I made two nucs last week, with three frames and a couple frames of bees shaken in. Two days later, the high temperature dropped 20 degrees and started raining (Highs of mid-60s, low 70s). I'm seeing the mustard streaks on the outside of the nucs, three days after I prepared them. No evidence of this on the hives from which these frames were taken.
It's going to take me a few days to receive any treatment that I order, and by then, the highs will be back over 90. Should I go ahead and order treatment or will the higher temperature take care of things?
