Mosquito Fogging
To help protect public health and reduce the spread of diseases like Zika and West Nile virus, the City fogs for mosquitoes each year. Fogging occurs between 9:00 p.m. and 4:00 a.m. when mosquitoes are most active and pollinators like bees and butterflies are less active. This helps limit the impact on those critical species.
What You Need to Know:
Based on mosquito activity and community reports, fogging happens one to two weeks a year.
Weather or other delays may pause fogging, but crews will resume where they left off.
Residents with respiratory concerns should keep windows closed during overnight fogging.
Beekeepers should cover hives and limit bee access during fogging times.
If you or someone in your household has respiratory sensitivities or maintains beehives, you can sign up for mosquito fogging alerts through Notify Me on the City’s website.
Stay informed. Stay safe.
2025 City of Lancaster Mosquito 2nd Fogging Notice
The City of Lancaster will begin the 2nd mosquito fogging for 2025 on Sunday night, August 3rd, through Thursday night, August 7th (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 Fogging Map for section details.)
We aim to fog four sections per night, completing the entire City within that five-day window. We may continue to the next section if we get ahead of schedule.
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 while working 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 get in touch with 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.
The American Mosquito Control Association recommends remembering the three "Ds" of prevention and protection from mosquitoes:
DRAIN any standing water in barrels, tires, birdbaths, or other containers around your property.
DRESS in light colored, loose-fitted clothing. Most mosquitoes are attracted to dark colors, and most can bite through tight-fitted clothes.
DEFEND against mosquitoes by using an EPA-approved mosquito repellent like DEET,
Picaridin, or even a natural option like oil of lemon-eucalyptus.
If you follow these simple guidelines, you are helping to keep your communities healthy and safe.
For more information on mosquito prevention, visit the Fairfield County Health Department, the Ohio Department of Health, or the Centers for Disease Control (CDC).
