[Bonus] Short - Varroa Treatment Options: Amitraz aka Apivar

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.
