The City of Longmont Mosquito Management Program can provide services to residents regarding:

  • Information about mosquito biology and source reduction of mosquito habitats
  • Information on pro gram components, operations, and monitoring efforts within the city
  • Seasonal West Nile Virus activity
  • Personal protection options for mosquito annoyances and West Nile Virus risk
  • Respond to reports and concerns of mosquitoes and possible larval mosquito habitats
  • Perform larvicide applications to control mosquito larvae at no cost to the property owner
  • Stock residential ponds with fat head minnows for biological control

Please call 970-962-2583 or 970-663-5697 to report any water that stands for more than 4 days, mosquito annoyance concerns, or for information regarding West Nile Virus prevention. Resident phone calls continue to locate new mosquito habitats, thereby reducing the number of mosquitoes in the backyards of the residents of Longmont.

Background
In 2002, City Council voted in favor of establishing a formal mosquito control program in the City of Longmont. The purpose of the program is to protect residents from disease and annoyance through a comprehensive Integrated Pest Management approach. The 2014 larval control service area for the City of Longmont included approximately 28 square miles of private and public lands in the city limits of Longmont. Beginning in 2009, and each year since, the City of Longmont and Boulder County Public Health agreed to cost share larval control efforts in a portion of unincorporated Weld County which encompasses Union Reservoir and Sandstone Ranch Community Park. The Weld County Service Area covers 9 square miles of unincorporated lands, east of County Line Road and south of Ute Hwy. Both entities recognize that this area presents a significant number of larval mosquito habitats, which can produce mosquitoes that will migrate into Longmont city limits and Boulder County. To date, 409 larval mosquito habitats are included in the regular inspection and larviciding program for the City of Longmont Mosquito Management Program. There were 5 new larval sites added to the routine inspection program in 2013.

Program Goals
The primary objectives of the City of Longmont Mosquito Control Program is to suppress the development of larval mosquitoes in wetland and other sites, conduct surveillance of adult mosquito populations and provide limited adult mosquito control when predetermined disease and annoyance thresholds have been surpassed. These objectives are reached using a framework of Integrated Pest Management whose goal is to provide the greatest level of control of pest and disease vector mosquito populations while maintaining a balanced use of cultural, biological, and least-toxic chemical procedures that are environmentally compatible and economically feasible.

Larval Control Efforts in the City of Longmont
This environmentally focused program always uses biological control choices first to reduce mosquito populations at the source…the aquatic larval habitats. Larvicide applications are designed to reduce mosquito populations below established disease thresholds. 

Field technicians methodically inspect larval habitats twice a week, weekly, bi-weekly or post rainfall, as deemed necessary based off of historical data.  A technician may spend the day inspecting a variety of habitats ranging from urban mosquito breeding locations (storm drains, catch basins, wading pools, paddle boats & tire piles), as well as cattail marshes, stagnant ditches, reservoir edges and irrigated pastures.  Inspections are performed to determine whether larval mosquitoes are present or not at a site. Once the presence of mosquito larvae is confirmed, larvicides are applied.

CMC’s favored method of larval mosquito control is through bacterial bio-rational products.  The main product used by CMC is a variety of naturally occurring soil bacteria, Bacillus thuringiensis var. israeliensis.  Bti, as it is known, has become the cornerstone of mosquito control programs throughout the world.  The benefits include its efficacy and lack of environmental impacts.  When used properly successful control without impact to aquatic invertebrates, birds, mammals, fish, amphibians, reptiles, or humans can be achieved.  A broad label allows for the use of this product in the majority of the habitats throughout the service area. Residents who wish to control mosquito larvae in their own residential backyard ponds can purchase Bti, known as Mosquito Dunks, at commercial retailers such as Home Depot, Ace Hardware and Lowe`s.

NEW in 2014! City council approved an enhanced larval control inspection program. Sites which are known to historically produce mosquito larvae are inspected every 5 days to reduce the number of mosquitoes that can possibly emerge as biting adults and become infected with West Nile virus.

City council also approved funding for the addition of 4 new mosquito surveillance locations in 2014. This addition brings the totl number of mosquito traps to 16. The addition of traps will improve the quality of data being collected across the City and aid in the decisions regarding the need for mosquito spraying (adulticiding). Mosquito traps will be set on Sunday evenings in the City of Longmont, weather permitting. Traps will be collected and mosquito idenitfication will take place on Mondays.
