I liked this article by Ernie, since it well reflected the typical learning curve of a newbee. The article originally appeared in the Summer 2023 edition of BeesCene, the journal of the BC Honey Producers’ Association, and is here included by permission.

Natural Beekeeping: A Reckoning
There is a great deal of argument about how “naturally” we beekeepers should manage our colonies. But the mere act of “keeping” bees implies that it is unnatural. Truly natural “beekeeping” would be to set out empty cavities (hives or other hollows) for swarms to move into (but not more cavities than would “naturally” exist...

A Study on Bee Drift and Mite Immigration Part 6 Randy Oliver ScientificBeekeeping.com First published in ABJ July 2023 In our 2018 study in the California foothills, we confirmed that bees indeed drift from collapsing colonies to other hives, even to those at considerable distance.

Beginning Beekeeping Class Notes
I’ve taught beginning beekeeping classes for many years. Over those years, I’ve made an outline of notes. I’ve put them into pdf format for your viewing or printout. These are rough notes, but are searchable for subject matter, as well as having a table of contents. (more…)
My first letter to the EPA
Letter to Linda pdf July 23, 2023 Subject: Clarification request for own use by beekeepers of generic natural miticides Dear Ms. Hollis, In a previous meeting, we beekeepers asked you about EPA granting beekeepers an own use exemption (similar to that in New Zealand’s [[A]]) for application of generic substances such as formic and oxalic...
Domain names held

Good News from the EPA !
Good News from the EPA!
