Mosquitoes become more difficult to deal with 3 “weapons” to drive away mosquitoes
At night, the pillows buzzed constantly, but they could only use electric mosquito coils and mosquito repellent water to go into battle; just go out the door, even in the office, and be bitten by two or three bales if they are not careful; they will hurt after being bittenItching for several days could not be cured, and some people even swelled their entire feet . People have talked that this year’s mosquitoes seem particularly fierce, and some people say that this year is “the year of mosquitoes.”
The British “Daily Mail” also recently published an article pointing out that this year’s phenomenon of mosquitoes is extraordinarily large. Experts said that this is because the wet spring coupled with the wet summer provided perfect conditions for mosquitoes to survive.
The World Health Organization states that mosquitoes are the number one killer of humans.
In the late summer and early autumn, mosquitoes bite more severely. How to prevent mosquitoes scientifically becomes a required course.
The density of mosquitoes in Jiangsu, Guangdong and other places has soared. Ms. Zhou suffered from mosquito bites and was often besieged with large bales on her hands, legs, and feet.
“The most annoying thing is that when the light is turned off, it ‘buzzes’, and when it is unbearable to turn on the light to prepare for a final battle with it, it is nowhere to be found!
“Grandma Yang, who lives in the Beijing community, also feels that this year’s mosquitoes are very powerful:” Electric mosquito coils do not work at all. Mosquitoes are still there. Last summer, they were not so serious.
“The mosquitoes that are raging are giving parents even more headaches.
A mother complained, “The mosquitoes especially bite the ground, always biting the child’s eyelids and soles.
A few days ago, the child’s head was bitten by a big bag, and he couldn’t get down for three or four days. He was really worried about getting the virus.
“The mosquito density monitoring data released by CDCs across the country shows that mosquito density has indeed increased in some areas this year.
The density of mosquitoes in Hubei Province from April to May this year was twice that of the same period last year; the density of mosquitoes in Chongqing Wanzhou from May to June was more than five times that of the same period of last year;The mosquito density has even increased 13 times compared to July last year.
Dermatologists say that there are some patients who are allergic to mosquito bites every year, and the number of patients this year is about the same as in previous years.
However, the situation in Chongqing is not optimistic. The Chongqing Children’s Hospital treated almost 4,000 mosquito bites in April this year, and some of them were more serious.
Mosquitoes are becoming increasingly difficult to deal with. Experts say that there is no exact data to confirm that there are more mosquitoes this year than in previous years, but the density of mosquitoes has indeed increased in some areas with heavy rainfall and even rain distribution.
Some data confirm that with the rise in global temperature, the distribution of Aedes albopictus (also known as the “flower mosquito”), which originally lived in tropical areas, has become wider and wider in recent years, with both numbers and densities increasing.
This kind of mosquito can appear during the day, so many people think that “mosquitoes dare to bite people during the day,” and they feel that mosquitoes are getting more and more fierce.
Mosquito populations are constantly evolving, which makes them increasingly difficult to deal with.
Experts say that the essence of biological evolution is survival of the fittest.
In the fight against human beings, mosquitoes that fly slowly and sound loudly were killed, those with poor drug resistance were “smoked” to death, and the remaining “fighter” of the vampire family.
With the continuous use of anti-mosquito drugs, the mosquito’s drug resistance has generally increased, and the “aggressive force” has become stronger and stronger.
A study by the British Medical College found that mosquitoes are gradually “ignoring” DEET, a substance that is widely used in mosquito repellents and toilet water.
Three “weapons” to drive away mosquitoes Mosquitoes are the “number one killer” that threatens human health.
Dengue fever, which threatens 2.5 billion people worldwide, is transmitted by Aedes albopictus and Aedes aegypti, and 1 billion people in China are at risk of being infected.
Mosquitoes can also infect three diseases: malaria, chikungunya fever, and encephalitis, which pose a great threat to human health.
Experts remind scientific mosquitoes to learn to use three “weapons”.
Physical weapon: mosquito net.
Since ancient times, mosquito nets have been the most primitive and effective way to prevent mosquitoes.
Elderly people, young children, pregnant women and people with chronic diseases who are less resistant are suitable for mosquito nets.
The American Academy of Pediatrics also recommends that mosquito nets and trousers are the best way to protect children from mosquitoes.
Chemical weapon: DEET.
The US Centers for Disease Control and Prevention recommends DEET, Imanin (mosquito repellent), ecaride, and lemon eucalyptus leaf oil to drive mosquitoes.
However, Tianjin drug research experts reminded that although these “chemical weapons” are not much in the electric mosquito coils / liquids, they are pesticide-based components. When the concentration is too high, they may cause headaches and nausea.
Therefore, it is best to use it for 1 to 2 hours during the day when no one is at home.
Electronic weapons: mosquito killer.
In many communities, there are blue-purple insect-killing lamps. They use the phototaxis of insects to attract mosquitoes and then kill them with ultraviolet rays or electricity.
There are also some mosquito killing lamps that use carbon dioxide, temperature, odor, etc. as bait.
Experts caution that the fundamental way to avoid mosquito bites is to dislike them.Studies have shown that mosquitoes like the “taste” of carbonic acid. They also like people who have high body temperature, sweat easily, and love black clothes.
Therefore, when it is hot, wipe off the sweat in time, take a bath as soon as possible after exercise, use less perfume, body lotion and other cosmetics, try to wear less black clothes, and change the vase and hydroponic plants thoroughly once a week, so that you can start from the sourceGet rid of mosquitoes.
After being bitten by a mosquito, you can apply some alkaline substances such as soap, baking soda, etc. to the bite, or you can use a hot towel for a while.
It should be noted that the more itchy it gets after being bitten by a mosquito, and it is not easy to subside, it should be avoided as much as possible.
Just 15 minutes after being bitten, the headache and itchy sensation will disappear. You can apply some products such as wind oil essence, cooling oil, etc. to cool itching.
