A vector is any insect or arthropod, rodent or other animal of public health significance capable of harboring or transmitting the causative agents of human disease, or capable of causing human discomfort or injury.
The best way to prevent West Nile Virus infection is to avoid being bitten by mosquitoes.

Whenever You Are Outdoors
Avoid spending time outdoors at dawn or dusk, when
mosquitoes are most active.
Wear long pants and long-sleeved shirts.
Use DEET or Picaridin based mosquito repellent or Lemon Oil of Eucalyptus, according to label instructions.
Around The House
Eliminate any source of standing water in your yard.
Make sure window screens are in good repair and fit properly.
Report to the district any large breeding sites in your neighborhood:
Abandoned swimming pools. Click here to see a video
of mosquito larvae in an unused pool.
Accumulations of trash and containers capable of holding water.
In addition to eliminating mosquito-breeding sites around your home, you can help Vector Control in its battle against larger breeding areas by preventing excess water from running off your property.
Make sure sprinklers are positioned properly and in good repair.
Adjust sprinkler timers to prevent over watering. If water is
running off your lawn onto the sidewalk or curb, your lawn is
getting too much water. Over-irrigation is the primary source
of water in our gutters.
Check rain gutters for any leaves or debris that could be blocking
the flow of water. Click here to see a video of mosquito larvae
in a rain gutter.
Take your car to a carwash if possible. When washing your car at home, turn the hose off while you are soaping and washing, and divert the water to a vegetated area such as the lawn.
Sweep your driveway instead of hosing it down. Collect leaves and landscape debris and put them in your green waste cart. Just a few leaves in the gutter can cause water to back up and form a breeding site for mosquitoes.
If you notice standing water in the gutter between street sweeping days, please sweep it out to minimize mosquito-breeding areas.
