There is no need to relocate during the adult mosquito treatment. Those who wish to minimize exposure for family members or pets may close windows and remain inside during the scheduled time period, which typically lasts three hours. Individuals who have chemical sensitivities may want to consult their physicians. All control treatments utilized are approved by the Federal and State Environmental Protection Agencies and are widely used by Vector Control agencies throughout California. 

Health Effects of West Nile Virus
Since the arrival of West Nile virus to California in 2003, 7,360 people across the State have contracted the disease; 339 of those cases were fatal. In 2020, there was one human WNV related fatality; 2015 was a record year for fatalities in the state with 55 deaths.

WNV infection does not cause symptoms in most people; however, for some individuals it can cause fever, headache, body aches and, in severe cases, significant neurological damage or death. Adults older than 50 years and individuals with certain chronic medical conditions such as diabetes, high blood pressure, cancer, and kidney disease are most at risk for serious complications.  

The public can play an important role in preventing the spread of West Nile virus. The following are some key prevention measures.

On your property:
•    DRAIN or DUMP standing water weekly. Mosquitoes lay eggs in stagnant water. 
•    Drain, remove or turn over anything that can hold water, such as flowerpots, planter bases, bird baths, toys, cans, rain gutters, pet dishes, buckets, and old tires. Fix leaky water faucets and sprinklers.
•    Screens on doors and windows should be tight-fitting and in good condition.
•    Do not let your swimming pool water fall below the pump circulation area. Free mosquitofish placement can be requested online at www.sccvector.org for placement in neglected pools or ornamental ponds.


Outdoor Activities:
•    Limit outdoor activities during DUSK and DAWN to prevent mosquito bites. Those are the times when the mosquitoes that transmit WNV are most active.  
•    If you need to go outside in an area where mosquitoes are active
          o    Dress in long sleeve shirts and long pants, preferably in light colors.
          o    Apply insect repellent approved by the Environmental Protection Agency, following label instructions.

For free assistance with mosquito control or other vectors, residents can contact the District office main line at (408) 918-4770 or fill out a service request online at www.sccvector.org.
