Mosquito plague threatens Lake Ammersee: residents are desperate!
In the Oberland, the mosquito plague is again a hot topic, especially around Lake Ammersee. While flooding last year caused a veritable invasion of these pests, the situation so far this year looks encouraging. Rainer Jünger, from the “Mückenplage Nein Dank” association, stated that as of today, July 10, 2025, no flood has occurred and the mosquito plague has therefore largely disappeared. However, this could change quickly if floods occur and the water remains standing for longer, as the larvae of flood mosquitoes hatch in pools created by floods, as Radio Oberland reports.
In the neighboring town of Eching am Ammersee, however, the mosquito situation is already critical. Residents there report massive mosquito plagues, which are encouraged by a high groundwater level and damp meadows. Daniela Krüger, a resident, complains about swollen mosquito bites and difficulty using her garden. The situation is so tense that even public events such as the midsummer bonfire had to be canceled because of the mosquitoes. The catering industry is also suffering, as fewer guests want to sit outdoors, as Merkur reports.
Measures against the plague
Residents are calling for urgent action to combat mosquitoes. Rainer Jünger emphasizes that the use of the biological agent BTI is necessary to combat mosquito larvae. This product kills mosquito larvae without harming other insects. His demand was met with approval: in Eching, almost 80% of those entitled to vote were in favor of the use of BTI, but no corresponding measures were taken. The community has so far failed to take action here, which Jünger sees as a big problem. Using mosquito sprays could also leave chemical residues in the water, raising additional concerns.
Demand for mosquito repellents at local pharmacies has already increased and many products are sold out. Pharmacists report very swollen mosquito bites on their customers, especially children. Experts expect that the mosquito plague could last until September, depending on weather conditions, as also mentioned in the Merkur article.
So what is the best way to protect yourself from mosquitoes? Some experts recommend preventative mosquito control measures that should be taken during flood events. Early control of the larvae and the use of biological agents can help prevent more massive plagues. Such strategies are crucial in order to be able to enjoy undisturbed summer evenings in the future, as explained on KKM insect and vermin protection.
It remains to be seen how the mosquito situation will develop in the coming weeks. Movement in communities could be crucial to bringing the mosquito plague under control in a timely manner and allowing residents to spend time outdoors undisturbed again.
