Hive mat needed with crown board?

Pete, Natasha is in the hills of Perth:

@anon20442494 , most people block up the hole to stop the bees from building in the roof space. Given Perth can get hot, the bees will need ventilation. The alternative then is to mesh up the hole and let the bees dictate how much ventilation they need.

Given that you have a small colony at the moment, a hive mat wouldn’t hurt. A piece of old lino or 0.5mm transparent vinyl from Clark Rubber would suffice. Make sure there is gaps at the periphery to allow adequate ventilation.

Welcome to the forum. There’s a Perth thread here and you’ll be able to work out who’s near you:
