If you are spending time outdoors when mosquitoes are active (especially at dawn and dusk), apply insect repellent according to label directions.

Make sure that doors and windows have tight fitting screens. Repair or replace screens that have tears or holes.

Eliminate all sources of standing water on your property that can support mosquito-breeding. Backyard sources that collect rain or sprinkler water can produce substantial numbers of mosquitoes. Examples of such sources include: used tires, buckets, swimming pools, boat and pool covers, barrels, wheel barrows, livestock watering troughs and almost any container that will hold water.

Report non-maintained (green) swimming pools to the District. The District inspects and treats hundreds of pools every year. One neglected pool can produce thousands of mosquitoes which can affect an entire neighborhood.
