So we’re having this heatwave here in Perth of four consecutive days above 40°C starting today.
My hives are in full sun, well insulated, painted white, and have roof vents. I see there are opposing views regarding ventilation so I decided to do a little experiment and see whether I notice any difference.
This experiment is in no way conclusive or scientific because my hives are still building up, and one is rather weak at this stage. But that’s what I have.
Both hive will have the corflute in the upper position, and are single brood boxes with no supers.
This is the weakest of the hives. It will have the entrance reduced to around 10cm, and the crown board blocked, effectively having no top ventilation.
This is a stronger hive, and will have a full entrance, and the hole in the crown board open, with a mesh.
If anyone thinks I’m putting the welfare of the bees in danger, let me know. I will report back with what I observe with bearding - though it would be hard to draw any meaningful conclusion due to the difference in hive strengths. This is unless a bushfire wipes my property off the map, which is a possibility.
What I really want to ask is - in such prolonged hot weather conditions, is there anything you can notice without opening the hives that the bees are in strife, apart from bearding?
