Many of us struggled with wasps in the warm season. For some, this meeting ended very badly. A sharp pain, a burning sensation, a swollen condition at the site of the bite – all of this is firsthand known to us. Wasps are not in vain considered one of the most dangerous stinging insects. In some cases, wasp bites, like other bees, can cause death. There are a large number of different types of wasps in the world. Each of them is unique in its own way. But today we will talk about such a wasp of which only one form freezes the blood in its veins.
Where does the largest wasp in the world live?
The largest representatives of the wasps are hornets. There are a little more than 20 species in the world, but against the background of all I would like to highlight the largest and perhaps one of the most poisonous insects in the world. Vespa Mandarinia or the giant Asian hornet. Their size can reach almost 6 centimeters and the wing span is 7.5 centimeters.
They live, as the name implies, mainly in the countries of Southeast Asia: Korea, China, Japan and India. Populations of these hornets can also be found in the Russian Primorye.
Nests consist of chewed bark pieces that are held together by a sticky saliva secretion. The Hornet Queen initially takes care of the nesting arrangement. At the beginning of the warm season she lays eggs and looks for food for hatched larvae. One month later, the adult young hornets take over all the tasks of feeding new larvae and protecting the hive. And the queen is busy only with the production of new offspring.
Professionals are constantly looking for food. In the diet unpretentious: eat plant-based foods that contain sugar (honey, nectar). Adults also hunt insects.
How dangerous is the huge Asian hornet?
The giant Asian hornet is a true honeybee nightmare. According to entomologists, only 30 such "heroes" are capable of destroying a 30,000-headed bee colony in just three hours. Hornets rarely use a sting to kill their victims. For this purpose, they have strong jaws, with which they literally eat the victim's head. Little bees against these giants have no chance. After killing a bee or other insect, the giant Asian hornet chews prey into a soft substance and carries it to her hive to feed the cubs.
The Asian Giant Hornets live in colonies for about six months, but at this time they manage to do much mischief. Huge Asian hornets have a very bad reputation among the inhabitants of the countries where they live. Your bite can be deadly, especially for a person who is sensitive to insecticides. According to official figures, an average of 40 people per year die in Japan and China as a result of a huge wasp. Basically, beekeepers try to protect their bee land.
With its 6-millimeter stitch, the hornet injects poison that contains several very powerful toxins. The penetration into the soft tissue leads to the destruction of the cells, which is accompanied by immediate edema and inflammation. The hissing bite is very painful. In addition, unlike the same bees, they can sting again and again. After a bite the bee loses its sting, but the hornets keep it like the wasps. With numerous bites more and more poison is injected.
"Imagine that you put a glowing nail or a drill under your skin," says the experienced Asian hornet bite itself.

How do you protect yourself from attacks?
As this insect settles in a colony, at the first sign of danger, it attaches a special pheromone, which is a signal of danger to others. Entomologists advise not to provoke insects to aggression: to not approach the beehive in which they live, not to try to examine it, to make any sudden movements, to wave their hands. Attack immediately. And in open terrain, they will catch you – they fly very fast. So close to the hive it is better to be very quiet and walk slowly.
What to do if bitten?
If the victim receives first aid early after the insect's bite, the serious consequences can often be avoided. The first step is to check for the presence of the sting at the bite site (when the hornet has been struck at the bite site). Rinse with clear water. When bitten, this insect releases only 2 mg of venom. The poison is contained in a special bag. If the sting is not removed, all the poison gradually falls into the wound.
The second step should be the processing of the bite site. If possible, it should be disinfected with a weak solution of potassium permanganate or hydrogen peroxide. First Aid should include the provision of abundant hydration regime. To relieve pain, apply ice or a clean piece of cloth moistened with cold water to the area of the bite.
If you do not know if a person is allergic to bites, you should take antihistamines immediately. If a person suffers from an allergy, the ambulance may not arrive on time. After that, a doctor must be consulted.
