I guess I have worked for too many lawyers... And it seems that some here have interpret the law in a unbending fashion which is not how things work in the real world.  The basic rule you should apply when it come to interpreting the law.... is 1) there is THE LAW and 2) there is the implementation of the law (or as is most common NOT).  Which is to say there are numerous laws on the books and some are enforced and some are not... Some laws (like that which applies to oxalic) has no one to even enforce the law.  When I have a question about such matters as this..... I typically ask the head of the Texas Apiary Inspection Service to see what they do and what they think.  Even if I went against their advice there is really no one to enforce the law.

I do treat the bees at the TAMU bee lab with oxalic.  It is so cheap I even play around with dribble, slow release towels and thick cardboard. Like many varroa treatments effectiveness is not the same across all types of application and each one's effectiveness will with proper (not so proper) timing.  It seems to work best in the bloodless state.

I would recommend folks NOT use the oxalic which is sold as wood bleach in lumber supply stores.... < several reasons for this 1) you are uncertain to all the other things added to the mix and 2) mixing stuff up in large batches can pose problems in terms of equal distribution of the various things added to the mix.

You do want to buy the right form of oxalic.

I do like OAV both as a winter treatment (per label) and as an emergency knock down (somewhat off label) when mite counts are above threshold and temperatures are too high for other treatments.  I do want to play with a couple of hives by using screened bottom boards, doing regular sticky boards, using OAV as an emergency 1 time knock down if needed, and follow up sticky boards to see how effective this routine is.  I have used the 1 time knockdown in summer a couple of times with good results, but that may have been luck or chance.  If I do OAV when real honey is in the top super, I chase the bees out of it with Bee Quick and a fume pad, put a piece of plywood between the honey super and brood and do the OAV.  Once all has cooled down, I remove the plywood and reunite the honey with the brood.   I don't use the shop towel OA method.  I'll wait to see the results of testing and if effective, a good reasonably safe method of making and applying them.

Late Fall after the winter bees have been born is not best time to think about mite control imho but, this is when the label on Brushy Mt says to treat for mites. So when the winter bees that have been weakened by the mites don’t survive the winter and you used the product as directed what’s up with that. Remember to test early treat as needed and post test to know if it was effective enough with something.
