I have 3 swarm traps in my backyard in trees.
So far I had 2 occupied, cutout and put into boxes.
Yesterday I was pleasantly surprised to find the 3rd and last swarm trap occupied.
Problem is thought that 15 trees will be chopped up next thursday since they are dead and a genuine fire hazard.
Furthermore our neighbor across the street, whom we exchange produce from our gardens with, suddenly said "I think i have a bee hive in my old chicken coop".
I checked, and she has. So more work to be done soon ;-)
