The Grand Forks Mosquito Control Program received overwhelming approval during a City of Grand Forks ballot measure on November 7, 1996. The citizens voted 91.8% to continue a mosquito control program implemented as a two year pilot test during 1995 and 1996. The program is designed to promote health and well being by reducing the risk of mosquito-borne diseases and reducing the nuisance level of mosquitoes in an environmentally sensitive manner.

The mosquito problem in Grand Forks is primarily generated by two types of mosquitoes, the floodwater (Aedes/Ocherotatus) and standing water (Culex) mosquitoes. The plan to control these insects is based on an understanding of their life cycle, reproductive cycle, habitat, and range of travel.  A comprehensive mosquito control program employs all phases of mosquito control, such as source reduction, surveillance, larviciding, adulticiding (ground spraying), and public education.

High Traffic Spray vs. Citywide Spray

When surveillance determines adulticiding (ground spraying) is needed, Mosquito Control crews will determine if they need a High Traffic Spray or a Citywide Spray.

A High Traffic Spray is where crews spray only areas in town that are high mosquito population areas. For example, parks, The Greenway, storm ponds, waterways, etc.

A Citywide Spray is where crews spray the entire city no matter if it's a high population area or not. Citywide sprays are announced via a news release from the City of Grand Forks.
