河滨市西区凌晨喷药灭蚊：因应西尼罗河病毒，超低容量喷洒覆盖市中心以西街区
加利福尼亚州河滨县河滨市的居民请注意：西北蚊虫与病媒防控区（Northwest Mosquito and Vector Control District）宣布，将在凌晨3时至6时对市中心以西一片街区实施超低容量喷药灭蚊，作业时段经过重新排定，以因应当地检出西尼罗河病毒。
此次喷洒范围西至 Carlo Drive、东至 Brockton Avenue、北至 Cover Street、南至 Luther Street。防控区表示，超低容量喷洒使用极低剂量的杀虫剂在空气中形成细雾，专杀飞行中的成蚊；作业安排在凌晨行人与宠物最少的时段，居民在喷洒时及过后短时间内留在室内、关好门窗即可。河滨县今年已报告四例人类西尼罗河病毒感染病例。
防控区提醒，本地蚊虫季为5月至10月，居民应清除家中积水容器、给门窗装好纱窗，外出时使用驱蚊剂。喷药安排如因天气调整，将在该区网站 northwestmvcd.org 更新，咨询电话为 951-340-9792。
Overnight Mosquito Spraying in West Riverside as District Responds to West Nile Virus
Residents of the City of Riverside, in Riverside County, California, should take note: the Northwest Mosquito and Vector Control District has scheduled an ultra-low-volume mosquito treatment between 3 a.m. and 6 a.m. for a neighborhood west of downtown, in an operation rescheduled in response to West Nile virus detected in the area.
The treatment area is bounded by Carlo Drive to the west, Brockton Avenue to the east, Cover Street to the north and Luther Street to the south. The district said ultra-low-volume spraying releases a very small amount of insecticide as a fine mist that targets flying adult mosquitoes, and the overnight timing is chosen when few people and pets are outdoors; residents should simply stay inside with doors and windows closed during the spraying and for a short time afterward. Riverside County has reported four human West Nile virus infections in 2026.
The district reminded residents that local mosquito season runs from May through October, and urged them to drain standing water around their homes, keep window and door screens in good repair, and use repellent outdoors. Weather-related changes to the spraying schedule will be posted at northwestmvcd.org, and the district can be reached at 951-340-9792.
