Given the long term use of automobiles in the United States there are likely to be effects of salt and petroleum in the water bodies found in roadside ditches that provide habitats for larval mosquitoes. Mosquitoes are especially resilient against pollutants which may boost their populations. There may be unintended consequences of roadway pollution to these habitats, which may also have implications for human health via the transmission of West Nile Virus, EEE, and St. Louis Encephalitis.
