A Message from the Placer Mosquito and Vector Control District 

 

Larval mosquito treatment will begin on Thursday and will continue through Saturday.  Larval treatments involve an EPA-registered mosquito larvicide applied by a low-flying aircraft in an effort to prevent the emergence of adult mosquitoes and reduce the risk of mosquito-transmitted diseases. Treatments will occur during the daylight hours, most commonly in the early morning through the early afternoon.
 
Treatment area:
 
·        Western Placer County -  Treatment areas are all agricultural and will not include organic fields, with the larvicide material  applied directly to the fields.

 

 
Since several factors, including weather conditions, affect treatment activities, the District encourages Placer residents to check the District website for any changes to the treatment schedule and accompanying maps of the planned treatment areas. For an overview of our mosquito control programs, you may view the District video, also at www.placermosquito.org

Some important notes to consider:

 

• Most mosquito control strategies implemented by the District are designed to prevent mosquito eggs and larvae from developing into adult mosquitoes.  The District's preferred larviciding strategies are to use biological control methods, such as mosquito-eating fish, as well as biorational materials applied directly onto fields and pastures.
• The EPA considers biorational materials to have different modes of action than conventional or traditional materials, with greater selectivity and considerably lower risks to humans, wildlife and the environment.

A biorational larvicide is derived from a variety of biological sources, including bacteria, viruses, fungi and protozoa, as well as man-made equivalents of naturally occurring biochemicals such as pheromones and insect growth regulators. They are considered third-generation pesticides that are environmentally sound and closely resemble or are identical to chemicals produced by insects and plants.
