When do I use Oxalic Acid Dribble Method. I have been told not to when eggs and larva are present, just do the top super, told to only do the bottom one. When and how, please.

Oxalic trickle kills larvae and only kills varroa on adult bees. It is used when hive is brood less ( here that is November December). It should not be used when supers are on the hive as it contaminates honey. Looks like you have a bit of reading up on varroa to do

You can also do it when you catch a swarm

The reason not to do it when there is brood present is that the majority of the mites are in the cells of the sealed brood. I have dribbled oxalic in the past when just eggs and unsealed larvae present and found no evidence in my colonies of any death of larvae whatso ever.
