Hornet stings are more painful to humans than typical wasp stings because hornet venom contains a large amount (5%) of acetylcholine. [ 8 ] [ 9 ] Individual hornets can sting repeatedly. Unlike honey bees , hornets do not die after stinging because their stingers are very finely barbed (only visible under high magnification) and can easily be ...
Most cases of stings from V. crabro do not require medical attention, but rarely can be serious. A documented case requiring treatment displayed symptoms including tingling at the site of the sting, headaches, and shortness of breath. In the hospital, the victim was found to have a fast, irregular heartbeat with a blood pressure of 111/63.
Vespa tropica, the greater banded hornet, is a tropical species of hornet found in Southern Asia, New Guinea and west Africa, and which has recently been discovered to be an invasive species on the Pacific island of Guam. It is a predator of paper wasps and possesses a potent sting, which can cause extreme pain and swelling.

Worried about getting stung by a jellyfish at the beach? Here's how to navigate the worst-case scenario.
Many arthropods bite or sting in order to immobilize their prey or deter potential predators as a defense mechanism. Stings containing venom are more likely to be painful. Less frequently, venomous spider bites are also associated with morbidity and mortality in humans. Most arthropod stings involve Hymenoptera (ants, wasps, and bees). While ...
The hornets can devastate a colony of honey bees, especially if it is the introduced western honey bee. A single hornet can kill as many as 40 bees per minute due to its large mandibles, which can quickly strike and decapitate prey. [91] The honey bees' stings are ineffective because the hornets are five times their size and heavily armored.
