Beekeepers’ self-reported effectiveness of varroacides in managing varroa infestation, rated as having been completely successful, mostly successful, partly successful or not at all successful during the winter of 2021. The most common varroacide treatments in New Zealand are flumethrin, amitraz, and oxalic acid. Oxalic acid was divided into sub-categories, based on the three most common methods of application: sublimation, dribbling, or the in-hive placement of strips/staples that have been soaked in oxalic acid.
