With the arrival of the mosquito active season, localities across China have launched mosquito prevention and control operations featuring refined, green, and smart measures, gradually forming a prevention and control structure led by the government, coordinated by departments, and involving public participation.

Hainan Province has registered and filed approximately 595,000 mosquito breeding corners across the province, and flexibly adjusts disinfection frequency based on mosquito density monitoring. In Yinggehai Town, Ledong Li Autonomous County, differentiated treatments are applied according to different types of water accumulation: residual spraying and mist machine penetration are used in thick vegetation areas, while specialized equipment is deployed near sewers. In Chongqing's Yuzhong District, rainwater outlets are dredged to prevent standing water, and small water accumulations are dealt with by turning over containers, removing, covering, or filling. In Fuzhou, Fujian Province, flower markets drain water from the leaf axils of plants such as plantains and traveler's trees by drilling holes, fill rock holes in rockeries and tree holes with lime-sand mixture, and adopt specific chopping methods for left-over bamboo tubes.

For water bodies in parks and landscape pools that cannot be drained, localities widely apply biological control or physical intervention. In Beijing's Tongzhou District, over 700,000 native fish fry including topmouth culter and bitterling were released into the North Canal to prey on mosquito larvae; Chaoyang Park and Zizhuyuan Park also released fish fry into landscape waters to “control mosquitoes with fish.” Shijiazhuang City enhances water flow by regulating river channel water levels during the flood season, eliminating conditions for mosquito breeding and egg-laying.

Public participation has become a key feature of the campaign. In Songgang Village, Qingxi Town, Dongguan City, a “Mosquito Snapshot” platform was launched, allowing villagers to take photos of water accumulation points and upload them; upon review, they can receive laundry detergent or red rice. The platform forms a closed loop of “upload photos – dispatch for disposal – rectification feedback – points redemption,” helping to fill gaps in mosquito control. Beijing issued the Three-Year Action Plan for Mosquito Prevention and Control (2026-2028), requiring multi-channel publicity of mosquito prevention knowledge and guiding the public to establish hygiene and disease prevention awareness. Shanghai launched a summer-and-autumn “National Mosquito Prevention” campaign, rolling out citywide intensive control actions every 10–14 days, and releasing public service short videos and health bulletins. The Guangzhou CDC developed a mosquito larvae prevention flowerpot tray with a double-layer design that channels seepage water from potted plants into a closed lower storage space, preventing mosquitoes from accessing water to lay eggs.

High-tech means have been widely applied. In Xihu District, Hangzhou, 55 “Sky-Eating Frog” intelligent breathing mosquito traps were deployed in Shizikou Park; the device concentrates carbon dioxide to 6–7 times the concentration of human exhalation and uses customized light spectra to lure mosquitoes, with each unit covering 50–100 square meters. Sichuan's first intelligent mosquito vector monitoring system was put into operation in Mianyang, capable of real-time collection of mosquito density, species composition, and activity patterns, shifting from passive response to active early warning. In Guangzhou's Huangpu District, the “mosquito factory” Guangzhou Weibaikun Biotechnology Co., Ltd. produces 5 million sterile male mosquitoes per week; these males mate with wild females and produce eggs that do not hatch. The “mosquito vs. mosquito” technique has been tested in multiple regions nationwide, significantly reducing wild mosquito density.
