有害生物防治业（PCO）近年来在我国发展迅猛，从日常的除虫服务到卫生城市和卫生县城的创建，均离不开PCO公司的参与。而地震、泥石流以及洪涝灾害发生后往往需要在短时间内开展有效的卫生防疫工作，PCO公司既有公益热情和社会责任心，又有消毒杀虫现场经验，应正确引导和发挥他们在灾后防疫中的积极作用，为保障灾区居民身体健康服务。

During recent years, pest control operations (PCO) have been growing rapidly in China. Participation of PCOs is needed in daily pest control services and establishment of hygienic city. Following disasters such as earthquake, land slide, flood, etc., effective epidemic preventions are crucial, which must be launched in a timely manner. PCO companies are passionate in public services and social responsibility, and are experienced in field disinfection and insecticide application. Therefore, PCOs should be encouraged and guided to play a positive role in disease control services in disaster areas.
