So I recommend you follow the OAV instructions for as long, and only as long, a time period as necessary. As you know, you’ll need to seal the hive for the treatment. Just be sure to “unseal” the hive as soon as the treatment is completed. For what it’s worth, I have seen recommendations for a lower ambient temperature limit.
How effective is OAV for mites?
OAV is very effective against phoretic mites. We estimate this “knockdown” eliminates between 30-35 percent of mites in the colony. This assumes between 35-50 percent of mites are phoretic and the single OAV kills between 85-95 percent of the phoretic mites.

What happens to OA when heated?
What happens to Oxalic Acid when heated (vaporized)? When OA reaches 215 degrees (f) the water boils off leaving anhydrous (water free) OA crystals. At 315 degrees the OA crystals start to sublime (go from a solid to a gas). At 372 degrees, OA which has not sublimed decomposes to form formic acid and carbon monoxide.
