My bees seem to screw everything up. Or is it the beekeeper.?????
Anyhow; Last PM I checked the bees and many were outside the hives. It was 90+ degrees but previousley they didn't cluster outside when that hot. Today I opened the hives and found the ventilated innercover, below the "attic" and cover, was closed with propolis, therefore no ventilation. I have 5 holes in the inner cover, covered with window sceen. I went to the house, drilled 2 inch holes in other inner covers, covered them with screen and put them on the hives. How do I prevent these "dumb" girls from doing this again and how do I clean up the covers they messed up??
