Fleming schedules first mosquito fogging of the summer Tuesday evening

The Town of Fleming sent its first mosquito fogging crew out Tuesday evening, with spraying planned from 7 p.m. to 9 p.m. across all areas of town. The seasonal work is part of Fleming’s summer routine, and the town says it fogs on Tuesday nights whenever weather and wind allow.

If Tuesday conditions do not cooperate, Fleming shifts the work to Thursday night instead. The town’s Health & Safety page says residents can sign up for text or phone-call reminders, giving people a way to know when the maintenance crew will be out and plan around the spray.

Fleming says its Town Maintenance Assistant Manager handles the work around town using Fyfanon, a liquid malathion. The town’s live feed says that schedule has been followed for 30 years, underscoring that the fogging program is a long-running local practice rather than a one-time response.

The timing matters in a place like Fleming, where summer evenings bring more activity to sidewalks, yards, parks and community spaces. The town’s approach is aimed at nuisance mosquitoes as warm-weather use of those spaces increases, and the fogging pattern gives residents advance notice before crews move through town.

The program also fits a broader public-health backdrop in Colorado. The Colorado Department of Public Health and Environment says West Nile virus season typically runs from late spring through early fall, with the highest risk of transmission from July through September. The state agency says mosquito-borne infection can show up as early as May and as late as December, and that mosquitoes can transmit West Nile whenever they are active.

That risk has made mosquito control a recurring issue for towns across the state, including small communities in Logan County that rely on local maintenance schedules and weather-sensitive work. The county’s own emergency-management infrastructure and weather monitoring matter here because Fleming’s fogging depends on conditions that can change quickly from one evening to the next.

Fleming’s summer schedule is now in motion, with the town saying Tuesday nights remain the standard and Thursday serving as the backup when the weather gets in the way.
