The Town of Concord contracts with East Middlesex Mosquito Control Project (EEMCP) for the following services:
- Adult mosquito surveillance
- Larval mosquito control with Vectolex WSP (biological agent) at 2,400 catch basins
- Ground applications of Bti (biological agent) at wetlands to control potential mosquito larvae
Based on mosquito surveillance and presence of animal and/or human cases of WNV and EEE, the Massachusetts Department of Public Health updates its current Risk Level for WNV and EEE in Concord and other towns at least weekly during the summer mosquito season. Please see MPDH's webpage on Mosquito-Borne Diseases for more information.
Eastern Equine Encephalitis (EEE) is a rare but serious disease caused by a virus, which is spread by infected mosquitoes. The EEE virus can cause inflammation or swelling of the brain (encephalitis). We encourage you to read the FAQ’s to learn a little more about EEE and Concord’s response in 2019 when human and veterinary cases were found in our area.
