Varroa check in October?

[Pharmacyman]

The calendar on GCBA site recommends a final check for Varroa Mites in October. My hive was virtually with no mites when I checked late August. I'm interested in if you believe an October check is warranted.

October is approx. when drones are kicked out and will be visiting other hives looking for food and shelter. They are the #1 transporter of mites. I would definitely do a mite check about the first frost forecast.
