Mosquito season has begun in Denver, and local environmental health crews have started testing mosquitoes across the city for disease last July 1, 2015. In a wet spring season like the one recently experienced by Colorado’s most populous region, water can start reaching places it doesn’t usually reach, giving mosquito eggs the amount of moisture they need to hatch. Crews will sample mosquitoes from 50 sites around the city. High mosquito populations will be tested for the presence of West Nile Virus (WNV), and then treated with an all-natural larvicide to try to contain their numbers.
