What Drives Mosquito Activity in Seattle?

Several factors influence mosquito populations in Seattle, including weather, standing water, and urban green spaces. The city's frequent spring rains and mild summers create perfect breeding grounds, especially near wetlands like the Union Bay Natural Area. Key influences include:

Vegetation: Dense foliage offers resting spots.
