West Nile Virus 2014

June 2014: Mosquito traps have been set throughout Larimer County. Mosquito numbers will continue to rise along with the temperatures. Weekly trap reports are now available.

Standing water from a wet spring and river runoff provides excellent breeding areas for mosquitoes. This is the time to eliminate standing water around your yard and property and stay clear of flooded and runoff areas.

Hot weather and moist conditions can result in explosive growth in mosquito numbers. As the number of infected mosquitoes grows, so does your risk of being infected with West Nile virus. Though rising, the risk of being bitten by a mosquito carrying West Nile virus and the numbers of infected culex mosquitoes is low at this time (June 6).

Now is the time to avoid exposure to biting mosquitoes and to wear repellent when outdoors! Be sure the repellent you use is effective against culex mosquitoes, the kind that carry West Nile virus. Information on effective repellents and other ways you can avoid West Nile virus infection is available through links in the lower part of this page.
