I’ve heard from a number of Newfoundland beekeepers who support the Varroa Action Plan released by NL Beekeeping Association and are interested in the upcoming workshops on how to detect, treat, and prevent the spread of Varroa, but can’t do it for one reason or another. Fortunately there are plenty of instructional videos about Varroa online that might be as informative for beekeepers who won’t be attending the workshops. Here are a few:

Another aspect of preventing Varroa from spreading are sentinel hives, hives set up near entry points (such as ports) to detect Varroa incursion early so action can be taken early. Sentinel hives have been around for a long time. Here are some informative results that a simple Google search for “sentinel hives” produces:

I offer up some other beekeeping resources that are easy to explore and to learn from on this page. Let curiosity be your guide. Happy hunting, and good luck.
If more resources pop up on my radar, I’ll list them here:
Honey Bee Health Coalition — lots of tools and videos about Varroa.
