I know with the cooler temps it is time to pull all my honey and get the meds on. Labor day was hot and I pulled about 75 supers off. The hot day made the honey robber on fume boards work great. I brought home a very small number of bees.
I will start putting on fumigillan now in syrup and treating for Varroa.
Any colony that didn't produce and seems to be dwindling could possibly have Nosema Cerane. The fumigillan should be able to clear this up. Hopefully the bees have time to recover.
Feeding early is better than feeding late. Feeding promotes brood production. I want the bees to slow the brood rearing as fall deepens and it gets colder. This will save more food for winter.
