A beehive was in a tree in my backyard for 2 days. Today the beehive & bees are gone. Where did it go? Did the bees just pack up & leave??
Sure they did!
What happens with swarms, they move on looking for a suitable
home, [indoor] like inside walls, hollow trees etc. they have scout bees searching the area,..they tell the rest, hurry up and goo,..smart little buggers!
