I still keep most of my hives is the shade where they have been for years and years. I catch swarms and sometimes make nucs on my back porch which is in full sun. I know when I pop tops, whether sun or shade, there are them beetles running over. I do not believe they are as bad now as they were in the past. I think either bees are dealing with them better, or other pests are now affecting the beetles. Maybe I am just keeping stronger hives with less open space in the hives as before.
