This species is native to Europe and is predominantly found in coastal regions.

[1] It is especially abundant in marshlands where it often represents the majority of mosquito populations sampled.

[2] Aedes detritus is primarily found in coastal salt marshes but can also inhabit brackish water pools.

Occasionally, freshwater streams near marshes may dilute salinity, allowing for mixed populations with other mosquito species such as Aedes caspius.

[3] While there is limited specific information on the vector capacity of Aedes detritus, it has been shown that this species has the potential to be a competent vector of Japanese encephalitis virus.
