The Debate in Managing Mites: Embracing Data Over Dates

As an advocate for evidence-based apiculture, especially when it involves varroa mites, I champion the approach of collecting data to guide decisions. For those dealing with bee varroa, this implies performing mite sampling, tallying the numbers, and formulating a control strategy accordingly.

There was a time, perhaps a decade ago when varroa counts occasionally came back low enough to forego treatment. While that's rarely the case today, understanding your colony's health through data before introducing treatments is crucial.

Hesitations Among New Beekeepers

Conversely, there's an argument, notably from a fellow master beekeeper, suggesting that schedule-based treatments should be considered, particularly for newcomers daunted by the technicalities of varroa management. She argues that the complexity of sampling for varroa mites can be overwhelming for new beekeepers, who are already dealing with the steep learning curve of managing a vibrant hive. She observes:

"In our beekeeping community, we've noticed a trend: most newcomers shy away from regular mite sampling. As the colder months draw near, they often seek assistance, admitting they were unsure about the process and thus postponed it. The initial years are consumed with acclimatizing to the bustling hive, and conducting a thorough varroa count can seem daunting. Additionally, many are opposed to alcohol washes, fearing the loss of any bees."

This reluctance is not without consequence, as procrastination can lead to inaction until it's tragically too late and the hive succumbs to the infestation.

A Workable Alternative

To aid new beekeepers, Janet's club has devised a treatment protocol based on the beekeeping calendar—administering treatments post-harvest, before winter prep, and in the midwinter. This method is driven not just by dates but by significant apicultural milestones, which vary by region, providing a custom schedule for beekeepers in diverse environments.


While data-driven decisions remain my preference, I see the merit in Janet's protocol for varroa-resistant bees, particularly for beginners. It offers a manageable starting point for those hesitant about sampling or unsure of treatment methods.

Persistent Concerns

My lingering concern is that reliance on a schedule could impede the learning of essential skills, like diagnosing mite issues. Mastery of animal care, including beekeeping, requires understanding and performing all necessary tasks, even the unpleasant ones.

By neglecting to test for mites, a beekeeper might miss crucial information. For instance, without pre- and post-treatment counts, one cannot gauge the efficacy of the treatment. There could be a local rise in varroa-resistant bees, or you might inadvertently use an expired treatment without realizing it if you do not monitor mite levels effectively.

Testing's Role in Guiding the Novice

For new beekeepers, especially those unfamiliar with varroa DPI (Drone Pupal Injection) protocols or treatments like oxalic acid vaporization, testing is pivotal. It validates whether the treatment was applied correctly.

Furthermore, tracking data can influence future decisions. Should a product demonstrate diminishing effectiveness, a beekeeper informed by data would likely avoid its future use. High pre-treatment mite loads might also suggest an earlier intervention in subsequent years.


A Temporary Measure for Beginners

Janet's approach could serve as an interim measure while beekeepers gain confidence and expertise. Although sampling isn't anyone's favourite task, the value of the data it provides cannot be overstated. It has spared my colonies on more than one occasion, reminding me of its importance each time I hesitate.


On one occasion, despite using a product renowned for its resistance management, follow-up counts indicated no change in mite load. Without retesting and subsequent action, my hives would have been lost. To this day, I can attest that testing has invariably been more beneficial than not.


To the new beekeepers, if you are interested in varroa-resistant bees for sale, ensure you're equipped with both knowledge and practical experience. While initial guidance may lean on scheduled treatments, evolving towards data-driven management is essential for the well-being of your bees and the mastery of your craft.
