Mosquitoes - Resources

The San Gabriel Valley Mosquito & Vector Control District (SGVMVCD) routinely surveys for mosquito-borne diseases such as West Nile and St. Louis encephalitis and Western equine encephalomyelitis. Adult mosquitoes are routinely trapped and tested for these viruses. Sentinel chicken flocks are strategically placed throughout the Valley and are tested every 10 days for infection. Wild bird surveillance provides an opportunity to test important reservoir hosts for infection with WNV.
Our Technicians survey the San Gabriel Valley Mosquito & Vector Control District every weekday for sites where mosquitoes may breed and eliminate or controls these as necessary. The San Gabriel Valley Mosquito & Vector Control District provides free home and yard inspections for mosquito sources and provides mosquito fish to interested residents for placement in ponds, water gardens, and watering troughs. 

The San Gabriel Valley Mosquito & Vector Control District works to educate the public by participating in local community events and hosting lecture programs for local schools, civic organizations, and homeowners and neighborhood associations.

Please contact the San Gabriel Valley Mosquito & Vector Control District if you or your association would like to request a speaker for an event or a tour of the District, free of charge.

What Should You Do
  1. Immediately report black-and-white, day-biting mosquitoes. Even one bite is too many.
  2. Got junk in your yard? Clean it up! These mosquitoes are ‘container breeders’ and will lay their eggs in toys, soda cans, and even trash around the yard. Check your yard carefully for anything that will collect rain or sprinkler water.
  3. Do not grow plants in water-filled buckets or vases - even indoors. Remove saucers from under potted plants. These can breed hundreds of mosquitoes every week.
  4. If you store water, make sure all containers are tightly covered to keep mosquitoes out.
  5. Take the extra step: Scrub outdoor containers that have held water with hot, soapy water to kill mosquito eggs.
  6. Talk to your neighbors – share what you know.
