What is the Metropolitan Mosquito Control District?
MMCD is a local government agency that provides a range of services to Hennepin, Ramsey, Anoka, Washington, Dakota, Scott, and Carver counties, including residents in the Twin Cities metro. MMCD has been monitoring and controlling mosquitoes since 1958. They are funded by property taxes; in 2020, a property assessed at $250,000 will be charged about $12 for mosquito control.
What are the MMCD helicopters doing?
The helicopters apply dry pellets or granules to prevent larval mosquitoes from becoming biting adults. These are bio-rational control materials which specifically target mosquito larvae and pose no risk to human or animal health. MMCD helicopters DO NOT apply liquid control materials that target adult mosquitoes.

How does mosquito control work?
Did you know there are 51 species of mosquitoes in Minnesota, and 16 of those species bite humans? The two main controls used by MMCD for mosquito target the larval and adult stages of only the mosquitoes responsible for harassing and biting humans.
- Larvicides work by killing mosquito larvae before they can grow into biting adults. These materials are applied by hand to small mosquito breeding sites and by helicopter to areas larger than three acres.
- MMCD uses pyrethroids, which are similar to the natural botanical insecticides derived from chrysanthemums, to control adult mosquito populations. Adulticide applications are typically applied after research sampling determines a high concentration of mosquitos in high use areas such as parks and recreation areas, or in annoyance reports from residents. Areas scheduled for adult mosquito control are posted here at least 24 hours in advance of the actual treatment.

What else does MMCD do?
In addition to providing mosquito control and education for how to reduce mosquito-borne diseases, MMCD monitors deer tick populations and provides educational materials regarding Lyme disease and other tick-borne diseases, and conducts surveys for biting gnat populations and heartworm disease in dogs.
