Asian tiger mosquito expansion in Central Europe and the Low

Overview

In late July 2026, German researchers documented a sharp rise in Aedes albopictus numbers across southern Germany, warning that the mosquito could carry chikungunya northward. Danish scientists reported the species moving toward Denmark, noting the concurrent appearance of a non-vector “cemetery mosquito” and stressing the need to eliminate standing water to limit dengue-risk tiger mosquitoes. On 31 July, entomologist René Bødker warned that the cemetery mosquito could arrive in Denmark as early as the next day, possibly via a camping caravan, while the tiger mosquito continued its northward advance. A week later, officials in Lower Saxony confirmed the first breeding population of the Asian tiger mosquito in Hannover-Döhren, the northernmost established site in Germany. Although no pathogens were detected, authorities installed traps and conducted door-to-door inspections. By mid-August, the species' presence was noted in other regions. In Vienna, where the mosquito has been established since 2021, experts from AGES noted that while the risk of transmitting tropical viruses remains low, the mosquitoes are highly active. Unlike Graz, which uses sterilized males for birth control, Vienna has no plans for large-scale eradication. In Friedrichshafen, Germany, sightings in the Zeppelindorf area prompted local authorities to urge citizens to clear gutters and cover rain barrels. In response to the ongoing expansion, health authorities in Austria and Germany have increased monitoring. In Bavaria, Minister Judith Gerlach issued warnings as authorities identified overwintering-capable populations in Fürth, Würzburg, and Munich, following reports in Nuremberg and surrounding districts. In Austria, monitoring continues in Carinthia, where individual detections were noted in Villach and Klagenfurt. In late August, the Netherlands Food and Consumer Product Safety Authority (NVWA) detected the species in Uden, implementing control measures such as larva-killing agents and mosquito traps. By mid-September, health authorities in Belgium and the Netherlands expanded their monitoring efforts.
