Can mosquitoes spread the Wuhan coronavirus? Here is the most effective way to kill mosquitoes!

In a few days, the annoying mosquitoes will start to become active. When it comes to mosquitoes, everyone is familiar with them. They like to suck people's blood and sometimes spread some viruses in the human body. Now during the new coronavirus epidemic, many people have begun to worry about whether mosquitoes can spread the new coronavirus. So, can mosquitoes spread the new coronavirus? What are the most effective ways to kill mosquitoes?

Can mosquitoes spread the new coronavirus?

1. Can mosquitoes spread the new coronavirus?

There is currently no evidence whether mosquitoes can spread the new coronavirus. Although mosquitoes can spread many viruses, including Japanese encephalitis virus, dengue virus, yellow fever virus, West Nile virus, Zika virus, etc., these viruses enter the human blood through the mosquito's saliva when the mosquito bites and make people sick. What is known now is that the new coronavirus is mainly transmitted through the air and contact. There is currently no evidence that mosquitoes can transmit the new coronavirus. In addition, SARS and MERS viruses, which are "close relatives" of the new coronavirus, have not been found to be able to be transmitted through mosquito bites during previous epidemics. Therefore, there should be no possibility of mosquitoes transmitting the new coronavirus, and the coronavirus is not a mosquito-borne virus.

2. How long can the new coronavirus survive?

According to my country's new coronavirus pneumonia prevention and control plan (fourth edition). The new coronavirus is sensitive to ultraviolet light and heat. 56°C for 30 minutes, ether, 75% ethanol, chlorine-containing disinfectants, peracetic acid, chloroform and other lipid solvents can effectively inactivate the virus.

The virus survives for different periods of time in air at different temperatures and humidities. The virus can be completely inactivated at 56°C in 30 minutes. At room temperature around 25°C, the virus will quickly lose its infectiousness. Normally, after the new coronavirus leaves the human body, it can only survive for 48 hours in a dry environment, and its activity drops significantly after 2 hours in the air. However, the virus can also be transmitted through contact. When droplets containing the virus settle on the surface of surrounding objects or the hands are contaminated with the virus, they will contaminate the surfaces of the objects they touch. On these smooth surfaces, if the temperature and humidity are appropriate, such as 20°C and 40-50% humidity, the new coronavirus may survive in vitro for five days.

3. How to most effectively kill too many mosquitoes at home?

1. Soapy water. Close the doors and windows, place a basin in front of the window, add some water mixed with laundry detergent, and the next day, there will be some dead mosquitoes in the basin. "If you continue to use this method every day, you will almost no longer need to spray insecticide to kill mosquitoes. And there will be fewer and fewer mosquitoes. Laundry detergent is alkaline, and mosquitoes are not suitable to grow in alkaline water. However, there are spices in the laundry detergent water, which will make the female mosquito mistakenly think that there is food and lay eggs in it. Thus, the effect of killing mosquitoes is achieved.

2. Salt water and toothpaste. If you are bitten by a mosquito by accident, don't rush to scratch it with your hands. Apply some salt water or toothpaste to the affected area to quickly relieve the itching. This method is safe and simple for children. You know, any medicine is more or less harmful to the human body, not to mention the delicate skin of children. If your child is bitten by a mosquito, apply salt water immediately. It can relieve itching and swelling without any side effects.

3. Spray insecticide. It is mainly a chemical insecticide called pyrethrin. It can be sprayed in stairwells, bathrooms, toilets, kitchens and other places to effectively kill mosquitoes. However, it should be noted that you should not spray too much pesticide, as this will not only waste it but also pollute the environment. The best time is after dinner.

4. Gently drop a few drops of medicated oil on the used mosquito coils that have lost their efficacy, plug in the power supply, and you can achieve a stronger mosquito repellent effect while saving tablets. If there is a power outage, you can light one or two used tablets together. After a few minutes, they will have the effect of repelling and killing mosquitoes.

5. Be diligent in cleaning and avoid being lazy. After eating, do not throw the dishes directly into the sink, because unwashed milk cups or plates with noodle sauce will attract more mosquitoes, so be sure to clean them in time. Of course, don't forget to clean up the food scraps spilled on the table and stove, because mosquitoes will attach themselves to food no matter where it is.

6. Take a bath frequently or eat garlic, onions and other foods regularly to repel mosquitoes. Because mosquitoes are insects with a keen sense of smell, the sour smell of human sweat often attracts them. In addition, the frequency of mosquito bites varies among people with different blood types, and generally women are more likely to be bitten than men.

7. Clean the gutters. The dark and humid kitchen sink is also one of the places that mosquitoes like very much. Especially the drain outlet that has been used for a long time will accumulate a lot of dirt, which is very disgusting. This is simply a paradise for mosquitoes. So what are some quick and effective ways to remove these disgusting dirt and prevent mosquitoes? Just put in a slice of lemon and add a few drops of vegetable oil.

How to kill mosquitoes most effectively when there are too many mosquitoes at home

8. Mosquito trap: The light will attract words, and when the words fly close, they will be electrocuted to death. This is a relatively healthy way to kill mosquitoes. There is a layer of faint light inside the mosquito trap, which mainly uses the mosquito's phototaxis and sensitivity to special wavelengths to lure mosquitoes to touch the net, and then the high voltage electricity instantly burns the mosquitoes. It is important to note that when using a mosquito trap, there should be no light in the room, otherwise it will affect the effectiveness of catching mosquitoes.

9. Electric mosquito coils. There are two types of mosquito coils: mosquito coils sheets and liquid electric mosquito coils. The first type of electric mosquito coil is to put pyrethrum and other insecticides into mosquito coils, and achieve the effect of killing mosquitoes by evaporating the smell after heating. If you add a few drops of essential oil, the effect will be better and usually last for 6-8 hours. But remember to replace the electric mosquito coils every day. The second type of liquid electric mosquito coil uses the capillary straw principle, continuously heats and releases insecticide, making it easy to use. Because a bottle of mosquito coil liquid can generally be used continuously for 30 days.

10. Mosquito coils. Mosquito coil advertisements on TV claim that they can kill mosquitoes, but this is not very credible. In fact, it doesn’t matter whether the mosquitoes die or not, as long as they don’t bother us. Therefore, mosquito coils can repel mosquitoes to a certain extent. However, hunger does not harm courage and anger, and there are always some words that are not afraid of mosquito coils.

11. Reduce sewage. This is the most fundamental way to reduce mosquitoes because mosquito larvae live in water, especially sewage. No sewage means mosquitoes will bite us to death.

12. Reduce plants. Female mosquitoes are bloodthirsty, but male mosquitoes are herbivores who feed on plant sap. Therefore, mosquitoes gather in places where vegetation is lush. Reducing vegetation can also be effective in eliminating mosquitoes.

13. Pay attention to cleaning every corner. Mosquitoes usually hide in cracks, so mosquito control agencies always spray more insecticide in these cracks when spraying pesticides. In addition, cleaning these areas more often can also effectively reduce mosquitoes. Of course, the most fundamental thing is to reduce nooks and crannies, buy seamless furniture, and fill up unnecessary gaps.
