The Metropolitan Mosquito Control District (MMCD) will be conducting surveillance and treatment activities in your community to reduce the risk of disease and annoyance in an environmentally-sensitive manner. Each year field staff at MMCD monitors and treats wetlands that breed mosquitoes with a fleet of trucks and helicopters.

Many of our seasonal staff begin working in April and residents of the seven county metro area may notice the green or white trucks with the MMCD logo or staff on bikes or on foot wearing brightly colored “Mosquito Control” shirts. At times MMCD employees may need to cross private property for access to check and treat areas for mosquito larvae.

If you have questions about mosquito control activities or concerns about an employee, please call the MMCD front desk at (651) 645-9149 or visit
