Why do bees sting?

Bees usually stick needles in their bodies and poke them out when they are violated. Bees don't sting people or other animals for no reason, it's just their instinct of self-defense.

Usually bees don't like black things and pungent smells, such as wine, onions and garlic. If people wear black clothes or have the above smell, it is easier to irritate people.

It is usually worker bees that sting people, whose needles are degenerated from ovipositor tubes and located at the end of abdomen. When a bee stings, it will die. The reason is that the stinger of bees consists of a back stinger and two abdominal stingers. The end of the stinger is connected with the large and small poisonous glands and internal organs in the body, and the tip of the stinger has barbs.

When bees sting people, the stinger's barb will hang on people's skin, so that it can't be pulled out. When a bee flies away by force, its internal organs will be pulled or even taken off, so everyone will die after stinging.

Extended data:

Zhao, an attending physician in the emergency department of the Third Affiliated Hospital of Southern Medical University, said that patients with mild symptoms of bee sting may have local pain, redness, burning sensation, blisters, ecchymosis, local lymphadenopathy and other symptoms, which can be treated urgently. Generally, these symptoms can disappear within a few hours to 1-2 days. However, if there is a serious allergic reaction, you should seek medical attention immediately.

Step 1: Remove bee bites.

Many stingers will stay in people's skin after being stung by bees. After being stung by a bee, you should first check whether there are stingers left in your skin. When you find them, you should pull them out carefully. It can be taped up and uncovered or pulled out with tweezers. No matter what kind of bee sting, you should drink plenty of water and replenish water to promote your body to eliminate toxins.

Step 2: Treatment of pain and swelling

Most people who are stung by bees are accompanied by local redness and fever-like pain. They can use ice packs to compress the wound and reduce its activity. They can choose soapy water, 3% ammonia water and 5% ~ 10% sodium bicarbonate solution to clean the wound. After pulling out the stinger, the skin can also be coated with 2.5% iodine tincture for 2 to 4 times. Because tincture of iodine can kill pathogenic microorganisms around the wound and destroy biotoxins.
