Factors Driving Mosquito Activity in St. Catharines

Several factors influence mosquito populations in St. Catharines. Warm temperatures and standing water from rain or irrigation create perfect breeding conditions. The region's humid climate, coupled with lush parks like Montebello Park and the nearby wetlands, supports mosquito proliferation. Additionally, urban development can sometimes increase stagnant water spots, such as clogged gutters or abandoned pools. Key influences include:
  • Seasonal weather patterns
  • Local water bodies and wetlands
  • Human-made water collections
By understanding these factors, residents can take simple steps to reduce mosquito habitats around their homes. Learn more about mosquito ecology at Public Health Ontario.
