Mosquito Larvae

Mosquito larvae live in water until they pupate and develop into adult mosquitoes. While the larvae of most species use siphon tubes for respiration, Anopheles larvae do not have a siphon and must stay parallel to the water's surface in order to breathe. Coquillettidia and Mansonia larvae cling to plants to access air supplies. Mosquito larvae consume microorganisms and organic matter in water.

Mosquito larvae may be as large as 1/4-inch and can be clearly visible in water. Larger larvae are located closer to the water's surface. Mosquito larvae are extremely sensitive and will submerge for protection if they sense disturbance.

Mosquito control involves the elimination of existing infestations and the prevention of re-infestation through the eradication of larval populations. In order to control mosquito larvae, regular inspections of possible breeding sites must be conducted.

Because mosquito larvae cannot survive away from water, areas affected by an infestation should be combed for water sources. Water that has been stagnant for three days is a prime habitat for mosquitoes. Some species require minimal amounts of water to thrive; even water sources such as birdbaths are potential breeding sites. Chemical or bacterial larvicide treatment may be necessary in areas where larvae are found.
