Miami-Dade County has a sub-tropical environment and is home to approximately 45 species of mosquitoes.  The Mosquito Control Division was created in 1935 to serve the residents of Miami-Dade County.

Their goal is to control the mosquito population using the most effective methods, techniques, equipment, and insecticides, thus enhancing the quality of life for all residents, reducing the possibility of mosquito transmitted disease.

County residents are encouraged to contact the Mosquito Control Division if they are experiencing mosquito nuisance. Resident's complaints are serviced either by truck spraying, aerial spraying, or by site inspections, dependent upon the location and the season of the year.

The main number for the Mosquito Control Division is (305) 592-1186. Office hours are Monday-Friday, 8:00 am - 4:30 pm. The resident calling is requested to give their name, address, telephone number, zip code, and nature of the mosquito problem. Responses to complaint calls are usually serviced within 24 - 48 hours.

Although there are 40+ mosquito species found in Miami-Dade County, only a few create sufficient problems that require control measures. The Salt Marsh mosquito, the Pasture Mosquito, the Domestic Mosquito, the Tiger Mosquito and the House Mosquito are commonly found, and create annoyance by their bite. In addition to their annoyance, mosquitoes can also transmit diseases such as Dengue Fever, Encephalitis, Malaria, and dog heartworm.
