Red fire ants have spread to 12 provinces in China
On March 30, 2021, news from the Ministry of Agriculture and Rural Affairs showed that at present, red fire ants have spread to 12 provinces and 435 counties and municipalities in China. In particular, in the past five years, 191 new red fire ants have occurred in county-level administrative districts, which is a double increase compared with 2016. Where did the red fire ant come from? Why is it so serious after being bitten by a red fire ant, and how to save yourself? Pay attention to the passers-by, listen to the guests.
You must watch this video, especially friends in southern coastal cities, especially parents who have children at home! The red fire ant, listed on the list of the world's 100 most dangerous invasive alien species, has spread to North America, Asia and Australia since the 1930s. It has many serious hazards and poses a certain degree of threat to human health, agriculture and animal husbandry. Worse, it will actively replace native ants and arthropods, severely damaging the diversity of ecosystems and causing ecological disasters that are difficult to repair.
Red fire ants were first spotted
In 2004, the first discovery of red fire ants in China was in Wuchuan, Guangdong, and in 2006, it had spread to some areas such as Hainan, Guangxi. At present, Fujian, Jiangxi, Guangdong, Guangxi, Hainan, Sichuan, Yunnan and other provinces already have the existence of red fire ants, it can be said that a large area of the south has been "lost", and the impact has also increased. The red fire ant is currently constantly invading the north, and the northernmost part has invaded the Guangyuan area of Sichuan, which is the entrance door of the north, and after Guangyuan, it will reach the Qinling area and officially enter the north.
In general, the occurrence of red fire ants has a very high chance of contact with people, and it can be encountered in densely populated housing, school areas, and outdoor lawns. As long as it bites a person, it is very easy to trigger an "allergic" reaction, mainly because the tail spine of the red fire ant has venom, so after biting the person, there will be a stronger reaction. The red fire ant has powerful limbs and can support weight several times higher than its body weight, and when the palate clamps on the skin of a person, it is difficult to shake it off with one hand. The red fire ant took the opportunity to attack continuously with the claw needle in the tail of the abdomen, and with each sting, the venom sac released venom. First the pain like being stirred by fire, then blisters appeared. After expert analysis, 98% of people will only feel pain and discomfort! However, a small percentage of people who are allergic to the venom in the venom develop anaphylactic shock and are at risk of death! If the blisters or pustules are broken, it is easy to cause secondary infection of bacteria when not paying attention to cleanliness and hygiene.
How to deal with red fire ants encountered outdoors
When you are outdoors and find red fire ants, remember! Be sure not to be curious to study the nest of the red fire ant, especially if the child loves to play, be sure to control the child, do not destroy the red fire ant nest. The main biological characteristic that distinguishes red fire ants from ordinary ants is aggressive. Therefore, once the vibration occurs near the nest, thousands of red fire ants will pour out of the nest and quickly climb to the hands and feet, which will inevitably be painful and even allergic death. So when you find the nest of the red fire ant, try not to participate in the suppression of the red fire ant, you should report to the local agricultural department as soon as possible!
If you are unfortunate enough to be bitten by a red fire ant, try not to deal with it yourself, and it is the safest thing to do if you seek medical treatment at the first time. Never underestimate any ant, any toxin-carrying creature. I hope that everyone forwards this video, so that more people have a basic sense of security, passers-by here thank you!
