I have a split in a top bar hive and estimate that I have a few more weeks before I have capped brood. I was not going to do a mite count at that time, but rather proactively do an oxalic acid dribble (I don't have equipment to do a vaporization but could borrow from a fellow beekeeper if I really needed to and if I can find a respirator).

I understand that the dribble method may be more harmful on open brood and to queens, but welcome any feedback as to whether this would still be a reasonable approach? I also have Apivar but would prefer to not use that if the OAD is appropriate.
