Mosquito Control

The City of Centennial contracts with Vector Disease Control International to provide an Integrated Mosquito Management Program that helps protect public health by reducing the risk of West Nile virus (WNV) and controlling nuisance mosquito populations.

The program includes monitoring and targeted treatment efforts to minimize mosquito activity throughout the community. Residents can learn more about West Nile virus prevention and mosquito control by visiting Arapahoe County Public Health.

Remember the 4 D’s

Defend

  • Consistently wear and reapply EPA-registered repellent when outdoors.
  • Always follow label guidelines to ensure safe and effective use.
  • Be sure to keep pets and livestock up to date on vaccinations and heartworm preventatives.

Dress

  • Mosquitos are most attracted to dark clothing.
  • Wear closed-toe shoes, light colors and loose-fitting long sleeves and pants to keep your skin protected.

Drain

  • Mosquitos require standing water to reproduce. Regularly empty and drain objects that collect rainwater to eliminate breeding areas.

Dusk and Dawn

  • Limit spending time outdoors when mosquitoes are most active.
  • During the day, mosquitoes typically linger in cool, shaded places like thick weeds, ivy, bushes and wood piles.

Mitigation

Throughout the summer, 44 active larval inspection sites are monitored weekly by Vector Disease Control International. If mosquito larvae/pupae are detected, they are eliminated via the application of bio-larvicides, primarily a soil bacteria-based product called Vectobac G. These larvicides are extremely target-specific with no non-target effects.

Currently, there are four surveillance trap sites in Centennial where CDC Light Traps are set/collected weekly throughout the summer. The purpose of these traps is to determine which species of adult mosquitoes were caught by the trap and in what numbers. Surveillance trap reports are issued weekly.
