Since Marion Ellis did his work,

not all that much has happened.
By "not all that much", I mean "absolutely nothing at all".


But we can all take heart in this advice from the EPA:

Which says, in part:

"Oxalic acid is exempt from the requirement 
of a tolerance (or legal residue limit) when 
it is used as an inert ingredient in pesticide 
formulations that are applied to growing or 
harvested crops.  EPA also is regulating oxalic 
acid under its Inerts Strategy."

So one CAN use Oxalic Acid today under the 
regulations that exist if one reads carefuly. 

One applies a 3.5% solution of oxalic acid crystals 
dissolved in 1:1 sugar syrup to make the INERT 
carrier solution, and add a single drop of 
whatever ACTIVE ingredient one has chosen to kill  
mites.  For an ACTIVE ingredient, one might choose 
anything from the fabled Food-Grade Mineral Oil to 
Formic Acid, to the melted wax from one of Dee 
Lusby's magical small cells.  

One can apply the solutions to the top bars holding the 
crop of wax one is growing down in the brood chambers, 
where bees are most enthusiastic about drawing new wax 
quickly. I tend to harvest the 2 oldest frames of wax 
from each brood chamber every spring, so I apply 50ml 
of the solution to the top bars of 2 frames in 
the lowest brood chamber.

It does a WONDERFUL job of repelling the wax moth, and
protecting my spring wax harvest.

That's my story, and I'm sticking to it.  :)
