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.
