West Nile Ground Spraying FAQs
Why would the City consider ground spraying? The goal of spraying in general is to limit the possibility of spreading the West Nile virus from birds to people with the end result being that no-one dies or becomes seriously ill from the virus. Spraying is done as the final stage in an integrated program of mosquito management to prevent human illness and death.
What chemical is being used to spray the affected areas?
Aqua-Reslin is being used in our ground spraying applications. This chemical is approved by the Environmental Protection Agency. The label for Aqua-Reslin is available here and the material safety data sheet is available here.
What is the rate of dispersion?
Application rates are listed on the insecticide label as approved by US EPA. Applications of Permanone occur at a rate of .0030 pounds of active ingredients per acre. The contractor is using a variable flow sprayer that automatically adjusts the sprayer flow rate as the vehicle travels, based on the speed as determined by GPS. The sprayer can spray at vehicle speeds between 3 and 22 miles per hour. The sprayers will not spray at speeds higher than 22 miles per hour
Is spraying supervised?
Yes, spraying is supervised. Drivers are instructed to obey all posted speed limits.
What if the spray truck encounters a pedestrian? Drivers do not normally stop the vehicle if they encounter a pedestrian. They are instructed to immediately turn off the spray and drive past the pedestrian with the spray off.

- Avoid being outside during spraying; close windows and keep pets inside.
- If skin or clothes are exposed, wash them with soap and water.
- Rinse homegrown fruits and vegetables with water as a general precautionary measure.
- Cover small ornamental fish ponds.
