Increased Mosquito Activity Along the Yakima River

The Benton County Mosquito Control District has over the year's trapped 14 different species of mosquito (there are over 200 different species in the United States, and over 2,000 worldwide).  Each of these mosquito species have some similar characteristics but also some differences.  The Anopheles (genus) mosquito is a type that prefers cooler and cleaner water sources, often times with some degree of flow to it (most of our species prefer stagnant, highly organic water sources).  The Anopheles overwinter as adults and since they are not as affected by cooler temperatures can get an early start to the season. 

We are noticing increased activity along the Yakima River and much of this is the Anopheles mosquito.  Unfortunately, it is too cold for adulticiding measures (killing the adult, flying mosquito) and treatment of areas of water along the river is problematic or ineffective due to the flow.

We are checking and treating where we can, but we do not run a full crew year round, so we are presently at an extremely limited work staff but are bringing on seasonal postions starting April 1st.  We recommened that you try and avoid being outside during higher mosquito activity periods (dusk and dawn), if you choose to, then use a Centers for Disease Control approved repellent, and wear loose fitting long pants and shirts.  Should you have additional questions or concerns please reach out to use and we will do our best to assist you.

IPM is designed to utilize cost-effective control measures to reduce mosquito populations and the diseases they potentially carry, while being environmentally sensitive.

Communication and cooperation with property owners, residents and governmental agencies are critical components in the effort to reduce mosquito populations. Benton County MCD strives to be open and responsive to our community.
