When Do Nurse Bee Take Their First Cleansing Flights?

[Steve10]

Just a curiosity question. I've never seen anything written or posted on the subject and a search came up empty. Anyone know or give a good guess on this one?

Studies done in 1922 placed the first cleansing flight in the latter part of the nurse bee period of development. Under average conditions this would be some time between 3 days and 15 days after the bee emerges from the cell.
