There are a few basic things you can do around your property to eliminate mosquito breeding grounds and reduce their population.
Eliminate standing water. This includes rain gutters, plant trays, old tires, buckets, toys, or any other places that standing water can gather.
Empty and change the water in bird baths, fountains, wading pools, rain barrels, and potted plant trays at least once a week to destroy potential mosquito habitats.
Areas on your property that frequently pool with water should be drained and filled with dirt
Keep swimming pool water treated and circulated.
