Managers Update, Fall 2010

Fall is here and temperatures have dropped significantly, this should slow down mosquito activity for the remainder of 2010. This time of year tends to bring cooler days which suppress the populations of the major West Nile virus vectors. Overall our area and the entire state have experienced a milder season for West Nile virus than past years. Potentially this could be attributed to a cooler than usual summer and better mosquito control tactics. However, it’s important to note that while we haven’t seen the same amount of human cases, infected birds and mosquito samples as other years, this does not decrease the severity of the disease and the public should still take necessary precautions to prevent mosquito bites and West Nile virus.

Though we are having cooler weather, it is possible for warm temperatures to return and it is important that you continue to perform sound mosquito management techniques such as draining all standing water around your home and wearing an effective mosquito repellent, especially during early morning and evening walks or if you are practicing any outside sports. We urge you to apply repellent if you are outside during dawn and dusk, which are the peak times for mosquito activity. The District has free repellent available to the public and willingly gives it out to interested sports groups, community organizations or neighborhood associations hosting evening events. Please contact us at 800-429-1022 or email if you are interested in obtaining free repellent wipes.

Our Public Information and Education Department is currently distributing 2011 Fight the Bite calendars that feature the winning entries of our spring 2010 Fight the Bite calendar contest. If you would like a free calendar please give us a call. Presentations on mosquito and West Nile virus prevention are also available for your school, community or neighborhood group. Please use our online forms to request free mosquitofish for your pool or pond or a home service inspection.
