Will the Robber Screen Work?

This view looks down into the robber screen from the top. You can see that the top allows the bees entry to the hive. At the time I installed the robber screen on Bermuda, the bees were furious and climbed up and down the screen from the outside.







I didn't have the right length of bungee cord, so for the moment, I have rigged it together with three cords and the fence. I'll fix it tomorrow.
When I came home tonight, the bees at Bermuda had for the most part, found their way into the screen and are clustering inside the screen for the night. There are a few on the outside - wonder if they are unable to find the HUGE upper opening!
