Mosquito Control

Currently, the risk of West Nile virus (WNV) infection is rated at level 1 (Low Risk). Larval control operations are ongoing in wetland and irrigated locations in and around Laramie. Adult mosquitoes numbers are forecasted to remain high throughout July. Numerous afternoon and evening thunderstorms will hamper adult mosquito treatments as conditions must be above 55° F to get effective control on adult mosquitoes and wind speeds need to be between 1 mph and 10 mph with no precipitation. Crews will be out treating for adult mosquitoes Sunday evenings through Thursday evenings as conditions allow.

Seventy six mosquito samples have been tested for West Nile virus so far this season. Three (3) mosquito samples (out of 76) have tested positive for West Nile virus in 2019 as of 8/15/2019.

Illnesses on the rise (CDC)

 Almost everyone has been bitten by a mosquito, tick, or flea. These can be vectors for spreading pathogens (germs). A person who gets bitten by a vector and gets sick has a vector-borne disease, like dengue, Zika, Lyme, or plague. Between 2004 and 2016, more than 640,000 cases of these diseases were reported, and 9 new germs spread by bites from infected mosquitoes and ticks were discovered or introduced in the US. State and local health departments and vector control organizations are the nation’s main defense against this increasing threat. Yet, 84% of local vector control organizations lack at least 1 of 5 core vector control competencies. Better control of mosquitoes and ticks is needed to protect people from these costly and deadly diseases.
