Biological mosquito control is the use of other living organisms to control mosquito populations.  While mosquitoes have many natural predators, in general, biological controls strive to achieve a balance between the predator and prey and this balance tends to favor the prey.  Simply put, mosquitoes can usually reproduce faster and in greater numbers than the biological controls, thus ensuring that there will be sufficient prey for the predator.  Despite this, biological controls are an important tool in controlling mosquitoes and can be employed to great effect in certain situations.
 

The primary biological control we use is the mosquitofish, Gambusia affinis. The mosquitofish preys on mosquito larvae allowing us to keep mosquito populations under control.  When introduced into a mosquito breeding source, the mosquitofish quickly adapts, multiplies and controls mosquitoes in a given area.
