San Gabriel Valley Vector Control has mosquito traps throughout the region. Mosquitos from these traps are gathered and tested on a regular basis.

Vector Control will continue to monitor Creekside Park and treat any potential mosquito breeding areas. They have no current plans for area-wide spraying. All City park activities are proceeding as scheduled, including summer concerts and movies. 

Residents can continue to enjoy the outdoors as usual, however if you are outdoors between dusk and dawn, you are advised to: 

  • Wear mosquito repellent (products containing DEET are best). 
  • Wear long sleeves and long pants when outdoors during early morning or evening hours when mosquitoes are most active
  • Wear loose-fitting clothes in light colors

Residents can help control the mosquito pollution by:

  • Preventing mosquito entrance into structures by repairing or installing window and door screening
  • Eliminating any standing water from around your home
  • Reporting any standing water in your neighborhood to SGVVC.

Residents can visit the San Gabriel Valley Mosquito and Vector Control District website ( for more information on West Nile Virus and other “Vectors” (a term which generally refers to, but is not limited to, mosquitoes, flies, other insects, ticks, mites, and rats capable of transmitting human disease or discomfort).

Additionally, residents are encouraged to report any dead birds to the California West Nile Hotline at 1-877-WNV-BIRD (1-877-968-2473) or online at (this website shows all reported occurrences of dead birds, as well as reported equine and human cases of West Nile Virus).

Are you seeing "GIANT" mosquitoes? Good news - those are not mosquitoes, but a close relative - the crane fly. Crane flies do not bite nor transmit disease. They only live a short time as adults and do serve as an important food source for birds. If they get inside the house, just take them back outside.
