Treatment decision chart to aid beekeepers in selecting the most appropriate Varroa treatments for their colony situation and management goals. To aid in development of this chart, several assumptions about beekeeper efforts to prevent and manage Varroa are made. Hyperthermia recommendations are made based on the research referenced in Table 1, but caution is required when using this control method, as research regarding the safety of these devices is limited. Specific organic and synthetic chemical treatments are not mentioned in the figure; thus, beekeepers must determine which chemical treatments are available to them and follow the label of the given treatment. Recommendations in this figure are only intended to guide the beekeeper to available treatment options given the colony situation and management goals.
