Physical control, also known as source reduction or habitat modification, is another form of control utilized in the District’s IPM plan. Physical control is usually the most effective of the mosquito control techniques available and is accomplished by eliminating, or significantly reducing, mosquito breeding sites. The primary operational objective of physical control is to reduce the mosquito carrying capacity of a source to preclude the use of control methods that would adversely impact the environment and wildlife. This can be as simple as properly discarding old containers which hold water or as complex as developing a regional drain system for storm water. Physical control is important in that its use can virtually eliminate the need for pesticide use in and adjacent to the affected habitat.
There are many types of mosquito breeding sources in San Joaquin County capable of being reduced by physical control techniques. Generally, only man-made or managed mosquito sources are considered for physical control. Following is a representative listing of mosquito breeding sources and recommendations for physical control:
