This research investigates the potential use of organic waste as an alternative and sustainable approach to managing Varroa destructor. Current Varroa treatments rely heavily on synthetic acaricides, which not only risk contaminating honeybee products, but also face increasing resistance among mite populations. In contrast, organic waste — exclusively from food and beverage manufacturing — may have the potential to display acaricidal properties and promotes a safer and more sustainable solution.
Results indicated concentration-dependent toxicity from three organic waste extracts at different concentrations (15%, 30% and 60%), though interestingly, the highest concentration (60%) did not reduce bee survival, possibly due to repellent effects. In addition, the organic extract obtained using the technique of mechanical leaching demonstrated the most favourable animal safety profile.
This research supports a circular economy by upcycling organic waste into value-added biopesticides, offering industry stakeholders a sustainable alternative for Varroa control. Recommendations include further development of organic waste treatments with a focus on safety, efficacy and field applicability.
