Can Mosquitoes Survive Colorado's Elevation and Climate?

Can Mosquitoes Survive Colorado's Elevation and Climate?

Colorado is like a different world from the rest of the country. For newcomers, it can feel like living in a snowglobe in certain areas when you’re surrounded by snow-tipped mountains. And if you’re new to the elevation, well, get ready, because even a short walk in those higher-elevation spots can have you panting. 

Even though Denver-area residents are used to the thinner air we have up here, many take it a step further and assume that Colorado's mile-high elevation and semi-arid climate mean mosquitoes are not a problem. While it’d be nice if it were true, this is a total misconception. 

Debunking the Popular Belief About Mosquitoes in High-Elevation Colorado Areas

Sure, Colorado’s elevation can be difficult for both newbies and longtime residents. But this doesn’t mean pests like mosquitoes have the same struggles. In fact, mosquitoes thrive in the Denver metro area, especially during the compressed season from June through September. And since mosquitoes breed in water (as little as a capful), the snowmelt from the Front Range feeds rivers, creeks, and irrigation canals and creates abundant breeding habitats.

Denver's many parks, greenbelts, and stormwater retention features also provide standing water for breeding, and many of the mosquitoes that come from these areas are specifically adapted to these mountainous and high-alpine environments. The only effect the elevation really has is that it shortens the season, but this also means the mosquito season here in CO is much more intense. 

What You Can Do to Help Keep Mosquitoes Away

Colorado consistently reports West Nile virus cases, primarily transmitted by Culex mosquitoes that are well-adapted to the region. For this reason, it’s important to take measures to help reduce mosquito populations and the spread of harmful mosquito-borne illnesses. 

Here are a few steps we recommend:

  • Use outdoor fans to disrupt their flight patterns (mosquitoes are weak fliers). 
  • Wear long, loose clothing. 
  • Avoid spending time outdoors during dusk and dawn. 
  • Remove stagnant or standing water in your yard. 
  • Work with a professional pest control company on mosquito control in Colorado.
