Mosquito survival patterns in Northern Colorado

Mosquito populations in Northern Colorado are significantly impacted by temperature changes, though they do not disappear entirely. According to Colorado State University, mosquitoes struggle to fly when temperatures drop below fifty degrees, and the first freezes in September and October typically thin out populations.

However, various mosquito species in the region have different survival mechanisms. Some can survive the winter by finding sheltered spots, meaning the pests may persist year-round. Additionally, the risk of West Nile Virus remains a concern in Colorado, peaking in July and August but often lingering into the fall.
