What Influences Mosquito Activity in St. Moritz?

Several factors influence mosquito prevalence in St. Moritz. The combination of altitude (about 1,800 meters) and alpine weather creates a shorter mosquito season compared to lowland regions. Key influencers include:

Temperature: Warmer days accelerate mosquito breeding.
Water sources: Standing water from melting snow and lakes provides breeding grounds.
Vegetation: Dense forests around the valley shelter mosquitoes.

Additionally, the Engadin valley's unique microclimate can cause variability in mosquito numbers year to year. For detailed environmental data, visit the Swiss Federal Institute for Forest, Snow and Landscape Research. Understanding these factors helps locals and visitors minimize exposure.
