West Nile virus (WNv) is expected to arrive in British Columbia in the near future. In preparation for its arrival, larval mosquito control (including catch basin treatment) has been performed to reduce the vector mosquito population (specifically Culex pipiens). GPS coordinates of catch basin treatments and adult mosquito traps are collected by several collaborating organizations, and mapped to an interactive WNv mapping system. This allowed us to group the catch basin treatments within three kilometers of mosquito traps. An increase in catch basin treatment around a trap is expected to reduce the adult Culex pipiens caught. Other factors were also considered including climate, larval habitat, and treatment products. The results of this analysis, enabled by GIS technology and spatial data, are useful in understanding the dynamics of the Culex pipiens species and can be applied to improve larval control measures in the future.
