What types of spraying for mosquitoes take place during the year and where?
Most control efforts are directed at controlling mosquito larvae. Typically, breeding areas are treated with granular or floating “briquet” insecticides. Adult control (fogging) occurs later in the season, usually in July and August, in limited areas where surveys indicate that preventive measures have failed to keep the risk of West Nile virus and other mosquito borne illnesses below acceptable levels.
