Why the hive evicts its drone bees every fall.

Every fall, worker honey bees throw the colony's males out of the hive to die. If you stand at one of our hive entrances this month you may catch it happening: a worker hauling a bigger, blunt-bodied drone out the front door, with the guards refusing to let him back in. Mating season is over, and the colony has decided he is not worth feeding through winter.

A drone is built for exactly one job. The Mid-Atlantic Apiculture Research and Extension Consortium notes that drones have no stinger, no pollen baskets and no wax glands, and that they have never been observed taking food from flowers. A hive may carry several hundred of them through late spring and summer, because a strong colony wants its genes in the air when a young queen flies out to mate.

That math works in June and falls apart in October. Penn State Extension puts it plainly: drones are evicted in fall because reproductive opportunities have ended for the season and the males are now a drain on the colony's food stores. Every bit of honey a drone eats in November is honey the cluster does not have in February. The workers are not being cruel. They are closing the books.

The hive does not pad its numbers in September, and neither do we.

The eviction is not random either. A 2024 study in Behavioral Ecology and Sociobiology found that workers evaluate drones and evict them selectively, removing immune-challenged and smaller males at higher rates than healthy ones. The drones that did get their one chance never came home anyway. A queen mates in flight with seven to fifteen drones at an altitude above twenty feet, and mating kills each of them on the spot.

We like this fact because it is honest arithmetic done early, while there is still time for it to matter. A hive that tells itself the truth in September is a hive that is still alive in March. We try to run the dealership the same way in Libertyville: a straight number on the window, never over MSRP, nothing quietly added at the end. Come late spring our hives will start raising drones again, and the whole cycle opens back up.
