At night I went back to retrieve the colony.
This is how I found them:
As you can see there was still a small amount of bees inside the original box:
I sprayed some sugar water on them, scooped them up and dumped them in the wooden box.
Drove home and when i was walking them to their temp place to store them, one of the ladies got me on my thumb ;-)
2 stings when handling thousands of bees is not a bad thing ;-)
