Dead bees on the ground after first sharp frost in Kent — normal mortality or something wrong?

Woke up yesterday to our first real frost of the season (-1.5°C) here in Kent. When I walked down to the hives at lunchtime, there were about 60 to 80 dead bees scattered on the grass in front of my two hives, and a dozen more lying motionless on the landing boards. Both hives were treated with Apivar in September and natural mite drop last week was under 1 per day. Stores feel heavy (about 20 kg each). Are these just elderly summer foragers that got caught out by the sudden morning freeze when trying to take cleansing flights, or is a sudden pile of dead bees on day one of freezing weather a sign of a cluster problem inside? First winter panic setting in! 🐝

Completely normal, Priya! Don't panic. A strong autumn colony loses 50-100 old bees a day naturally. In warm weather they fly off and die in the field. When it freezes, they drop near the entrance or get undertakered out onto the porch.

If you see 50-100 on the grass, that's just the undertakers doing housecleaning after a cold night. You only worry if you see thousands piled up blocking the entrance tunnel, or if they have bloated abdomens with brown staining on the front wall.

Agreed. Remember that during October/November the colony population naturally shrinks from ~35,000 summer bees down to ~12,000 winter bees. Those remaining summer foragers have to die somewhere. You are seeing standard senescence.

Phew! Thank you @DevonBees_Em, @PerthshireBees, and @ImkerinLena. I took a deep breath and left them alone. So reassuring to understand the math of the summer bee die-off.
