Porter bee escapes

[Thymallus]

If you stack your supers higgly piggly when inspecting a colony , drones can enter them and end up above the QX .

Then don't stack them higgly piggly.
I can understand when demareed or no excluder used.
But I can't see the number of possible drones entering supers in a short inspection time having much effect on rhombus clearer's. I reckon there is plenty of room for a drone to get through a rhombus. They are not as "tight" as porters.
What has caused a problem for me this season has been a number of dead bees blocking them. I think the high temps and then isolating the supers has meant the bees were not able to regulate the internal temperatures well here. I had a couple, early doors, where this happened,so I vented the supers whilst clearing through rhombus escapes (the beauty of Abelo poly crownboards) . Still didn't work as efficiently as usual. Due, I think, to the high temperatures we had this year.
