Aerial Adulticide

(Back to the Department List.)

During periods of high adult mosquito activity, it is necessary to treat large areas of the County; this can be accomplished by using helicopters or fixed-wing aircraft. Lee County Mosquito Control District has five Douglas C-47’s allowing for quick coverage of the county when there is a significant mosquito problem. Equipped with the latest technologies of GPS (Global Positioning System) navigation and night vision goggles these fixed-wing adulticiding missions are conducted at night, usually between 10 p.m. and 2 a.m., when adult mosquitoes are active and more likely to be exposed to the very small droplets produced by the ULV (Ultra-Low-Volume) spray system. Lee County also has one Huey equipped with a high pressure ULV spray system for treating the outer islands of the County, these missions are conducted in the early morning hours, usually at sunrise.

In Map-Info we create a map of the area to be treated and add any flight obstacles. The mission is then saved to a disk. After the mission is completed the spray data is saved. It is then downloaded to the computer where treatment overlays the flight path on the map.
