Not only a nuisance, mosquitoes can pose a serious health threat to people. Disease can be spread to people through the bite of an infected mosquito. Over 40 different mosquito species can be found in Washington, and many are vectors for diseases, such as West Nile virus, western equine encephalitis, and St. Louis encephalitis.
In Cowlitz County it is the Cowlitz County Mosquito Control District that works to keep mosquito populations at a reduced level. Please visit their website for a list of services they provide.
