Overview
- Experts warned this week that a shift to warm days with intermittent rain has created near‑ideal conditions for rapid mosquito breeding, with peak activity expected in August and September.
- The invasive Asiatic tiger mosquito has been detected in parts of Hesse and Bavaria and is expanding its range inside Germany, using tiny water collections such as plant saucers and bird baths to lay eggs.
- At about 30°C mosquito development is fast: common house mosquitoes can mature in seven to ten days and tiger mosquitoes in five to seven days, enabling quick multi‑generation population growth.
- Public‑health agencies emphasize simple household actions — empty or cover rain barrels, clean bird baths, dry plant saucers, fit window screens, and use repellents — and ask citizens to photograph or submit captured specimens to support mapping and response.
- The tiger mosquito was first recorded in Germany in 2007 and in Hesse in 2018; native mosquitoes already transmit West Nile virus locally and officials say the current weather raises the likelihood of more WNV infections this season.
