Why Mosquitoes Thrive in Waterloo

Several factors influence mosquito activity in Waterloo. Warm temperatures and standing water from frequent spring rains create ideal breeding grounds. The region's many parks and wetlands, like the rare Carolinian forest remnants, provide perfect habitats. Here are key contributors:

Seasonal rainfall patterns
Local water bodies such as rivers and ponds
Urban green spaces and shaded areas

Additionally, the microclimate around the Grand River can increase humidity, further supporting mosquito populations. Understanding these helps locals and visitors anticipate mosquito presence and take preventive measures.
