New Bee
This for a beginner so lets keep it simple. You are arguing against the advice given by manufacturers of Apistan and Apivar who rely on distribution of the active ingredient and that needs lots of movement by the bees.
The point here that has seemingly been missed is that the thymol treatment should have been started earlier. The beginner should not have waited an extra two weeks until mid-October to take off the thymol tray. If it had come off at the beginning of October there would have been more margin for a check and commencement of a follow-up treatment.
Now we are dependent on luck and if you have seen an unclustered colony at minus 10 degrees C what were doing in the hive and were they unclustered before you went in?
