With three variables at play (hive size, treatment dose, and temp), and no
hard and fast rule that I can find on how to adjust for the variables, it
would take me considerable time and energy to get enough experience to feel
comfortable that the treatment I'm giving will have the best mite kill.
While I'm getting that experience, I'm bound to lose hives to high mite
counts on treatments that were less than effective, and lose hives to side
effects of the treatment itself when the formic was too effective.

Unless I'm seeing it incorrectly, I'd rather take my chances with OA Vapor,
Apiguard, Apivar, or the mites themselves during the hot summer months then
Formic.
