In this Varroa Treatments short, Jeff Ott and co-host Dr. Becky Masterman welcome Dr. David Peck from Betterbee to discuss formic acid—a powerful tool in the fight against varroa mites. David explains how Formic Pro, the most common formic acid product now available in the U.S., is formulated to safely release vapors that penetrate capped brood cells, killing mites both on adult bees and developing brood.

David and Becky highlight both the strengths and cautions: formic acid’s ability to deliver a fast, thorough mite knockdown, its temperature sensitivity, and its potential to cause temporary brood loss or even queen replacement in stressed colonies. They emphasize protective gear, ventilation requirements, and why strong colonies benefit most from treatment.

From freezer tricks to reduce fumes, to understanding normal bee behaviors like bearding after application, this episode gives beekeepers the knowledge to use formic acid effectively and safely—making it a valuable addition to a year-round mite management plan.

In this installment of the Varroa Treatment Series, Jeff and Becky welcome Dr. David Peck of BetterBee to discuss oxalic acid treatments, one of the most widely used organic options for controlling Varroa mites. The conversation explores both oxalic acid vaporization (OAV) and the dribble method, breaking down how each is applied, safety considerations, and when they are most effective.

David explains the differences between registered products like Api-Bioxal and EZ-OX, recent label updates allowing higher dosages, and practical tips for using each method safely—particularly the critical need for proper respiratory and eye protection with vaporization. He also shares insights into when broodless periods provide the greatest impact, why oxalic acid poses minimal risk to bees but requires careful handling by beekeepers, and what research still doesn’t know about how this acid kills mites.

This episode is an essential listen for beekeepers looking to add oxalic acid—whether dribble or vaporization—to their integrated mite management toolkit.

In this BTPS Varroa Treatments short, Jeff and Becky are joined again by Dr. David Peck of Betterbee to explore amitraz—known commercially to most U.S. beekeepers as Apivar. As a synthetic miticide, Apivar has long been a cornerstone of mite control due to its effectiveness, wide temperature range, and bee-friendly properties. But as with many tools in the beekeeper’s arsenal, its strength may also be its vulnerability.

David explains how amitraz works by overstimulating the varroa mite’s nervous system, effectively paralyzing and killing the parasite while leaving bees largely unaffected. The treatment avoids comb contamination and breaks down quickly in the hive, making it an appealing option for many beekeepers—especially in late summer or early fall once honey supers are removed.

However, the discussion also delves into growing concerns about resistance. Increasing reports, particularly from commercial operations, suggest amitraz is not as effective as it once was. Resistance genes in varroa populations have been linked to recent large-scale colony losses, and misuse or overuse of the chemical—including unapproved, home-mixed applications—may be accelerating the issue.

The takeaway? Apivar can still be a reliable tool when used properly, but its effectiveness isn’t guaranteed. Rotating treatments, testing for mites, and monitoring efficacy are essential. This episode highlights not only the promise of amitraz but also the need for responsible stewardship of every miticide in the beekeeper’s toolbox.
