Mosquito Control Continues to Protect Public Health During Coronavirus Outbreak

The Cowlitz County Mosquito Control District is committed to protecting public health. The District is taking proactive steps in order to protect staff and residents to help slow the spread of COVID-19. However, the current preventative measures to contain the spread of coronavirus will not hinder performance of essential mosquito control activities in Cowlitz County.  The District will continue to provide essential Mosquito Control service such as mosquito inspections, surveillance and control to prevent mosquito transmitted diseases. Mosquito bites can not transmit COVID-19 however they can transmit several other diseases including West Nile Virus.  Despite the emphasis on COVID-19, we can’t lose sight of the fact that other debilitating and potentially fatal diseases transmitted by mosquitoes may also potentially infect our citizens. 

As a protective measure, we are closing our offices to the public, however service requests can be submitted online at or by calling the Mosquito Control Hotline at 360-425-5658

While organized mosquito control activities are vital to reducing human-mosquito contact, don’t forget the importance of public action. The general public can make substantial contributions to their own safety by following “the 3 D’s”:

•             Drain:    Empty out water containers at least once per week

•             Dress:  Wear long sleeves, long pants, and light-colored, loose-fitting clothing

•             Defend:  Properly apply an approved repellent such as DEET, picaridin, IR3535, oil of lemon-eucalyptus or any other EPA-registered repellent.

We will continue to monitor, assess and adjust our operations as conditions change. We encourage you to follow the CDC and your local public health department guidelines about slowing the spread of COVID-19.
