What is the most dangerous animal on earth? Viper? Sharks? Crocodile? If the “annual number of people killed” to define “dangerous”, then, the correct answer is: mosquitoes. Mosquitoes kill far more than the number of other animals, worldwide, mosquitoes in five minutes to kill the number of humans than the number of sharks kill humans a year. Mosquitoes why so terrible? Because the mosquito bite is not only after the blood and an itchy red bag, they can carry a variety of terrible viruses, can spread and other dengue fever, B brain, malaria, yellow fever and many other diseases. Mosquito war, everywhere is the pit Summer is here again, a new round of human mosquito war again! About mosquito prevention and mosquito control methods, clean up stagnant water, clean up garbage, install mosquito nets and screens, wear light-colored clothes, long clothes and pants, reduce the evening when going out, the use of electric mosquito beat, etc. I believe we all have to understand, but when it comes to “mosquito repellent” products (painted on the body to drive away mosquitoes, not kill mosquitoes), here the pit is big! Every summer is a time when mosquito repellent products are hot, it turns out there are pits where there is interest! For example, the above similar mosquito repellent water advertising all over the place, claiming “natural plant formula”, claiming “no pesticides”, claiming “plant essential oils”, each one is just what parents want! The reason is that many parents are misled to believe that “natural” is good, “plant” is safe, and “pesticide” ingredients are dangerous. …… but in fact, natural is not necessarily effective, many businesses so-called “natural formula”, “mosquito repellent package” does not have a substantial mosquito repellent effect, and may even be harmful Many plant ingredients have not been fully verified, and its safety is not well understood. The so-called “natural”, “plant” is just a selling point of the business. More frightening than mosquitoes is the interest behind the …… of course, if there are scientifically proven safe and effective plant ingredients, we certainly welcome. Reliable mosquito repellent products are which break the “natural” “plant” advertising gimmicks, to see what scientifically proven, authoritative agencies recommended mosquito repellent ingredients? The U.S. Food and Drug Administration (FDA) and the Centers for Disease Control and Prevention (CDC) recommend the following ingredients of mosquito repellent products: 1, mosquito repellent (DEET) 2, ecaridin (that is, picaridin, Icaridin / picaridin) 3, repellent ester (IR3535) 4, oil of lemon eucalyptus (oil of lemon eucalyptus) These repellent Ingredients have been registered in the United States Environmental Protection Agency (EPA), safety and effectiveness has been confirmed. The Canadian Academy of Pediatrics highlights the first two repellent ingredients: mosquito repellent amine, ecaritin (the American Academy of Dermatology also believes that these two are the best repellent), both of which are effective against ticks and mosquitoes. Here we briefly understand these effective mosquito repellent ingredients: 1, mosquito repellent DEET. mosquito repellent is the earliest use, the most research, the most brands are also the most classic repellent, safe and effective to use. As long as you buy regular products, according to the instructions for correct use, will not bring safety hazards, but to prevent the entrance into the eyes and so on. Recommended concentration of 10-30%, the higher the concentration, the longer the duration of the repellent effect, 24% DEET products can last for 5 hours, 10% DEET products to maintain the effect of mosquito repellent 1-2 hours. Children are not recommended to use products with a concentration higher than 30%, the concentration of DEET above 30% can not provide additional protection, and the concentration is too high may have some toxic effects. The younger the child the more recommended to use the lower concentration of the product, and minimize the number of spraying. 2.Ecateride, repellent ester. 7.5% of repellent ester has 2 hours of repellent effect, 10% of ecateride has 6 hours of repellent effect. Both Ekateride and repellent esters are regarded as alternatives to DEET, safe and low toxicity, especially Ekateride. So you can also choose the mosquito repellent containing ecarretin, but the American Academy of Pediatrics that although ecarretin is considered effective and safe, but there is a lack of adequate long-term follow-up research data, further follow-up studies are needed. 3, lemon eucalyptus oil. Oil of lemon eucalyptus is a plant-derived ingredients, with a certain effect of mosquito repellent, the effect is similar to 10% DEET, 1-2 hours. But the American Academy of Pediatrics and the CDC do not recommend the use of lemon eucalyptus for children under 3 years of age, pure lemon eucalyptus essential oil can not be used directly on the skin. Because lemon eucalyptus is a plant source, some lemon eucalyptus as the main active ingredient of mosquito repellent products by many businesses advocate “natural” “pure plant” “pesticide-free”, as if advanced Like a lot, a lot of advertising offensive, but in fact the vast majority of synthetic, and he will not tell you that under the age of three is not recommended for use. So parents must pay attention to it, the time to test the IQ, when buying mosquito repellent products must carefully check the instructions to understand the type and concentration of its active ingredients. How to correctly use mosquito repellent products 1, small babies (under 6 months, especially under 2 months) is not recommended to use mosquito repellent, physical mosquito prevention (mosquito nets, etc.). 2, the first time to use in a small trial to see if there is an allergic reaction. 3.Avoid using it on wounds, sunburns, rashes and allergy-prone skin. 4, avoid contact with the eyes and mouth; mosquito repellent spray products if you want to use the face, first sprayed on the hands and then wipe to the face, wash your hands after application. Avoid contact with children or accidental ingestion, not to children sprayed on the hands to avoid accidentally into the mouth. 5, back indoors to clean off the residual solution or take a shower, sprayed mosquito repellent clothes to wash clean and then wear. 6, mosquito repellent can only be sprayed on clothing and exposed skin, can not be sprayed on the skin covered by clothing. 7, the younger the child the more recommended to use low concentration of products, minimize the number of spraying, not too frequent spraying. 8, some mosquito repellents contain “permethrin” ingredients, can only be sprayed on clothes, not on the skin.
