As the saying goes, 'Kill mosquitoes early in spring and be bitten less in summer.' What should citizens do now to prevent mosquito breeding and bites? Kang Min, director of the Infectious Disease Prevention and Control Institute of the Guangdong Provincial Center for Disease Control and Prevention, stated on the 18th that spring is a critical period for mosquito breeding and the best time to prevent them. According to the Guangdong Provincial Center for Disease Control and Prevention, in the 10th week of 2025 (from March 3 to March 9), there was one new reported case of dengue fever in the province, which was an imported case reported by Guangzhou city (based on current address statistics). Mosquitoes, seemingly insignificant insects, are a major threat to human health. In China, mosquito borne diseases such as dengue fever, Japanese encephalitis, and malaria (in localized areas) still pose a threat to public health security. Mosquitoes need water to grow, and they also spread diseases when they bite us. We have found that there are more mosquitoes around us now, because the temperature has risen and mosquitoes that hide in winter have become more active. They wait for opportunities to bite and suck blood, store nutrients, and breed offspring. At the same time, they are also searching for water bodies to lay eggs Kang Min said that the increase in rainfall in spring leads to the formation of stagnant water, which provides mosquitoes with ample opportunities for reproduction. Mosquitoes reproduce rapidly, for example, disposable plastic lunch boxes discarded outdoors may breed thousands of mosquito larvae. If effective mosquito prevention and control measures are not taken in a timely manner, it will be difficult to control mosquito density in summer, and the risk of transmission of mosquito borne infectious diseases such as dengue fever will also greatly increase. How to scientifically and effectively prevent and control mosquitoes in spring? Kang Min mentioned clearing the accumulated water. The eggs and larvae laid by mosquitoes live in water, and without water, the larvae cannot transform into mosquitoes. Therefore, removing stagnant water is the key to mosquito control. Many citizens like to keep aquatic plants at home, and these containers are very attractive to mosquitoes for laying eggs. We can use mosquito proof containers, change the water once a week and rinse thoroughly to prevent mosquito breeding. In addition, clean regularly. Adult mosquitoes usually prefer dark and damp places. They can use electric mosquito swatters to "patrol" the areas near the bathroom and kitchen sewers. At home, they can search for items that are not frequently moved and use tools such as electric mosquito swatters to kill adult mosquitoes hiding in various places. Except for the colder winter and early spring seasons in Guangdong, other times are the season when mosquitoes and insects are active. You can install screen windows at home and close them in a timely manner when entering or leaving to prevent mosquitoes and insects from entering the room. Kang Min said that in addition, mosquito nets, electric mosquito repellent liquid, etc. can also be used to prevent mosquito bites at night. Kang Min reminds us that it is currently a good season for spring and flowers to bloom. Schools and units organize spring outings. When outdoor activities, everyone should apply mosquito repellent, wear long clothes and pants, avoid staying in green belts for a long time, and prevent mosquito bites. (New Society)
