Thermal Varroa Treatment Temperature Guide

Research indicates that hyperthermia can be an effective non-chemical tool for controlling Varroa mites because these parasites are more sensitive to heat than their honey bee hosts. While adult bees can tolerate short periods of high temperatures, the margin of safety is remarkably narrow, as the heat required to kill mites in the brood is very close to the threshold that causes honey bee mortality or developmental issues. Effective thermal treatment typically requires maintaining a precise temperature of approximately 42°C (108°F) for several hours, often necessitating controlled humidity to prevent the bees from cooling the hive through evaporation. Various specialized devices, ranging from solar-powered hives to forced-convection heaters, attempt to exploit this biological vulnerability, though they differ in how they manage heat distribution and humidity. Ultimately, successful application depends on balancing the duration and intensity of heat to ensure maximum parasite reduction without damaging the colony’s long-term health or fertility. #honeybees #valleybeekeeping #hyperthermia #varroamites #treatment http://www.valleybeekeeping.com
