The "BeeSauna", a German invention to control Varroa mites through precision heat control. While bees can tolerate temperatures up to 64°C, bee nymphs can only handle temperatures up to 42°C. Fortunately, the varroa's proteins are clotting at over 37°C. This device heats the hive to a constant temperature between 40°C and 42°C. Is this the perfect chemical-free solution?
