The weather is getting hotter and hotter, and everyone prefers to go out and play than usual. Every morning and evening, on the roadside, meadows, parks, and hillsides, you can often see a small red mound that attracts more attention. Did your naughty kid want to touch it? A poke? Or even some boys are going to step on it?
Don't touch it! Don't poke! Don't step on it! Stay away!
Why? Because inside this mound is a very aggressive, highly poisonous, poisonous insect that can be deadly!
This poisonous insect is actually a kind of ant, called the red fire ant, and also has the name of "killer ant". They eat the roots, shoots, stems, seeds and fruits of crops, which have a great influence on crop growth. It can also bite poultry, livestock and humans. People who have been bitten will have itchy wounds, papules, wheals, blisters on the skin, and after healing, the skin will have black scars, chills, fever, dizziness and lymphadenopathy, and the whole body will show symptoms of allergies and shock, and at worst, there will be a risk of death. Summer is the peak of red fire ant activity.
Don't look at the small size of the red fire ant, that is you are deceived by its appearance, they are not unhurried, but you do not know its strength.
At about 9 p.m. on June 3, a man named Kai Pingzhen in Jiangmen, Guangdong Province, was wandering around the park, and suddenly felt that the position of his feet was extremely painful, and through the street lamp, he saw a lot of small black and red ants climbing up on his feet. His first instinct was to shake the ants away, but soon his feet were red, swollen and blistery, and he had difficulty breathing, even to the point of falling to the ground and unable to walk normally. After being sent to the hospital, Mr. Kai was successfully discharged from the hospital that night.
Why is the consequences of being bitten by this ant so serious? In fact, if you talk about it, this red fire ant, like the crayfish, is also an invasive creature. A few years ago, it was brought in from the United States through flowers, wood, organic fertilizers, etc., and became a destructive invasive organism.
The body length of the red fire ant is 3-7 mm, similar to the size of ordinary ants, why did it have such a name? Mainly after being bitten by it, there will be a burning pain. And a large amount of venom in the venom sac of the red fire ant will be injected into your skin, which will cause a violent burning sensation, and the local skin will form erythema or edema, and if the edema ruptures, it will cause a bacterial secondary infection. Among these venoms, there are also some water-soluble proteins, which will cause a small number of people to have allergic reactions due to physical problems, causing shock, spasms and other symptoms.
Where are the red fire ants most likely to appear? Farmland, wasteland, green belts, roadsides, orchards, parks,, etc., are all the favorite places for red fire ants to move.
So what should I do if I am bitten by a red fire ant? First of all, use soapy water to clean the wound as soon as possible to alleviate symptoms. Secondly, in addition to using soapy water, the wound can also be disinfected with iodophor. Again, if neither method has any effect, it is recommended to seek medical attention immediately. Finally, the common ants in the home are small yellow family ants, rhombus knot large-headed ants, indian large-headed ants, road ant, flat rainbow odorants, the probability of red fire ants appearing at home is not large, but ant activities, will carry a large number of pathogens, mainly for intestinal diseases of bacteria.
Therefore, once it is found that there are ants in the home, the most fundamental measure is to find the ant nest, wait for the ants to return to the nest, and use boiling water or concentrated alkali water to pour the ant nest.
