Culex quinquefasciatus (also commonly known as the 'Southern house mosquito') is a widespread mosquito on mainland Australia that is of significant pest and public health concern. This species is not a severe biter but can cause a nuisance by being abundant in and around homes. It is not thought to play an important role in disease outbreaks but it may transmit a range of arboviruses. The mosquito is closely associated with freshwater environments, especially highly polluted stormwater and waste-water ponds and tanks.
