Identification of red fire ants
Red fire ants, reddish-brown in color, larger than ordinary ants, often appear in woodlands, farmlands, parks, residential areas, green belts, rivers, and ponds. Mature nests arch about 10 centimeters out of the ground, forming small fluffy mounds, and the number of red fire ants in a nest can reach up to 500,000.

Unlike ordinary ants, red fire ants are very aggressive. When a red fire ant stung, it is mainly pierced with a tail sting needle and released venom.
The bite will be painful, followed by redness, swelling and suppuration.

Recently, when a man in Shixing County, Shaoguan, Guangdong Province, was accidentally bitten by red fire ants when he went home to sweep the grave, and his limbs were weak and difficult to walk on the spot. Fortunately, it was found by the passing town and village cadres that the man was in shock when he was taken to the hospital, but fortunately, the rescue was timely, and now the man has recovered.
So, if you are accidentally stung by red fire ants, what should you do? ↓
1. Do not dust off red fire ants with your hands, red fire ants will attack with poisonous needles many times. Be sure to pat the red fire ants with a handkerchief or towel to prevent further injury.
2. Immediately after the injury, rinse the punctured area with cold water, which can not only wash away part of the venom, but also prevent other bacteria from entering the body through the wound.
3. Apply ointment: In general, it can be applied topically with steroid-containing ointments such as dermatitis flat and Pikang cream. Mosquito bite control ointments commonly sold on the market contain antihistamines, which can be used to relieve itching and swelling.
4. Try to rest for a few hours after being stabbed. If you feel dizzy, nauseous, throbbing, etc., during this process, it may be a sign of anaphylactic shock, and you need to call an ambulance to go to the hospital immediately.
5. If red fire ants are found, they need to contact the relevant departments immediately for investigation and removal, so as to prevent them from continuing to multiply and expand the damage.
Note: Be sure not to attempt to spray the nest yourself with pesticides or remove the nest with hot boiled water, as this behavior may prevent professionals from finding the nest and affect the eradication effort.
Tips for dodging red fire ants
1. Do not stay in damp places with a lot of mosquitoes, such as grass and trees.
2. If you encounter a large number of red fire ant colonies, do not step on them or touch them with your hands.
3. Red fire ant nests are relatively easy to identify, and they are easy to highlight after rain, so when you see a honeycomb-like nest, you should avoid it in time and do not damage the nest.
