Mozzwise Briefing

Czechia has seasonal mosquito activity from May through September, with peak populations during the summer months. The Moravian lowlands, the Elbe and Vltava river valleys, and pond-rich areas of South Bohemia have the highest mosquito density. Prague experiences moderate summer nuisance biting near the river.

West Nile virus is the primary mosquito-borne disease concern, though cases are rare in Czechia. Overall mosquito-borne disease risk is very low. The continental climate limits the active season.

Culex pipiens is the dominant species. The extensive carp pond systems in South Bohemia and the Moravian lowlands support localized high-density summer populations.
