Mosquito Control Program

Mosquito Control Program

The Town of Johnstown has implemented biorational integrated mosquito management (IMM) through Vector Disease Control International (VDCI) for many years. The primary objective of this program is to monitor and reduce mosquito populations through the use of specific, environmentally sound, control techniques in order to protect residents from the threat of mosquito-borne diseases. 

Open communication is maintained by VDCI between the Town of Johnstown, County Departments of Health & Environment, the Colorado Department of Public Health & Environment and surrounding municipalities in order to ensure that the highest level of mosquito control and epizootic response is achieved. This diligent and cooperative communication is important to the Town of Johnstown’s mosquito management program and provides significant benefit to public health throughout the entire area.
