Managers Update for July, 2010

Managers Update

The weather is hot and mosquitoes are out! West Nile Virus (WNV) activity has started in our area and we’ve seen positive birds and mosquito samples. Such activity is a clear indication that the virus is active and that anyone can become infected. All it takes is one bite from an infected mosquito to get the disease. We urge residents to be aware and take proactive measures to protect themselves. Draining all sources of standing water around the home is critical! We remind you to please ONLY irrigate your lawns, and not the sidewalks and gutters. Water going into storm drains and basins produce mosquitoes and affect everyone in the neighborhood.

Summer is a time for BBQ’s, camping, evening walks and spending more time outside, especially in the early morning and evening hours when mosquitoes are most active. We encourage you to dress appropriately and protect yourself by wearing an effective mosquito repellent to ensure you are not bitten. The CDC encourages the use of repellents containing the active ingredients DEET, Picaridin, IR3535 and the plant based Oil of Lemon Eucalyptus. As part of our Public Information and Education Campaign, the District offers free repellent to sports leagues, park and recreation departments, and community organizations for any outdoor evening events. If you would like repellent please contact our office by emailing us at For more information on the use of repellent visit the CDC’s Repellent website.

Home foreclosures and neglected swimming pools continue to be a problem. While we receive daily reports of neglected swimming pools, public cooperation is still needed to ensure we treat as many pools as possible to keep residents safe. Just one neglected swimming pool can produce thousands of mosquitoes and infect an entire neighborhood! If you know of a neighbor that cannot keep their pool clean, please give us a call. District staff will add mosquitofish to the pool which will keep mosquitoes under control until the pool can be properly maintained. Please note that even with mosquitofish in the pool, the water will continue to be green and dirty until the pool is properly filtered and chemically treated. In the meantime, we urge residents NOT to add chlorine to the pool because this kills the fish and starts the mosquito production cycle again.

As summer gets underway, our commitment to help protect public health by controlling mosquitoes is our top priority. We will continue to treat mosquito sources in both urban and rural areas, our advertising campaign to educate the public will intensify, and our community outreach will be strong. Please contact us if you would like a presentation for your community group or classroom or by filling out a presentation request form online.

Together, we can ensure a safe and healthy environment for all. If you need assistance with mosquitoes please call us at 1-800-429-1022 or submit an online service request.

We are here to serve you!
