Factors Affecting Mosquito Activity in Leiden

Several factors influence mosquito presence in Leiden, including weather conditions, water sources, and urban greenery. The city’s many canals and nearby wetlands provide ideal breeding sites for mosquitoes. Warm temperatures and humidity boost their activity, especially during summer. Here's what impacts mosquito populations:
  • Standing water in canals and ponds
  • Warm, humid weather
  • Vegetation density around parks and gardens
Understanding these can help you reduce exposure. For example, wearing light-colored clothing and using insect repellent when strolling near the famous Leiden Botanical Garden can make a difference. Check local weather forecasts alongside the mosquito forecast for a comprehensive view.
