>Formic Acid and Thymol are now approved in the US and are good soft alternatives that mites will not become resistant to.

How can you know that? Have you been to the future? Lots of things weren't supposed to happen but did in the end in this world.

The concorde, the space shuttle, the titanic, german high speed rail tragedy, antibiotic resistance, gypsy moths, love bugs, telapia, hygrophilia, africanized honey bee. None of these tragedies and problems were projected to happen, yet they did. The only way for us to counter a problem like varroa is to allow nature to find the balance. Just as resistant strains of mites have reared their heads, so have strains of honey bees been showing resistance to varroa, when both strain and management style allow nature to do her job.
