How will I know when my nest box is being used by bees?

Great question! These bees are rather shy, so you will need to be very observant and patient if you want to catch a bee in the act of nest-building. You are more likely to see the cardboard tubes being filled with the bees’ chosen nesting substrate. This is most commonly leaves, soil, or tree sap. You can see a few examples of this in an old blog post here. The bees build their nests starting at the back, so if you see a cardboard tube capped like this, that means the bee has likely filled the whole tube with eggs and pollen!
