Hornet Nest

The stings of the Asian giant hornet (Vespa mandarinia) are the most venomous known, and are thought to cause 30-50 human deaths annually in Japan and 42 in China in July-September 2013 alone. Non-queens being 1.4-1.5 inches in length, the Asian giant hornet's venom can cause allergic reactions and multiple organ failure leading to death, though dialysis can be used to remove the toxins from the bloodstream.
People who are allergic to wasp venom are also allergic to hornet stings. Allergic reactions are commonly treated with epinephrine (adrenaline) injection using a device such as an epinephrine autoinjector, with prompt follow-up treatment in a hospital. In severe cases, allergic individuals may go into anaphylactic shock and die unless treated promptly.
In Jewish tradition, it was once believed that the sting of a hornet could be soothed by crushing a housefly and applying it to the site of the wound.
