I made the emulsified mix last night - no problems in doing it but the smell really hangs about!! Recommend you put the extractor on full blast and keep the windows open! Dispose of any paper towels used to clear up as well!
Thanks for the reassurance Victor - many beekeeper round here are suggesting that other remedies (Apivar life?) are effective when Apistan is not. I would have preferred to use varroa stick which hasn't got the nasties of some of the others, but the infestation was severe
