Mosquito Spraying Scheduled for Thursday Night in Longmont
JULY 2, 2012 - Due to the increased number of mosquitoes found at Sandstone Ranch, Jim Hamm Nature Area, Union Reservoir and Left Hand Creek at Creekside, the City of Longmont's mosquito control contractor will spray these four areas with adulticide on Thursday, July 5 beginning around 9 pm, weather permitting.
The adulticide is applied by truck in ultra low volumes (.007 lbs/acre) with a water based chemical that is very effective against mosquitoes. This chemical is applied in the later evening hours when mosquitoes are most active. The designated threshold for spraying is triggered when any one of 11 trap sites throughout the City encounters adult mosquitoes of 100 or greater and 50% or greater of those trapped are of the Culex species or once WNV positive mosquitoes are found in any of the surveillance zones associated with Larimer, Weld or Boulder Counties and trap counts exceed 100 adult mosquitoes.
These trap sites are monitored and evaluated on a weekly basis by Colorado Mosquito Control. This information is shared between CMC, the Boulder County Public Health Department and the City. Typical hotspots for mosquito activity generally concentrate around water. These locations include Boulder County Fairgrounds, Jim Hamm Park, Sandstone Ranch, Union Reservoir and the St. Vrain Greenway.
The City of Longmont has contracted with Colorado Mosquito Control (CMC) 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, on occasion localized spot spraying is necessary. Localized spraying usually occurs around small ponds and streams where mosquitoes breed.
Rarely will the City conduct citywide spraying. Citywide spraying is not occurring on Thursday, only localized spraying at Sandstone, Jim Hamm,Unuion Reservoir and Left Hand Creek. Citywide spraying occurs only when there is a significant risk of West Nile virus and only after recommendations from Boulder County Public Health, the Colorado Department of Public Health and Environment, the CDC, and the Longmont City Manager.
The Boulder County Mosquito Control District spray schedule is published every Tuesday in the Boulder Daily Camera and Longmont Times-Call. The City of Longmont Spray Schedule normally appears every Tuesday in the Longmont Times-Call in conjunction with the Boulder County Mosquito Control Program.
July and August are typically the high point for mosquito season in Colorado and the threat of West Nile Virus mosquitoes is at its highest according to Dan Wolford, Longmont's Parks, Open Space and Greenways Manager. However, the mosquito season seems to have started early this year. Wolford reminds the public that the most effective means of combating the west nile virus is to remember the 4 Ds:
