In the spring, the weather is getting warmer and the sun is shining brightly. Cherry blossoms, peach blossoms, apricot blossoms, pear blossoms…competitively attract many friends to go out and play, but also attract many insects such as bees, wasps, red fire ants, etc. If you go out for food, you must remember these first aid knowledge if you accidentally “cross paths”.
How to avoid getting stung by bees?
In the wild, common invading bees are bees and wasps. They all belong to the same phylum and class of Hymenoptera, but belong to the family Apisidae and Vespa. The toxicity is far greater than that of the honey bee family, and it is more likely to cause severe bee stings.
Apiidae venom is mainly polypeptide, which is acidic. Only worker bees (female) have stings with barbs. Each worker bee can only sting Once, the venom sac remains after the sting and continues to release toxin.

Because it stings a person once, the little bee will die, so bees generally do not take the initiative to attack people. When we go out to play, be careful not to wear brightly colored clothes, and do not spray strong perfume. If there are some flying bees around, it is best to stand still and keep calm and let them fly away by themselves. Bees mistakenly think they are attacked and sting us.
If you are accidentally stung by a bee, don’t be too nervous. Bee venom usually causes mild local reactions, such as pain, swelling, congestion, and burning sensation. The stinger in the skin is pulled out.

For minor stings, try cold compresses, wash the sting site with water or soapy water, or take pain relievers to relieve pain symptoms. Mild symptoms usually appear within a few hours or 1 disappeared within days.
However, if you have symptoms such as fever, headache, nausea and vomiting, coma, or even anaphylactic shock such as laryngeal edema, difficulty breathing, and confusion, you must seek medical attention in time.
What should I do if I get stung by a wasp?
Wasps, also known as wasps and wasps, are highly toxic, widely distributed, fast-flying, and diverse insects. They have social behaviors and live in groups as their main way of life. When they feel When infested, it is easy to launch group attacks.

Vapidae venom is mainly protein-based, weakly alkaline, has no barbs, can repeatedly sting humans and animals, toxic Stronger than bees, aggressiveness and desire to protect the nest are also stronger than bees.
After being stung by a wasp, the local swelling and pain are obvious, and symptoms such as dizziness, nausea and vomiting, facial edema, dyspnea, irritability, etc. may occur, and even anaphylactic shock, liver and kidney failure, coma and death. In people allergic to bee venom, even a single bee sting can trigger a severe systemic reaction.
When encountering a hornet’s nest on the road, make a detour, don’t approach it curiously, and don’t stab the hornet’s nest, so as not to disturb the wasp. And use clothing to protect your head and neck, don’t run wild, lest the wasps swarm chase.

If you are accidentally stung and have venomous stingers, first pull out the venomous stingers, rinse the wound with running water or a weakly acidic liquid such as vinegar, apply ice to the sting area to relieve pain, and then use Apply a cream containing antihistamines, anesthetics, corticosteroids or a mixture of the three and observe for half an hour. If you find allergic reactions such as difficulty breathing, thickened breathing, and wheezing, you should go to the hospital for treatment immediately.
Stay away from this little mound
Although sometimes, in order to show that the injection doesn’t hurt at all, we will say “it’s like taking a bite from an ant”, but if such an ant bites, a seven-footed man may not be able to bear it. shed painful tears.
As a dangerous invasive alien species, RIFA is native to South America and first entered my country in 2004, when it was first discovered in Taiwan, my country, and by 2004 In September of this year, RIFA was also found in Wuchuan City, Guangdong, and now RIFA has spread to 435 counties in 12 provinces across the country.

The RIFA is nicknamed “the invincible ant”, so you can see how powerful it is. Different from ordinary ants, there is a large amount of venom in the venomous sac of the red fire ant. Once it bites a person, the venom will be injected into the skin, and the wound of the bitten will have a strong burning sensation, and even cause the whole body to swell and cause shock. will also die.
In recent years, there have also been common reports of RIFA injuring people, such as children being bitten while playing in the park, farmers being bitten while working, and even citizens being bitten while walking in the community .

When bitten by RIFA, do not scratch, so as not to cause secondary infection, you can wash the bitten place repeatedly with soapy water, keep the wound clean, use cold water or ice cubes Apply a cold compress to the bitten area.
If a person is allergic to the venom protein in RIFA toxin, there will be confusion, shock, and fainting. About 0.2% of patients will experience convulsions and symptoms of acute renal failure after being bitten. Therefore, if you have a history of allergies, or have a severe reaction after being bitten, you must seek medical attention in time.
In short, after the weather is getting warmer, all kinds of insects are also active. When you go out to play, pay attention to protect yourself, don’t panic when you encounter bees and wasps, keep calm and let them fly away , Protect your sweets and snacks, don’t spray yourself with fragrance, it is easy to “attract bees and butterflies”, if you have an allergic reaction after being stung, you need to seek medical treatment immediately.
