Regarding mitescides, I consume the honey from my hives. So I and Lil John and others, avoid any chemical that is not naturally occurring in Honey. Of the 3 mite treatments that you mentioned, oxalic acid is the only natural component of honey, and broccoli, and spinach and a lot of vegetables.
If you do not plan to consume your honey, then you have many options. Keep in mind the words of M Bush, Acebird and others: if you treat then you are creating or maintaining honey bees that will be dependent on future treatments,,,,,not Bush exact words but similar.
