Are There Mosquitoes in Denver? A Comprehensive Guide
Yes, mosquitoes are present in Denver, Colorado. While Denver’s semi-arid climate isn’t ideal for large mosquito populations, these insects thrive in areas with standing water, especially during the warmer months.

Mosquito Habitats in and Around Denver
Despite Denver’s dryness, mosquitoes find breeding grounds in various locations:
- Standing Water: This is the primary breeding site. Even small amounts of water in containers, bird baths, clogged gutters, or puddles can support mosquito larvae.
- Irrigation Systems: Parks, golf courses, and residential lawns with irrigation systems provide ample moisture for mosquito breeding.
- Natural Water Sources: Ponds, lakes, and rivers, especially those with stagnant areas or vegetation, also contribute to mosquito populations.
- Low-lying Areas: Areas that collect rainwater, even temporarily, can become mosquito breeding sites.
Mosquito Species in Denver
Several species of mosquitoes are found in the Denver area. Common species include Culex mosquitoes, which can transmit diseases like West Nile virus. Other species may be nuisance biters, causing itchy welts but posing less of a health risk. The Mosquito page on Wikipedia gives detailed information about the different types of mosquitoes.
