The upper tidal reaches of the various arms of Ludmilla Creek in Darwin have been historical breeding sites for pest and disease carrying mosquitoes. Most of the historical mosquito breeding in the Ludmilla Creek catchment was a direct result of urban development and associated stormwater discharge. The major mosquito breeding sites associated with Ludmilla Creek were targeted in 1984 under the combined Northern Territory Government and Darwin City Council mosquito engineering program, which was supervised by Medical Entomology. These included constructing suitable drains in the Coconut Grove, Fannie Bay and East Point areas of Ludmilla Creek.
