When the City does spray, what area(s) will be sprayed and at what times?

Spraying will be implemented based on the Integrated Pest Management criteria:

  • Time of year
  • Current level of mosquito activity
  • Weather
  • Surveillance results

One positive mosquito or human case will initiate control measures appropriate to the applicable conditions in an attempt to stop or slow transmission.


Frisco will spray between 1/2 mile to 1 mile radius of the affected area, depending on population density. Frisco will spray areas two days consecutively. The application truck will drive streets of areas noted from 10 p.m. to 5 a.m.


If you have questions, please contact Health & Food Safety.
