Gnat & Midge Control

Mosquitos, gnats, and midges can become a serious problem around lakes and ponds. These problems can include mosquito bites, general disturbance of peace and quiet outside, and the spread of disease. Additionally, in instances of mass hatching of gnats and midges, including the so-called “blind mosquito,” there can be a significant issue of soiling and staining. This occurs when millions of these organisms die and leave fecal material on surfaces like boats, docks, homes, and other structures. That’s why effective midge control is so important, as it helps mitigate these nuisances and maintain a cleaner, more enjoyable environment.

Origin

Unfortunately, the origin of most of these problems lies in your lake or pond. That’s because the life cycle of these pests includes an aquatic phase. During this phase, eggs hatch into larvae that inhabit the bottom of the water body and other underwater areas. Essentially, these serve as habitats before the larvae mature into adults. Lakes and ponds that have heavy amounts of weeds and algae provide an additional habitat for these pesky creatures. The same happens with the layer of muck and organic debris on the bottom of high-nutrient lakes and ponds. Fortunately, The Lake Doctors, Inc. can help with mosquito, gnat, and midge control in several different ways.

Mosquito Prevention
  • These insects thrive in stagnant water and do not do well when water movement is present. Therefore, adding an aerating fountain or aeration system can be very effective for significantly reducing the number of larvae. More specifically, this can be done using a bottom-diffuser (think aquarium air stone aeration). Small bottom-diffuser aeration systems include post-mounted air compressors, air hoses, and a bottom diffuser. These are very effective in water quality improvement and the control of insect larvae and reduction of bottom muck.
  • You can also use a variety of mosquito prevention products to control the insect larvae living in your lake or pond. One of the most effective and environmentally benign products utilizes a harmless bacteria known as Bacillus Thuringiensis.  When ingested by the mosquito larvae,  it makes them sick and die. This beneficial bacteria does not affect any other organisms than the ones targeted. You can schedule periodic applications during the mosquito season to help dramatically reduce the numbers of larvae.
Natural Midge Control Options
  • Another sustainable, inexpensive, and environmentally sensitive means of helping to control mosquito, gnat, and midge larvae is the stocking of a small minnow. These fish look much like a guppy called gambusia, otherwise known as mosquitofish. These are typically stocked in the hundreds or the thousands and function to eat inspect larvae, one of their favorite foods. In turn, the gambusia reproduce and become an important part of the food chain, helping to sustain the growth of gamefish like bass.
  • Other fish can also be effective in controlling mosquito larvae, such as bluegill and catfish. We also stocks these types of fish, but our stocking of these fish is more seasonal as they are typically stocked in the spring as small fingerlings.
