West Nile Detected: Longmont to Begin Spraying for Mosquitos

Larimer County has recorded the first positive West Nile Virus mosquito pool of the season. While Boulder County has not yet recorded a positive pool the positive detection in neighboring Larimer County is an indication that WNV is present in Boulder County and makes it safe to assume that mosquitoes from any area are potentially positive.

 

The City of Longmont contracts with Vector Disease Control International (VDCI) to spray local neighborhoods in Longmont to control the spread of West Nile Virus. Spraying is triggered – per predetermined spray area – when traps in that area exceed 150 mosquitoes per trap AND when West Nile Virus positive mosquitoes are discovered in Larimer, Boulder or Weld Counties. The following standard spray areas have met the threshold and will be sprayed beginning at sunset this Thursday, June 27, 2024 and continuing through the evening or early morning, weather permitting.

  • Jim Hamm Nature Area (LM-03)
  • Sandstone Ranch (LM-22)
  • St. Vrain Greenway @ Emery (LM-28)
  • Renaissance (LM-34)
  • Rough & Ready South (LM-43)
  • Great Western Cattail Court (LM-44)

 

Boundaries of the predetermined spray areas can be seen on a map provided by the City and VDCI on the West Nile Virus webpage. When the triggering events occur, notice is provided on this webpage on Tuesdays that spraying will occur later that week – typically on Thursday evenings – giving residents 48 hours’ notice of any spraying.
