Screened Inner Cover/Dead Bees
Newbie. First year.
I've converted all of my inner covers to full screen. We're in Georgia and it stays very hot in summer. I'll switch back when weather cools off. Meanwhile, I get various critters like roaches, wax moths, SHB and honey bees on top of the screen. Last inspection revealed a large number of dead bees (about 50) on top of a thriving colony. Can't say for sure, but I don't think they were mine. I have a diverse blend of bees (Jennifer Berry's Nucs) that lean to dark colors and the dead ones on the screen looked all very light.
I'm wondering about attempted robbery (they can't get past the screen) vs. my own girls getting confused about the entrance location because they can smell their queen's pheromones more coming out the top. Or whatever. Any thoughts?
