Managers Update, Spring 2012

Spring weather signals the start of insect activity in the Sacramento Valley. District employees look forward to addressing vector management issues within our District. Urban water management is critical, with water use followed by warm temperatures potentially making a prime habitat for developing mosquitoes. Make sure you empty water containers such as pet dishes or flower pots at least once a week to avoid developing mosquitoes in your own yard. Running the filters on pools and spas will prevent these water sources from producing mosquitoes.

We have already seen evidence of West Nile virus in Sacramento County this year, with several birds testing positive for the virus. If you see a bird, particularly a crow or magpie lacking obvious signs of trauma that has been dead for less than 24 hours, please call 1-877-968-2473. Crows and magpies are particularly susceptible to the disease, so they make excellent early warning sentinels for virus activity in your area.

Remember to wear a good repellent when staying outdoors during the times when mosquitoes are most active (Generally during the early morning and late evening hours!) ALWAYS read the label and follow the directions of the product you are using.

Management of mosquito development sites include the principles of integrated pest management. Physical control (proper drainage), and cultural control (turn the water off before it stands for more than three days!) are all techniques that can be used by local residents to reduce mosquito populations. District staff is trained to perform biological control (the proper stocking of larvivorous fish) and chemical control (the use of EPA-registered pesticides) to further manage mosquito populations. Together, the district and the community can ensure a safe, healthy environment for all.

Presentations on mosquito and West Nile virus prevention are also available for your school, community or neighborhood group. Our website makes it easy to request a presentation or any of our other services which include reporting a neglected pool,  free mosquitofish for your pool or pond and a home service inspection. You may also stay updated on District activities and interesting information by becoming a friend on Facebook or following us on Twitter.
