Tiger mosquito spread in Central Europe

Overview

In late July 2026 German researchers documented a sharp rise in Aedes albopictus numbers across southern Germany and urged removal of breeding sites and use of insecticide‑free traps, warning that the mosquito could carry chikungunya northward. Within days 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, reinforcing public‑health concerns.

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, conducted door‑to‑door inspections and urged residents to regularly empty containers that hold water, citing transport of goods or travelers as the likely introduction route.
