The Upstairs Downstairs Method Replicates the Natural Entrance of the Honey Bee
In the wild, bees enter their colonies through small holes of approximately
25mm diameter which are very easy for them to defend, against wax moth and wasps.
One colony could have several entrances. They build a propolis barrier on the inside if the entrance is exposed, to deflect the wind and for colony defence.
Why do we give bees only a single entrance on the ground floor, like a house, when honey bees have wings?
Honey bees build their colonies from the top down because they can fly, we build houses from the bottom up because we cannot.
A Simple Alternative to the Standard Bottom Entrance
Honey bees using UD intrances
Now used with hives in Africa, Europe, Australia, North America and Asia
