Species of Culex can be found throughout the globe, except at the extreme northern latitudes. Depending on the region and species, Culex mosquitoes can carry a wide array of public health threats.
Culex mosquitoes breed in various types of stagnant water. Preferred oviposition habitats such as rainwater barrels, catch basins, storm drains, and septic tanks are rich in organic material. Eggs are laid in raft-shaped batches on the water surface.

While Culex will lay their eggs in a variety of standing waters, these habitats can typically be categorized into four ecotypes:
Sewage Systems
- General description: These highly polluted habitats contain sewage or mixed sewage and rainwater. These habitats include cess pits, septic ditches, septic tanks, and blocked sewerage systems.
- Key sewage system Culex include:
Container Sources
- General description: These habitats are generally man-made sources that will catch and hold water, such as waste tires, buckets, and rain barrels.
- Key container Culex include:
Drainage Systems
- General description: These habitats include catch basins, channels, roadside ditches, and underground storm water/drainage systems.
- Key drainage system Culex mosquitoes include:
Open Habitats
- General Description: Surface-water habitats that become stagnant and enriched to support Culex larval development, such as swamps, marshes, bogs, rice fields, and pastures.
- Common open habitat Culex mosquitoes include:
