Thank you for visiting the Website for the Benton County Mosquito Control District. Since 1969 we have been providing mosquito control services. We hope that this website answers your questions and increases your knowledge of mosquitoes and mosquito control activities. If you can't find what you're looking for, please feel free to contact us.
The Benton County Mosquito Control District is dedicated to responsibly improving the quality of life and increasing public education in our area. The District accomplishes this by utilizing Integrated Pest Management (IPM) strategies. 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.
West Nile virus Detected in Multiple Areas
The District has detected the presence of the West Nile virus (WNV) in a samples of collected mosquitoes from multiple locations; Benton City, Kennewick, Richland, West Richland, and Mabton. Please note that just becaue we have not detected WNV in mosquitoes in an area does NOT mean that the virus is not present. Given the number of locations that the virus has been detected and the time of year (August is statistically a higher month for disease transmission with mosquitoes), the District is asking everyone to be aware, not alarmed, and to take reasonable precautions to minimize exposure to mosquitoes.
We routinely monitor areas within the District boundaries in an effort to detect WNV in the mosquito populations so that we can focus our efforts to specific areas with the goal of reducing mosquito populations and minimizing the potential impact upon people, pets, and livestock. The District wants to remind everyone in our District to (1) use repellent according to label and when appropriate, (2) avoid areas and times of higher mosquito activity, and (3) Tip n' Toss any water holding containers at least once per week.
The District has a map that shows sections (1 square mile) that has confirmed West Nile virus activity. This does NOT mean that other areas do not have WNV; the District cannot sample all areas. WNV Map
The heat is on!
As temperatures warm up, the time it takes a mosquito to go from an egg to an adult flying mosquito can go from 2 weeks to 5 days. Additionally, June is usually when we see the mosquito populations shift from floodwater mosquitoes to permanent water site mosquitoes. And it is this latter type of mosquito that can potentially transmit West Nile virus. We strongly encourage everyone to consider using a Centers for Disease Control (CDC) approved insect repellent. The CDC has a great website with information not only about the repellents but how to properly use them.
You can learn more at REPELLENTS, and they even have a search tool to help you find the best choice of repellent. Currently there are six active ingredients that the CDC believes to safe and effective when used as directed.
