1, DEET mosquito killer is safer.
According to BBC News, British scientists claim that insect repellent containing DEET can be used safely. DEET can prevent malaria and dengue fever spread by mosquitoes and other insects.
Some people worry that DEET may be toxic and pose a threat to health. But scientists at the London School of Hygiene and Tropical Medicine say DEET is "the safest mosquito repellent product you can get". They suggest that when you are in some tropical areas and countries where diseases are easily spread by insects, it is best to use mosquito repellent containing 20-50% DEET on your skin.
From 2002 to 20 12, the number of British people going to tropical countries increased by 2 million. The Ministry of Public Health in England recently warned that the incidence of dengue fever brought by returning tourists is increasing. With the increasing popularity of foreign tourism, it is necessary to raise awareness of the risk of mosquito bites.
DEET was developed by USDA on 1946. It was used exclusively by the US military in the field, and 1957 began to enter civilian products.
In the past, people's concerns about the safety of DEET mainly came from the news reports that the incidence of encephalopathy in children who used DEET increased greatly in the11980 s and the brain swelled. However, scientists at the London School of Hygiene and Tropical Medicine believe that the role of DEET in these deaths is "purely accidental" and probably caused by taking other drugs at the same time. After trawling through all kinds of effective medical literature, they came to the conclusion that since 1957, there have been only 14 cases of brain diseases related to DEET, and worldwide, 200 million cases are related to other insect repellents every year.
At the same time, they suggested using DEET instead of changing diet. There is no evidence that eating yeast sauce and garlic can effectively prevent mosquitoes.
Lead researcher Dr. James Logan said that there are always many "rumors" about DEET, and they are always "confused" with DDT, an insecticide used to kill insects. Steve Lindsay, an independent expert professor at Durham University, also agreed to change the findings of this study.
Knowledge expansion:
1, what is DEET?
DEET (N, N- diethyl m-toluamide), also known as DEET and DEET, is the best mosquito repellent. DEET can effectively prevent mosquitoes, ticks, chigger mites, fleas and flies.
2. Is DEET safe for children or babies?
According to the Centers for Disease Control and Prevention, DEET is safe for children and infants over 2 months old. According to the regulations of American Academy of Pediatrics, mosquito repellent used by children should not contain more than 30% DEET. There is no evidence that children who use DEET according to the instructions will have serious diseases. But once you touch the wound, it's best to wash it with soap and water.
2. Anti-mosquito methods at home
1. Use mosquito nets and screens.
If there are many mosquitoes in summer, mosquito nets and screens can be used to prevent mosquitoes. In addition, you can sprinkle some cool oil on the mosquito net to prevent mosquitoes from staying on the mosquito net.
2. Use mosquito-repellent incense and mosquito-repellent water
If there are many mosquitoes in summer, mosquito-repellent incense and mosquito-repellent water can be used to kill mosquitoes. Attention should be paid to lighting mosquito-repellent incense where there are no flammable materials to avoid other accidents.
3. Open doors and windows as little as possible.
If there are many mosquitoes in summer, try to reduce the frequency of opening doors and windows to avoid mosquitoes with doors and windows open entering the room. Of course, it is also necessary to ventilate the room regularly to avoid indoor air pollution.
Step 4 eat garlic to prevent mosquitoes
Mosquitoes can eat garlic to prevent mosquitoes in summer. After eating garlic, people's skin secretions will contain garlic, which is very annoying to mosquitoes. People who often eat garlic are not easy to be bitten by mosquitoes. Mosquito killing water contains more chemical components. Don't spray it on people.
5, vitamin B 1 mosquito control
In summer, many mosquitoes can use vitamin B 1 to prevent mosquitoes. Take vitamin B/KLOC-0 orally/or wipe your body with vitamin B 1 when taking a bath. Because the pungent smell contained in vitamin B 1 is unbearable for mosquitoes, it can help prevent mosquitoes.
6, toilet water bath mosquito killing
If there are many mosquitoes in summer, you can take a bath with toilet water to prevent mosquitoes. The ingredients contained in the toilet water can effectively help prevent mosquito bites. In addition, the unique youthful fragrance of toilet water also helps to better remove the sweat smell on the body.
7, smoked wormwood mosquito control
If there are many mosquitoes in summer, you can fumigate them with wormwood. Fumigated wormwood can give off a special smell to drive away mosquitoes and help sterilize.
Mosquito is a very annoying insect, because it will bite our skin, causing redness, itching and bagging. Some people will also have an immune response to mosquito bites, which will cause many wheals on your skin. Mosquitoes are hard to kill, but we can follow the above methods to prevent mosquito bites.
