It is very good to treat swarms with oxalic acid trickling. You will not regret it.
Against the law? So say many who never drive car with over speed or against red lights.
Oxalic leaves no traces to the hive and no one knows that you have used it. Just wood preserving.

I like your way of thinking Finski! Sugar dusting has not been FDA approved either.
I hope you don't mind if I repost this:
Here is the recipe per Finskis post here:

Recipe
mix 100g sugar + 100 g water + 7,5 g oxalic acid.
This enough for 3 two box hives or 5 one box hives.
Cost is almost nothing.
Buzzbee note
Most inexpensive small kitchen scales measure grams and ounces.Don't overcomplicate it!
And it is called wood bleaching. Everyone needs clean frames.
I don't do drugs so I don't have a gram scale. What is that in English?
7.5 grams equals 0.26 ounce.

But with varroa it is too late. What we have found in Finland is that bees do not stand such mite loads as 20 years ago. Assistant viruses and so on makes more harm than before. '
Biggest losts by varroa is reduced size of winter cluster and slow spring build up and delayed yield

I understand trickling and that broodless is necessary. This makes good sense trickling a new swarm. How about sublimating a swarm once. The results should be equally as good as long as they dont abscond.
Also Ken what was Finskies doseage. I think it is 50ml per seam but I dont remember total per 2 box colony, single deep and 5 frame
.
Yes, that meaure. Measures are mentioned to winter cluster. Bees are tight there.
Swarms in summer are not so dense. I would think that dose is half that of winter cluster.
Idea is that acid syrup makes bees dirty and acid stays long time in bees kin.
If we have one box swarm = 2 kg, 30 ml is enough to the box. Perhaps 25 ml.
It means that 2,5 ml per seam.
If the swarm is big, It occupyes 3 langstroth boxes. I would use max 35 ml = 3,5 ml per seam.
Last Autumn I gove clearly too much to winter cluster. It seemed bad and I gove over bees saw dust which absorbed extra syrup. By the way, that hive is now the best. It has perhaps 15 frames of brood and normal hive has 4-5 frames.
