I'm planning using an insect fogger with ethanol/oxalic this fall.  

I can't readily find the autoignition point for an azeotropic mixture of ethanol and water, but for pure ethanol, the autoignition point is 363C/685F.  Based on the flash point of the azeotrope, my guess is that the autoignition is similarly elevated.

My guess is that enough thermal energy is absorbed with the state change from liquid to vapor that those temperatures will not be reached with an insect fogger.
