Backyard Mosquito Sources
Abandoned and unmaintained water features such as swimming pools, hot tubs, ponds, bird baths, and fountains are capable of producing mosquitos. Any structure that holds water is a potential mosquito habitat.
Small standing water sources around the home should be drained or cleaned regularly. Larger sources such as swimming pools, hot tubs, horse troughs and ornamental ponds require regular maintenance to prevent mosquito habitat development.
Swimming pools need a working filtration system to prevent mosquito habitat development. Components of a working filtration system include: filter, pump, chlorinator, return inlets, skimmer and main drain. Pools should be covered whenever possible. Only covers that completely block the water's surface will prevent mosquitos from colonizing an unmaintained water feature. Floating covers or tarps with gaps are not effective.
To report neglected water features or any other mosquito activity please contact the Vector-Borne Disease Prevention Program.
