NEWS RELEASE
CITY OF LONGMONT
*************************
The City of Longmont will again spray local neighborhoods to control the spread of West Nile Virus this week following the identification of three positive mosquito pools in Longmont and Boulder County.

In keeping with Longmont’s West Nile Virus control plan, the City’s mosquito control contractor, Vector Disease Control International (VDCI), will spray to eradicate mosquitoes for the second time this season on Thursday night, July 29, 2021, weather permitting. Should thunderstorms and/or wind interfere with the spraying process, spraying will be scheduled for Friday night, July 30.

Eleven of 12 zones in the City of Longmont will be sprayed this week:

Jim Hamm (LM-03)
Garden Acres park  (LM-10)
Sandstone Ranch  (LM-22)
Union Reservoir  (LM-23)
Great Western/Mill Village (LM-27)
St Vrain Greenway (LM-28)
Creekside  (LM-31)
Renaissance  (LM-34)
Lanyon Park/Stoney Ridge  (LM-41)
Izaak Walton Park (LM-42)
Rough & Ready South  (LM-43)

Longmont fogging is triggered when West Nile Virus positive mosquitoes are discovered in Larimer, Boulder or Weld Counties and when Longmont traps exceed 150 mosquitoes per trap. Boundaries of the predetermined spray areas can be seen on a map provided by the City and VDCI on the West Nile Virus webpage at LongmontColorado.gov/westnile.

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.

Boulder County Public Health and Longmont officials urge residents to take necessary precautions to protect themselves. Keep safe this summer, and remember the 4 Ds:

  1. Use Deet or an alternative repellant
  2. Dress in long sleeves and pants
  3. Avoid outdoor activities from Dusk until Dawn
  4. Drain standing water, i.e. birdbaths, outdoor planters, tires stored outside, etc.

The City of Longmont has contracted with VDCI to implement an "integrated pest management program" to combat mosquitoes that might carry the West Nile Virus. This program focuses on first attacking mosquitoes in their larval stage before they become airborne. This is the best method since it eliminates mosquitoes before they hatch. This method also minimizes fogging to kill the adult, airborne bugs. However, some localized spraying becomes necessary when the West Nile mosquito population increases due to habitat and weather conditions.

VDCI uses state-of-the-art technology, calibrated application timing, and least-toxic products to minimize non-target impacts. All adult mosquito control is accomplished using Ultra Low Volume (ULV) fogging equipment and is performed after dusk when the majority of mosquito species are most active.

VDCI maintains a database of Longmont residents who have provided requests to be notified of spraying and/or requests to not have their address included in the spraying operations.  Residents have three options for requests made to VDCI:

  1. Call Notification Only - VDCI will phone you before spraying in your neighborhood.
  2. Address Shutoff Only - VDCI will shut off the spray machine while driving past your property.
  3. Notification & Shutoff - VDCI will phone you before spraying in your neighborhood and shut off the spray machine while driving past your property.

Those interested may contact VDCI to make a notification or shutoff request online or by calling 303-466-1892 or 877-276-4306.

Residents can also sign up for eNotifications to receive weekly updates once WNV-positive mosquitoes have been identified in the tri-county area. Be sure to select the West Nile Virus category.
