Mosquito control 

In the interest of safety to our residents, the Town of Severance conducts ongoing Integrated Mosquito Management. The goal of this program is to monitor and reduce mosquito populations through the use of environmentally sound control techniques in order to protect residents from the threat of mosquito-borne diseases.

Vector Disease Control is the provider of these services.  VDC and the town communicate with the Weld County Department of Health & Environment, the Colorado Department of Public Health & Environment, and surrounding municipalities in order to ensure that the highest level of mosquito control is achieved. This diligent and cooperative communication is important to the Town of Severance’s mosquito management program and provides significant benefit to public health throughout the entire area.

Traps are used to monitor the assorted types of mosquito population and, based on the weekly trap findings, VDC conducts mosquito spraying (fogging) throughout the community when weather conditions are conducive to the best effectiveness.  Questions about the program can be directed to Broox Boze with Vector Disease Control at  970-278-9977.

June 2019 Mosquito Summary


Scheduled Spraying/Applications

As always, communication with our residents is very important to us.  In the process of getting the first application of the mosquito season done, we were unable to get notification out before the application happened.  To ensure that you are aware going forward, the application schedule for the summer can be found below.  We will also send email and text notifications to those who have subscribed to “Alerts” on the Subscribe Page of the website.  Application operations will take place between dusk and dawn and, as always, are weather dependent.  An interactive map with the Severance application areas and info regarding the last application can be found HERE.

2019 Schedule for Mosquito Control: 6/26, 7/10, 7/17, 7/24, 7/31, 8/7, 8/14



During Fogging Operations:
Remain indoors when fogging takes place in your neighborhood.

People who suffer from chemical sensitivities or feel fogging could aggravate a preexisting health condition should consult their doctor or local health department and take special measures to avoid exposure.

Close windows and doors and turn off your air conditioning (or set it to circulate indoor air) when fogging is taking place in the immediate area.

Do not let children play near or behind truck-mounted applicators when they are in use. Keep children inside during fogging and for about one hour after fogging truck(s) leave the area.

Bring pets inside and cover ornamental fish ponds to avoid direct exposure.  Consult your doctor if you think you are experiencing health effects from the fogging.

More information about pesticides can be found HERE on the EPA’s Web site.

To protect yourself from mosquito bites, the Town of Severance recommends the following precautions:

  • Choose a mosquito repellent that has been proven to be effective against West Nile Virus-carrying mosquitoes. Ones that contain DEET, Picaridin, Oil of Lemon Eucalyptus (with active ingredient PMD, or p-menthane diol) or IR3535 are known to be effective.
  • Keep exposed skin covered or use a repellent when out at prime Culex mosquito-biting hours; between dusk and dawn.
  • Drain standing water in your yard or in your garden.
  • Add mosquito-eating minnows to or a mosquito “dunk” to ornamental ponds that feature still water.
  • Keep window screens repaired.

Please visit Vector Disease Control for information regarding the pesticides used during these spraying/fogging operations.
