OPERATING SCHEDULE

The 2025 spray season has an anticipated start date of July 7 and will run until conditions no longer support fogging, or until funding is exhausted.

Mosquito fogging schedule:

Monday - Thursday nights beginning at 9:30pm

when all conditions are met: 

1 - Temperatures above 50F

2 - Not raining

3 - Winds below 10mph

4 - mosquito trap counts indicate a need

This year's delay was due to the old fogger becoming unserviceable and waiting for the new fogger to arrive and be calibrated.
