Inspecting the hive entrance this morning, I noticed a wasp managed to enter the hive. After work, I checked the hive entrance again. There were more activity that in the morning. Several yellow jackets tried to enter, but this time, the guard bees were well awake.
This problem has been reported by other beekeepers during Tuesday's meeting.
Because the activity is much lower now, I decided to reduce the entrance by half, to help the guard bees do their job against wasps & yellow jackets.
There is still pollen coming in, I saw some yellow, orange and grey.
All the drones are gone. The colony appears to be preparing for the winter. With 3 full medium bodies, the colony succeeded in building enough stores.
