Neglected Swimming Pools / Backyard Mosquito Sources

The steep decline in property values, increasing foreclosures, and abandonments throughout Washoe County has resulted in an increase in the number of "backyard" mosquito sources. Abandoned and unmaintained water features such as swimming pools, hot tubs, ponds, bird baths, and fountains are capable of producing mosquitoes. 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.

Pond aerators like the one pictured improve water quality and suppress mosquitoes and their laying of eggs.

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 mosquitoes from colonizing an unmaintained water feature. Floating covers or tarps with gaps are not effective.

This permeable cover completely blocks the surface of the pool and prevents mosquitoes from colonizing there.
