Nesting by wasps in residential areas will affect the normal life, travel and personal safety of residents.

The venom of wasp can be divided into hemolytic toxin and neurotoxic toxin, which can cause the functional failure of human liver, kidney and other organs, especially if it stings human blood vessels, it will be life-threatening, and people with allergies will be very dangerous if they are stung. The stings of wasps are covered with a layer of non-toxic glands, which can attack or sting people many times.

After bee sting, the skin of wasp is red, swollen and painful immediately, and even petechiae and skin necrosis appear. After the eyes are stung, the pain is severe, and tears, redness and swelling may occur, and corneal ulcers may occur. Common symptoms include dizziness, headache, vomiting, abdominal pain, diarrhea, irritability and elevated blood pressure. The above symptoms usually disappear within a few hours to a few days; Severe cases may include drowsiness, generalized edema, oliguria, coma, hemolysis, myocarditis, hepatitis, acute renal failure and shock.

When residents are accidentally stung by wasps, after simple and correct wet compress, if the pain is effectively relieved and there are no other adverse reactions, there is no need to go to the hospital. If there are symptoms such as sweating, palpitation, chest tightness and breath holding, it means that the toxicity has spread. Don't delay. You should go to the hospital for detoxification and infusion immediately.
