Our coin weights are in internet.)
This 1,6 dl volume is enough for 3-5 hives, depending of the amount of bees .
Drop 4 ml solution in the middle of frames, which is 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.
Do not give for 2 box hive more than 50 ml.
Weather can be cold, so bees are in the winter ball.
DON'T GIVE TWICE HANDLING. It is harmfull.
Beekeepers just chatted, what is the way, oxalic acid works. They do know but it works.
From Danmark you will get the same formula.
