The wasps are the only representatives of hymenoptera which use their sting to defend themselves as well as to attack their victims. 

The wasp itself is a “vegetarian” but the larvae feed only on insects and arachnids. Therefore, “as a loving mother”, it is forced to hunt. 

It was found that the different genera of wasps are specified in hunting only one kind of insect or arachnid. Their knowledge about the anatomy of the victims is incredible. Wasps know the right places to sting; the targets are the nerve knots. For example the prey of Cerceris wasps is always only one kind of a beetle,Bothynodes punctiventris. Sphex wasps hunt crickets and have to sting them exactly on three point of the body. The Ammofia feed their larvae with caterpillars; there are 9 ganglions to paralyze in the body of those caterpillars. However, the most selfless ones are Pompiuswasps, hunting the deadly poisonous for them tarantulas. Victims do not die and that is essential for the larva; it is alive but motionless. 

Wasps can often be seen in the settlements of people, so a wasp sting is a common poisoning. The neurotoxin cannot cause death but it can lead to a clinical picture equal to the one of a honeybee sting. Wasp sting is more dangerous as a rule. It is important to notice that the sting rarely remains in the skin and the wasp usually flies away freely. 

Preventive measures:

  • Destroy all Hymenoptera’s nests around your living place
  • Keep your feet covered outdoors
  • Avoid bright colored clothing and perfumery products
  • Prefer to wear tight that floppy clothing
  • When you encounter the insect, stand still or retreat slowly. If it lands on skin, quickly brush it off. 

  • Use the personal first aid kit in individuals with a history of allergy 
    First aid: 
    1. Removing the sting
    2. Tightening up the limb above the affected place 
    3. Treatment of the wound with tap water or antiseptic solution and applying a cold compress
    4. Antihistamine (antiallergenic) medicines in severe cases
    5. Intravenous corticosteroids and subcutaneous adrenaline in cases with anaphylactic shock
