I will fasten a chicken wire behind the entrance so to keep birds away from nesting into the bait hive.
open lock above and closed lock beneath for hive transport so bees can fly out yet can get sufficient air (short distances only)
I have made some propolis tincture and painted a bit of itto all my hives so to add as much of hive smell as possible. Another lure will be wax on the top bars as comb guides and Lemongrass Essential Oil to mimic Nasonov Pheromone. If there are wild swarms out there they will find this hive irresistible ;)
