Stagnant water is the breeding ground for some of the most obnoxious summer pests including midge flies (also known as blind mosquitoes) and mosquitoes. Not only are these insects annoying, adult mosquitoes spread disease and midge fly swarms are a terrible nuisance that can trigger allergies and respiratory reactions.

Aquatic Midge Flies

These non-biting insects are found in and around lakes and ponds throughout Florida. Known by many common names including blind mosquito and fuzzy bill, they do not present health dangers to humans that mosquitoes do. They tend to emerge in swarms large enough to make outdoor activities impossible while staining everything in their way.

The goal is not to eliminate them, but to keep them in proper balance within the ecosystem. Midge fly populations grow exponentially in water high in nutrients and bottom muck, and low in oxygen; that don’t support fish. Shallow lakes or those with extended shallow areas around the shore tend to have more problems.

The female mosquito needs blood to produce eggs and a wet, protected place to lay eggs. Animals and algae provide everything they want, and for better or worse, lakes have an abundance of both. The natural way to limit mosquitoes is to make sure that your lake has natural predators including several species of fish, birds and dragonflies. A healthy balanced ecosystem will go a long way towards keeping these mosquito feeders around. As homeowners, you should try to eliminate any areas with standing water as well.

Widespread infestations are typically treated by your state or local government to prevent the spread of certain diseases, but for long term control a healthy lake, eliminating standing water is the best defense.

Long Term Solutions

For long term control of these pests, you must make the lake healthy. Aquatic Systems uses three distinct methods to control these pests during the stages when they live in the water, before they can cause trouble:

  • Larva treatments – Environmentally safe, cost-effective way to reduce midge fly and mosquito populations without affecting the food chain, fisheries or other non-target species.
  • Gambusia and Sunfish – Small native fish that feed on mosquito larvae. These fish are most effective in bright open waters devoid of aquatic weeds and algae where they can see and catch the larvae.
  • Aeration Systems – Eliminates areas of stagnant water, the preferred breeding ground of these pests. also improves overall water quality which keeps their predators in balance.
