Factors Driving Mosquito Activity in Santa Rosa

Several environmental and human factors influence mosquito populations in Santa Rosa. The region's Mediterranean climate—with wet winters and dry summers—creates ideal breeding conditions especially after spring rains. Key influences include:

Standing water in garden ponds or clogged gutters
Warm temperatures that accelerate mosquito life cycles
Proximity to natural wetlands and riverbanks

Additionally, urban development near Sonoma County’s waterways can increase mosquito habitats. Understanding these factors can help residents reduce breeding sites around homes. For more details, visit the Sonoma County Vector Control website.

Protecting yourself involves:
