Check out the District's Midge Study here.

Midges are an important factor in the food chain for local and migratory ducks, geese, and other large aquatic birds. They are not a disease threat to pets or people; however, in large numbers, midges can impact local industries, agriculture, and can be a significant nuisance. Midges look similar to mosquitoes, but most do not bite.

  • They are an essential food source for fish and other aquatic insects
  • Chironomids are important organisms in aquatic habitats
  • Its larvae "clean" the aquatic environment by consuming and recycling organic debris


  • Find and eliminate the sources of midge larvae
  • Look for habitats where they develop, such as: lakes, water reservoirs, open water where vegetation is attached, and during the summertime, where water frontage is close to buildings and homes.
  • Use ditches to drain away areas of standing water and try to eliminate unnecessary lighting during the evening
