2025 City of Lancaster Mosquito Fogging Notice
The City of Lancaster will begin mosquito fogging on Sunday night, June 22nd, through Thursday night, June 26th (ending Friday at 4:00 a.m.), weather permitting.
Fogging will take place nightly from approximately 9:00 p.m. to 4:00 a.m.
We will start on the west side of town in Section 15 and move east, ending in Section 1. (Please refer to the Lancaster Mosquito Spraying Map for section details.)
Our goal is to fog four sections per night, completing the entire City within that five-day window. If we get ahead of schedule, we may continue to the next section.
Please note: Inclement weather or high winds may delay fogging. Any postponed sections will be rescheduled for the following night.
We understand that schedule changes may be inconvenient, but we appreciate your patience as we work around weather conditions.
For your safety, residents and pets should remain indoors with windows closed between 9:00 p.m. and 4:00 a.m.
If you have beehives or pollinator gardens, please contact us in advance. We will do our best to turn the fogger off when passing your property.
Thank you for your continued cooperation in helping to control the mosquito population.
