Urban larval mosquito control strategies include elimination of aboveground water-holding containers by private residents (`source reduction') and larviciding of belowground storm drains and utility manholes. Effective source reduction is dependent on public education campaigns that identify key sources of mosquitoes, target at-risk neighborhoods, and create an informed and motivated citizenry. I conducted 242 yard surveys for mosquito larval habitats paired with Knowledge, Attitude, and Practice (KAP) questionnaires administered to residents in six socioeconomically-diverse neighborhoods in the greater Washington, D.C. metropolitan area, and sampled 201 belowground habitats adjacent to these households. In chapter 2, I analyze associations between resident socioeconomic status, knowledge, attitudes, practices and mosquito indices. In chapter 3, I examine variations in larval habitat quality, quantity and type across neighborhoods of differing socioeconomic status. In chapter 4, I compare larval populations in aboveground and belowground habitats. The implications for educational literature and mosquito management are discussed.
