The centipede is afraid of the sun, likes tidal wetlands, lives in rotten wood, stone gaps or wet grass, and occasionally hides in clothes.

Symptoms and treatment of centipede bite

When bitten by a centipede, its venom glands secrete a large amount of venom, and the venom glands of the cis-palatal teeth are injected subcutaneously into the victim's skin, resulting in poisoning. The bigger the centipede, the more toxins are injected into the stings, and the more serious the poisoning symptoms are. Centipede venom is acidic and contains two toxic ingredients similar to bee venom, namely, histamine-like substance and hemolytic protein, as well as tyrosine, formic acid, fatty oil, cholesterol and so on. After being bitten by a centipede, the bitten site is red and swollen, pain, blisters, necrosis and lymph nodes, lymphangitis, accompanied by fever, nausea, vomiting, headache, dizziness, coma and shock.

The critical degree of centipede bite should take into account the following factors: the size of ① centipede is related to the amount of venom injected. Local symptoms and systemic poisoning symptoms of ②. The manifestation of allergic reaction of ③.

1. Small and medium-sized centipede bites have local pain, with white round bumps, followed by redness, edema, epidermal necrosis and lymphadenitis, which generally improve and disappear within 1-3 weeks. Some patients still had local swelling and itching 1 month after injury without effective treatment.

two。 Large centipede bite local burning swelling, severe pain, burning pain is unbearable. Severe cases may appear local blisters or necrosis, with obvious lymphatic vessels and lymphadenitis. Systemic poisoning symptoms can also occur after toxin absorption. Such as dizziness, dizziness, nausea, vomiting, fever, and even delirium, convulsions, coma. Young children often have severe systemic symptoms because of their light weight.

3. Allergic reactions some patients have allergic reactions similar to bee venom, allergic symptoms, and even anaphylactic shock, and death cases are reported.

(1) the centipede venom is acidic. After a bite, the upper part of the injured limb should be fastened with a cloth band for 1 to 2 minutes every 15 minutes. Ice can be applied around the wound, the skin of the wound can be cut, and the venom can be sucked out with suction or cupping. Immediately rinse the wound repeatedly with alkaline solution (3% medical ammonia, 5% sodium carbonate or soapy water) to neutralize acidic venom. Centipede bite marks are a pair of small holes, venom is flowing into the small holes, so be sure to rinse repeatedly with alkaline water, avoid using iodine tincture or acid drugs to rinse or wipe the wound.

(2) after washing the wound, the following treatment methods can be selected:

After grinding the powder of ① realgar and licorice, apply the affected area evenly with tea oil.

② crushed 1 to 2 pieces of snake medicine tablets and applied them to the affected area with cold boiling water.

③ takes the smoke oil from the dry chimney and smears the wound area.

④ smeared the wound with saliva from the mouth of the rooster (lift the rooster upside down and saliva can flow out).

⑤ or take fresh, dandelion, half lotus, houttuynia, mint leaf, fresh mulberry leaf, lentil leaf, seven leaves a flower, purslane, fresh taro tip, sweet potato and other Chinese herbal medicine, choose one or several kinds, wash and smash the affected area, which has the effect of relieving pain, itching and detumescence.

(3) those with severe pain can take some painkillers appropriately; those with signs of allergy can take chlorpheniramine 4 mg, 3 times a day, or 1 tablet a day. After the above treatment, if the swelling and pain does not subside, the symptoms aggravate, or the systemic symptoms are serious, they should be sent to the hospital for treatment in time.

The way to expel the centipede

The centipede is highly toxic and is likely to be life-threatening if it is not treated in time by the centipede. Therefore, if there are centipedes entering the room, we must find ways to expel or kill them. In general, there are several simple ways to kill centipedes:

1) place camphor balls in places frequented by centipedes

2) sprinkle lime powder on doorways and windows and other places where it is possible to climb into the centipede

3) use pyrethroid spray to kill centipede

4) close the room and ventilate the room after fumigating with moxa grass

5) the diluted solution of realgar water or dichlorvos should be sprayed on the floor and corner of the house for half a day.

How to prevent centipedes

Centipedes like humid living conditions. Therefore, in order to reduce the chances of centipedes staying indoors, we should pay attention to the following points:

1) keep the room dry and usually open more windows for ventilation. If it is impossible to reduce water vapor through doors and windows, use desiccants such as quicklime for dehumidification, or use an air dryer for dehumidification.

2) centipedes like to live close to the ground and often hide in caves or cracks. Therefore, once a centipede is found in the house, it is necessary to clean up the indoor sundries, do not have objects everywhere on the ground, and try not to form a small gap between the sundries and the ground. If you do not give the centipede a place to hide, it will naturally leave and find another hiding place.

3) the centipede enters the room, often because the house is surrounded by a humid environment, which is suitable for centipede life. In some cases, centipedes break into human homes intentionally or unintentionally. Therefore, flower bed planning and layout had better stay away from doors, windows and wall roots, and do not pile sundries close to the wall roots, so as to reduce the possibility of centipedes entering the house.

4) centipedes often enter the room through cracks in doors, windows and walls. Centipedes are creatures active at night, so it is necessary to close doors and windows at night, especially in hot summer, where many people open doors and windows at night to enjoy the cool, which can easily lead to centipedes entering the house. If there is a crack in the wall, it must be blocked.
