For generations, many northern beekeepers have been taught that winter colonies need upper ventilation to allow warm, moisture-laden air to escape. But what if that familiar advice is working against the bees? In this episode of Honey Bee Obscura, Dr. Jim Tew welcomes Anne Frey to explain the condensing hive concept and why it has caused Jim to reconsider some long-held wintering practices.

Anne explains that a condensing hive isn't a special piece of equipment. Instead, the concept relies on substantial insulation above the colony while allowing the hive walls to remain cooler. Moisture produced by the bees can then condense on those walls rather than on the ceiling, where water might drip back onto the cluster.

They also discuss eliminating—or greatly reducing—the traditional upper entrance, the role of elevated CO2 in lowering winter metabolism, and why moisture inside the hive isn't automatically harmful. In fact, bees may use condensed water to help consume stored honey.

Anne adds an important practical caution: without an upper exit, dead bees, snow, or ice can block the lower entrance. Her own approach leaves a very small upper opening as insurance.

Jim and Anne close by considering insulating quilts, warmer climates, and whether top insulation might even help colonies during summer heat.

The bee yard is a familiar place during daylight. After midnight on Halloween? That's a different story. For this special episode of Honey Bee Obscura, Dr. Jim Tew reaches back into the archives and invites Jeff Ott to join him once again for a few spooky—and very funny—stories about what happens when beekeepers find themselves working bees after dark.

Jim begins with an encounter in the attic of an old Ohio State farm building. Armed with a questionable flashlight and surrounded by forgotten beekeeping equipment, he discovers that the mysterious shape waiting in the darkness is a fully grown raccoon backed into a corner. The raccoon wins.

Then Jim recalls working alone late at night near an abandoned facility, preparing colonies for apple pollination. Nothing actually happens—which somehow makes the growing feeling that he isn't alone even worse. Eventually, Jim abandons the bee yard entirely, smoker and all.

Finally, there are southern bee yards, rattlesnakes, black widow spiders, watermelon pollination, and Jim's brother mistaking a vibrating phone on his belt for a striking rattlesnake.

No monsters. No ghosts. Just beekeepers, darkness, bad flashlights, overactive imaginations—and a reminder that a familiar bee yard can feel like an entirely different world after midnight.

Happy Halloween!

Plastic is now so common in beekeeping that it's easy to forget there was a time when virtually everything in the bee yard and honey house was made from wood, metal, glass, or cloth. In this episode of Honey Bee Obscura, Dr. Jim Tew looks back at that transition. He remembers glass honey jars, heavy 60-pound storage tins, wired foundation, handmade beeswax queen cups, metal-screen veils, and the equipment that defined beekeeping before plastic became commonplace.

And Jim readily admits why plastic won. Five-gallon buckets were easier to handle and clean. Plastic honey containers didn't shatter on concrete floors. Plastic foundation reduced labor. Queen cell cups, protective clothing, hive components, and processing equipment all became more convenient.

But that history leads Jim to a more difficult question: what should beekeepers make of concerns about microplastics?

Jim discusses reports of microplastics being detected in honey and considers several possible pathways—from environmental exposure in air and dust to processing and storage equipment. At the same time, he repeatedly stresses uncertainty: he isn't arguing that honey is unsafe, nor does he claim science has established what these findings mean for human or honey bee health.

It's a thoughtful conversation about progress, tradeoffs, and a question that may deserve more attention as the science develops.
