Culiseta is found throughout the world. Most species are cold-adapted, meaning they occur mainly at elevations or during cooler parts of the year. Culiseta feed primarily on birds and mammals. A few feed on reptiles, and several species attack domestic animals and humans.

The larvae of most species are found in ground waters such as bogs, marshes, ponds, streams, ditches, and rock pools.
