Talking about leaving supers on, for example Nadiring over winter or even finishing off part filled supers in September, using Apivar for 6-8 weeks is the question. Instructions say not to be used if honey supers are in place due to toxic residue in honey and also in wax. Does this mean waiting until Apivar strips are removed before Nadiring? Presumably any part filled supers should be taken off before Apivar or Apistan is introduced. Then should any over wintered Demareed deeps put on top of the stack not be used for honey either?
